However, there is a huge amount of information about pesticides, and for example, there may be multiple ways to use a single pesticide and multiple times it can be used. This makes it difficult for users who grow crops to grasp which pesticides can be used on their crops, how to use them, and how many times they can be used. In addition, from the perspective of reducing the burden on the human body and the environment, and from the perspective of the Agricultural Chemicals Control Act, the amount of pesticide used must be accurately managed. In other words, farmers face a double difficulty: not only is it difficult to grasp which pesticides can be used on their crops, how to use them, and how many times they can be used, but they also have to strictly manage the amount used.

Therefore, the present invention has been made in consideration of these points, and has an object to enable a user who cultivates crops to easily know which pesticides he or she owns that can be used .

<Configuration example of pesticide information management system 10>
1 shows a first configuration example of a pesticide information management system 10 according to this embodiment. A user 20 is a pesticide user who cultivates crops using pesticides. Pesticides must be used appropriately based on standards and the like set by laws such as the Agricultural Chemicals Control Act and the Fertilizer Control Act. The standards for pesticide use include, for each pesticide product, the applicable crop, the amount used per unit area or dilution ratio, the time of use, the number of times of use, the number of times the ingredients contained in the pesticide are used, and the like.

Therefore, the user 20 must check the different information for each pesticide product from among the vast amount of information, and cultivate crops using the appropriate amount and method of use. For example, the user 20 must check the appropriate amount and method of use of the pesticide when using multiple pesticide application methods in the process of cultivating crops, when using multiple pesticides, when cultivating multiple crops, when purchasing new pesticides, etc.

The pesticide information management system 10 according to this embodiment displays the method of use and the number of times the pesticide can be used for the crops cultivated by the user 20 on the information terminal 100 used by the user 20, so that the user 20 can easily understand the number of times the pesticide can be used. The pesticide information management system 10 includes the information terminal 100 and the pesticide information management device 200.

The information terminal 100 is used by a user 20 and is a terminal capable of communicating with the pesticide information management device 200. It is preferable that the information terminal 100 is capable of communicating with the pesticide information management device 200 via a network 30. The information terminal 100, for example, transmits information input by the user 20 to the pesticide information management device 200 and receives display information generated by the pesticide information management device 200. The information terminal 100 is, for example, a portable terminal such as a smartphone, tablet PC, or small PC. The information terminal 100 has a display unit 110, a reception unit 120, and a display control unit 130.

The display unit 110 displays still images, videos, etc., output from the information terminal 100. The display unit 110 is a liquid crystal display or the like. It is preferable that the display unit 110 is a touch panel display having a position input function. In this case, the display unit 110 also functions as the reception unit 120. In this embodiment, an example in which the display unit 110 also functions as the reception unit 120 will be described.

The reception unit 120 receives input from the user 20. Alternatively or in addition to this, the reception unit 120 may have an input device such as a keyboard or a mouse. Specific input from the user 20 that the reception unit 120 receives will be described later.

The display control unit 130 causes the display unit 110 to display the display information acquired from the pesticide information management device 200. The user 20 starts the operation of the pesticide information management system 10, for example, by executing an application pre-installed in the information terminal 100, and the display control unit 130 causes the display information to be displayed on the display unit 110. In addition, when the display unit 110 functions as the reception unit 120, the display control unit 130 may display an input screen that receives input from the user 20.

The pesticide information management device 200 acquires information input by the user 20 to the information terminal 100 and generates display information to be displayed on the display unit 110 of the information terminal 100. The pesticide information management device 200 includes a communication unit 210, an acquisition unit 220, a storage unit 230, an extraction unit 240, a display information generation unit 250, and a count management unit 260.

The communication unit 210 communicates with the information terminal 100. For example, the communication unit 210 communicates with the information terminal 100 via the external network 30. It is desirable that the communication unit 210 is configured to be able to communicate with the registered information terminal 100. For example, the communication unit 210 receives information transmitted from the information terminal 100. In addition, the communication unit 210 transmits display information generated by the pesticide information management device 200 to the information terminal 100.

The acquisition unit 220 acquires information input by the user 20 to the information terminal 100 via the communication unit 210. The acquisition unit 220 may also acquire information on pesticides as pesticide product data from an external database 40 or the like. The acquisition unit 220 has a crop information acquisition unit 222 and a performance information acquisition unit 224.

The crop information acquisition unit 222 acquires crop information indicating the crop from the information terminal 100 used by the user 20. The crop information indicates the crop cultivated by the user 20, such as strawberries, Japanese mustard spinach, etc. The performance information acquisition unit 224 acquires usage performance information indicating the method of use and the number of times of use of the pesticide used by the user 20 from the information terminal 100. The method of use and the number of times of use of the pesticide contained in the usage performance information will be described later.

The storage unit 230 stores the information acquired by the acquisition unit 220. The storage unit 230 may also store intermediate data, calculation results, thresholds, reference values, parameters, etc. that are generated (or used) by the pesticide information management device 200 during its operation. The storage unit 230 may also supply the stored data to the requester in response to a request from each unit in the pesticide information management device 200. The storage unit 230 may also store pesticide product data in advance.

For example, when a computer such as a server functions as the pesticide information management device 200, the memory unit 230 may store information such as an OS (Operating System) that causes the computer to function, and programs. The memory unit 230 may also store various information including a database that is referenced when the program is executed. For example, the computer functions as at least a part of the pesticide information management device 200 by executing the program stored in the memory unit 230.

The storage unit 230 includes, for example, a ROM (Read Only Memory) that stores a BIOS (Basic Input Output System) of a computer or the like, and a RAM (Random Access Memory) that serves as a working area. The storage unit 230 may also include a large-capacity storage device such as a HDD (Hard Disk Drive) and/or an SSD (Solid State Drive). The computer may further include a GPU (Graphics Processing Unit) or the like.

The extraction unit 240 extracts, from the pesticide product data, pesticides that can be used for the crop indicated by the crop information as usable pesticides. The pesticide product data may be stored in advance in the storage unit 230, or alternatively, the acquisition unit 220 may acquire it from an external database 40 or the like. The pesticide product data is, for example, data made public by administrative agencies such as the Ministry of Agriculture, Forestry and Fisheries. The pesticide product data may also be data made public by pesticide manufacturers, distributors, etc.

The pesticide product data includes, for example, data indicating, for each pesticide product, the applicable crop, the amount used per unit area or dilution ratio, the time of use, the number of times the pesticide has been used, and the like. In this case, the extraction unit 240 extracts, from the pesticide product data, pesticides for which the crop indicated by the crop information is the applicable crop, as usable pesticides. For example, the extraction unit 240 searches the pesticide product data and extracts, from among the pesticides included in the pesticide product data, pesticides for which the crop indicated by the crop information is the target crop, as usable pesticides. The extraction unit 240 may store information on the extracted usable pesticides in the storage unit 230.

The display information generating unit 250 generates display information for displaying on the display unit 110 of the information terminal 100 multiple combinations of the usage method and the number of times that the pesticide can be used for the crop indicated by the crop information. If there is a usable pesticide extracted by the extraction unit 240 as a pesticide that can be used for the crop indicated by the crop information, the display information generating unit 250 generates a combination of the usage method and the number of times that the usable pesticide (there may be multiple pesticides) can be used as display information.

The display information generating unit 250 also causes the communication unit 210 to transmit the generated display information to the information terminal 100. When the count management unit 260 changes the display information, the display information generating unit 250 updates the display information and causes the communication unit 210 to transmit the updated display information to the information terminal 100.

The number of times management unit 260 changes the value of the number of times of use of the display information based on the usage history information acquired by the history information acquisition unit 224. For example, the number of times management unit 260 decreases the first number of times of use, which is the number of times that the method of use corresponding to the method of use of the pesticide input in the display information can be used, by the number of times of use input, depending on the method of use and the number of times of use of the pesticide input by the user 20.

The number of times management unit 260 also reduces, for example, not only the first number of times that can be used corresponding to the method of use indicated by the usage history information, but also the second number of times that can be used, which is the number of times that can be used for the method of use with the maximum number of times that can be used, by the number of times that can be used indicated by the usage history information. The more specific operations of the display information generation unit 250 and the number of times management unit 260 described above will be described next.

<Example of operation flow of the pesticide information management system 10 of the first configuration example>
Fig. 2 shows an example of the operation flow of the pesticide information management system 10 of the first configuration example. The pesticide information management system 10 executes the operations of S410 to S490 in Fig. 2 to display information on the information terminal 100 of the user 20 that enables the user 20 to easily grasp how to use a pesticide and the number of times it can be used.

First, the user 20 executes an application installed on the information terminal 100 to start the operation of the pesticide information management system 10. In this case, it is desirable that the application is configured so that the operation of the pesticide information management system 10 can be executed by inputting a password or by user authentication, etc.

The display control unit 130 of the information terminal 100, for example, displays a menu or the like and allows the user 20 to select whether or not to use past data. Here, the past data is display information that the user 20 has previously operated the pesticide information management system 10 to display on the display unit 110. The reception unit 120 receives the selection from the user 20 (S410). When the reception unit 120 receives that the user 20 has newly displayed information on the information terminal 100 (S410: No), it receives input of crop information from the user 20.

Figure 3 shows an example of the display of the display unit 110 of the information terminal 100 according to this embodiment. Figure 3 shows an example of an input screen displayed on the display unit 110 when the display control unit 130 causes the user 20 to input crop information. The display unit 110 functions as the reception unit 120 and receives input from the user 20. The reception unit 120 has a crop information reception unit 122 that receives input of crop information indicating the crop cultivated by the user. The reception unit 120 may also receive input of the cultivation location and cultivation area of the crop. The information terminal 100 transmits the information received by the reception unit 120 to the pesticide information management device 200. As a result, the crop information acquisition unit 222 of the pesticide information management device 200 acquires the crop information (S420).

Next, the extraction unit 240 extracts, from the pesticide product data, pesticides that can be used for the crop indicated by the acquired crop information as usable pesticides (S430). The extraction unit 240, for example, reads out pesticide product data previously stored in the storage unit 230 and extracts usable pesticides. Alternatively, the extraction unit 240 may extract usable pesticides using pesticide product data acquired by the acquisition unit 220 from an external database 40. For example, when the crop information is "strawberry", the extraction unit 240 extracts pesticides such as "Movento Flowable" as usable pesticides.

Next, the display information generating unit 250 generates display information based on the usable pesticides extracted by the extracting unit 240 (S440). For example, the display information generating unit 250 generates information showing combinations such as "spraying, 3 times" and "irrigation, 1 time" as display information for "Movent Flowable." Here, "spraying," which is one method of using a pesticide, refers to a method of spreading the pesticide on objects such as plants and soil. Also, "irrigation" refers to a method of allowing the pesticide to soak into the soil in a diluted form.

The display information generating unit 250, for example, stores the generated display information in the storage unit 230. Then, the display information generating unit 250 transmits the generated display information from the communication unit 210 to the information terminal 100. As a result, the display control unit 130 of the information terminal 100 displays the display information received from the communication unit 210 of the pesticide information management device 200 on the display unit 110 (S450).

Figure 4 shows a first example of display information displayed on the display unit 110 by the information terminal 100 according to this embodiment. The example in Figure 4 shows an example in which the crop information is "strawberry" and the extracted usable pesticides are "Mospilan Water Soluble Granules," "Movent Flowable," "DuPont Venevia OD," and "Glacia Emulsion." Note that it is preferable that the display information is configured so that all of the extracted usable pesticides are displayed by operating the display unit 110 to scroll the displayed page.

It is also desirable for the display information to include information on pests and diseases that can be controlled by the use of the pesticide as applicable pest information. Figure 4 shows an example of such applicable pest information displayed for each product. As an example, the applicable pests and diseases for "Mospilan Water-Soluble Granules" are "whiteflies, thrips, aphids, and persimmon leafhoppers."

The display information includes, for each product, a combination of the method of use and the number of times that the pesticide can be used on the crop "strawberry" indicated by the crop information. Figure 4 shows an example of such a combination displayed for each product. As an example, the method of use for "Mospilan Water Soluble Granules" is "spraying," and the number of times that it can be used is "twice." The display information may also include information on the time of use, and Figure 4 shows an example in which information on the time of use, such as "Until the day before harvest," is displayed. The display information may also further include availability information indicating whether or not the method of use of the pesticide can be used, and Figure 4 shows an example in which availability information, such as "OK," is displayed for each method of use.

The pesticide information management system 10 according to the present embodiment allows the user 20 to simply input crop information into the information terminal 100, and causes the information terminal 100 to display information including the method of use and the number of times the pesticide can be used for the crop being cultivated. This allows the user 20 to easily understand the method of use and the number of times the pesticide can be used without performing complex operations.

If the reception unit 120 receives in S410 that the user 20 will use past data (S410: Yes), the communication unit 210 reads out the display information stored in the storage unit 230 and transmits it to the information terminal 100. Here, if there is a plurality of pieces of display information stored in the storage unit 230, it is preferable that the display control unit 130 displays an image that receives a selection from the user 20 to allow the user 20 to select the display information to be used (S460). This allows the display control unit 130 to display the display information generated in the past on the display unit 110 as shown in FIG. 4 (S450).

This allows the pesticide information management system 10 to allow the user 20 to check the display information that the user 20 previously displayed. In this way, the pesticide information management system 10, which has displayed the display information on the display unit 110, updates the display information displayed on the display unit 110 by acquiring further information on the pesticides used by the user 20.

When the user 20 inputs performance information indicating the performance of the pesticide use to the information terminal 100 while the application of the information terminal 100 is being executed, the performance information acquisition unit 224 of the pesticide information management device 200 acquires the input performance information as usage performance information (S470). The performance information is, for example, information indicating the usage method and the number of times of use that are checked in FIG. 4. The display unit 110 functions as a reception unit 120 having a performance information reception unit 124. The performance information reception unit 124 receives input of usage performance information indicating the usage method and the number of times of use of the pesticide used by the user 20 based on the display information. FIG. 4 shows an example of such a performance information reception unit 124, in which the display control unit 130 displays a check box 125 and an execution button 126 on the display unit 110. Note that the display control unit 130 may display a radio button or the like on the display unit 110 instead of the check box 125.

For example, when the user 20 operates the display unit 110 to check the check box 125 for "irrigation" of "Movent Floable" and presses the execute button 126 once, the performance information acquisition unit 224 acquires input of performance information on the one time use of "irrigation" of "Movent Floable".

Next, the display information generating unit 250 and the count managing unit 260 update the value of the number of uses of the display information based on the usage history information acquired by the history information acquiring unit 224 (S480). The count managing unit 260 decreases the first number of uses, which is the number of uses corresponding to the method of use of the pesticide indicated in the usage history information, by the number of uses indicated in the usage history information. In the example of Figure 4, the method of use of the pesticide indicated in the usage history information is "irrigation", and the number of uses is 1. Therefore, the count managing unit 260 changes the number of uses of "irrigation" in the display information from 1 time to 0 times.

The display information generating unit 250 may change the propriety information for "irrigation" whose number of times it can be used has reached 0 from "OK" to "NG." The propriety information "NG" indicates that "irrigation" cannot be used on crops. By displaying the propriety information in this manner, the user 20 can easily understand that there are methods in which the same pesticide can be used and methods in which it cannot be used.

In addition to decreasing the first number of times that it can be used, if the method of use of the second number of times that it can be used, which is the maximum number of times that it can be used in the display information, differs from the method of use of the pesticide indicated in the usage history information, the number of times that it can be used also decreases the second number of times that it can be used by the number of times that it can be used indicated in the usage history information. In the example of Figure 4, the pesticide indicated in the usage history information is "Movent Flowable", and the method of use that has the maximum number of times that "Movent Flowable" can be used is "spraying", and the number of times that it can be used is three. Since "spraying" differs from the method of use "irrigation" indicated in the usage history information, the number of times that it can be used for "spraying" in the display information decreases from three to two.

In this way, the number of times the pesticide can be used is regulated so that if there is another method of use with a greater number of times it can be used than the method actually used (first number of times it can be used), the number of times it can be used for the method of use with the greatest number of times it can be used (second number of times it can be used) is reduced by the number of times it can be used, along with the number of times it can be used for the method of use that was used. The number of times management unit 260 described above can manage the information on the number of times the pesticide can be used in the display information so as to correspond to such pesticide regulations. Furthermore, by having the number of times management unit 260 operate in this way, it is possible to prevent the user 20 from mistakenly thinking that if the method of use in which the pesticide was used is not the other method of use with the greatest number of times it can be used, the other method of use can be used more times than it actually can be used.

When the method actually used and the method with the maximum number of times it can be used are the same, the method that was used can be managed by decrementing the number of times it was used. Therefore, when the first number of times it can be used corresponding to the method of use indicated in the usage history information is the maximum among the multiple numbers of times it can be used, the number of times management unit 260 decrements the first number of times it can be used by the number of times it is used indicated in the usage history information, and does not decrement the numbers of times it can be used for the other methods of use. For example, in the example of Figure 4, if the method of use of the pesticide indicated in the usage history information is "spraying" instead of "irrigation", the number of times management unit 260 changes the number of times it can be used for "spraying" in the display information from 3 to 2, and does not change the number of times it can be used for "irrigation".

However, the user 20 may continue to use the pesticide with the method for which it can be used the maximum number of times. In this case, as the user 20 continues to use the pesticide with that method, the number of times other methods for using the pesticide can be used may reach the second number of times that it can be used, which is the maximum number of times that it can be used. In the example of FIG. 4, if the usage history information indicates that "spraying" has been used twice, the number of times management unit 260 reduces the number of times that "spraying" can be used from three times to one time. As a result, the number of times that "spraying" and "irrigation" can both be used becomes one time, and both become the second number of times that they can be used.

In this way, when there are multiple usage methods that maximize the number of times a pesticide can be used, the number of times that the pesticide can be used is managed by decrementing the number of times that the pesticide can be used for all of the usage methods that maximize the number of times it can be used, along with the number of times that the pesticide can be used for the method that was used. Therefore, when there are multiple usage methods whose number of times that the pesticide can be used corresponds to the second number of times that the pesticide can be used and the first number of times that the pesticide can be used is decremented by the number of times that the pesticide can be used, the number of times that the pesticide can be used manages the number of times by the number of times that the pesticide can be used.

For example, if the number of times that "spraying" and "irrigation" can both be used has reached 1, and the usage history information acquisition unit 224 acquires usage history information indicating that "spraying" or "irrigation" has been used once, the number of times management unit 260 reduces the number of times that "spraying" and "irrigation" can be used from 1 to 0. This allows the number of times management unit 260 to manage the information on the number of times that the pesticide can be used in the display information in accordance with the pesticide regulations.

When the count management unit 260 reduces the first and second usable counts, the display information generation unit 250 updates the display information to the reduced first and second usable counts. The display information generation unit 250 updates the display information to display information corresponding to the usable counts changed by the count management unit 260. The display information generation unit 250 then stores the updated display information in the storage unit 230, for example. The display information generation unit 250 also transmits the updated display information from the communication unit 210 to the information terminal 100. The display control unit 130 of the information terminal 100 then displays the updated display information on the display unit 110.

The pesticide information management system 10 may repeat S470 to S490 to update the display information until the user 20 performs an operation to end the operation of accessing the pesticide information management device 200 using the information terminal 100 (S490: No). When the reception unit 120 of the information terminal 100 receives an instruction from the user 20 to end the operation of the pesticide information management system 10, the information terminal 100 transmits a notification of the end of operation to the pesticide information management device 200 and ends the application. The pesticide information management device 200 ends the operation in response to the acquisition unit 220 acquiring the notification of the end of operation (S490: Yes).

The pesticide information management system 10 according to this embodiment can update the display on the information terminal 100 simply by the user 20 operating the information terminal 100 to input the method of use and number of uses of the pesticide used. This allows the user 20 to easily understand the method of use and number of times the pesticide can be used after it has been used, without having to perform complex processing of the number of uses in accordance with the pesticide regulations.

For example, user 20 may change the method of using a pesticide during the process of cultivating crops. Even in such a case, the pesticide information management system 10 updates the display information to include, for example, all pairs of the pesticide's usage methods and the number of times it can be used, so user 20 can easily grasp the number of times it can be used for different pesticide usage methods.

The above embodiment of the pesticide information management system 10 has been described as an example in which the first and second usable numbers corresponding to the usage history information are decreased by the number of uses to update the display information, but the present invention is not limited to this. A user 20 may use multiple different pesticides on a crop. In addition, a user 20 may use different pesticides on land near the land where the crop is being grown, which may result in a situation similar to that in which different pesticides have been used on the crop being grown.

For example, consider a case where user 20 uses a first pesticide and a second pesticide. If the ingredients of the first pesticide and the second pesticide are completely different, the pesticide information management system 10 can manage the usage methods and the number of times the first pesticide and the second pesticide can be used independently. On the other hand, at least some of the ingredients of the first pesticide and at least some of the ingredients of the second pesticide may be the same ingredients. In this case, when user 20 uses the first pesticide on a crop, it may have the same effect as using the second pesticide on the crop.

Therefore, it is desirable that the pesticide information management system 10 manages the method of use and the number of times that the second pesticide can be used in addition to managing the method of use and the number of times that the first pesticide can be used in response to the performance information indicating that the user 20 has used the first pesticide. For example, consider a case where the display information generating unit 250 generates display information including multiple pesticides that can be used for the crop indicated by the crop information, the performance information acquiring unit 224 acquires usage performance information including information that the pesticide used by the user 20 among the multiple pesticides is the first pesticide, and a second pesticide that contains the same ingredients as the ingredients contained in the first pesticide is present among the multiple usable pesticides.

In this case, the number of times management unit 260 reduces the first number of times that the first pesticide can be used and the second number of times that the first pesticide can be used by the number of times of use, as described above, in response to the history information indicating that the user 20 has used the first pesticide. Then, the number of times management unit 260 reduces the third number of times that the second pesticide can be used, which is the maximum number of times that the second pesticide can be used, by the number of times that the usage history information indicates.

For example, in the example of FIG. 4, the second pesticide is Movento Flowable, and the first pesticide is a pesticide containing ingredients of Movento Flowable. When the user 20 inputs to the performance information receiving unit 124 that the first pesticide has been used once, the number management unit 260 reduces the first and second usable numbers of the first pesticide in the display information by one each. The number management unit 260 then reduces the maximum number of times that Movento Flowable can be used, "sprayed," from three times to two times. This allows the pesticide information management system 10 to change and update the number of times that other pesticides containing the same ingredients as the pesticide used by the user 20 can be used. Therefore, the user 20 can easily grasp more accurate display information.

The above description has been given of an example of the pesticide information management system 10 according to this embodiment, where a combination of the usage method and the number of times the pesticide can be used corresponding to the crop information is displayed on the display unit 110 of the information terminal 100, but the present invention is not limited to this. The pesticide product data acquired from the outside by the pesticide information management system 10 may include information on a method of using the pesticide by diluting the pesticide at multiple dilution ratios. Here, the method of using the pesticide by diluting it at multiple dilution ratios is referred to as a diluted usage method. In this case, the display information generating unit 250 may generate display information for a pesticide that can be used on the crop indicated by the crop information, including a diluted usage method for diluting the pesticide at multiple dilution ratios.

For example, the display information generating unit 250 generates display information including multiple dilution ratios for one dilution use method. As an example, consider a case where the use method of pesticide A in the pesticide product data includes a dilution use method "spraying" in which the pesticide is diluted 2000 times and 3000 times and can be used four times each. In this case, the display information generating unit 250 generates display information including the information "dilution ratio 2000 times" and "dilution ratio 3000 times" in addition to the information "spraying, can be used four times".

This allows the display control unit 130 to display information such as "Spray, dilution ratio 2000 times, 4 times remaining" or "Spray, dilution ratio 3000 times, 4 times remaining" on the display unit 110. Therefore, the user 20 can easily understand that the method of using the pesticide includes multiple dilution ratios, and the dilution ratio when actually used.

When the pesticide product data includes information on such a dilution use method, the dilution ratio information may indicate a range of dilution ratios using minimum and maximum dilution ratios. In the case of such a dilution use method, the display information generating unit 250 generates display information including the minimum and maximum dilution ratios of the pesticide that can be used for the crop indicated by the crop information. The display information generating unit 250 extracts, for example, the minimum and maximum values of the ratio range, and generates display information including the extracted minimum and maximum dilution ratio information for the dilution use method.

For example, consider a case where the usage method for pesticide A in the pesticide product data includes a dilution usage method "spray" in which the pesticide is diluted "2000 to 4000 times" and can be used four times. In this case, the display information generating unit 250 extracts the information "2000" and "4000" from the information "2000 to 4000 times". As an example, the display information generating unit 250 searches for pesticide product data by including character information such as "~" and "times" in the search criteria. Then, when numeric information exists before and after the character string "~", the display information generating unit 250 extracts the number before the character string "~" as the minimum value and the number after the character string "~" as the maximum value.

Then, the display information generating unit 250 generates combinations such as "spray, dilution ratio 2000 times, usable number of times 4" and "spray, dilution ratio 4000 times, usable number of times 4" and includes them in the display information. This allows the pesticide information management system 10 to display the dilution ratio for actual use on the display unit 110 even if the pesticide product data includes information on the range of dilution ratios.

In addition, the display information generating unit 250 may add a value between the minimum and maximum values of the multiplication factor to the display information. In this case, the display information generating unit 250 generates a value obtained by multiplying the sum or difference of the minimum and maximum values by a predetermined coefficient, and further includes it in the display information. For example, the display information generating unit 250 generates combinations such as "spray, dilution factor 2000 times, usable number of times 4", "spray, dilution factor 3000 times, usable number of times 4", and "spray, dilution factor 4000 times, usable number of times 4" with a coefficient of 0.5, and includes them in the display information. An example of the display information generated in this way is shown in FIG. 5. FIG. 5 shows a second example in which the information terminal 100 according to this embodiment displays display information on the display unit 110.

The display information generating unit 250 may adjust the coefficient so that the dilution ratio is an approximate number without a fraction. For example, if the minimum value of the range of the ratio is 1000 and the maximum value is 4000, the display information generating unit 250 may set the coefficient to 1/3 and generate combinations of dilution ratios of 1000, 2000, 3000, and 4000 to include in the display information.

According to the pesticide information management system 10 of this embodiment, the user 20 can easily grasp information on the use of pesticides within the appropriate range of usage standards by simply inputting information on the crop being cultivated and the pesticide used into the information terminal 100. In this way, even if the user 20 is, for example, a farm that actually uses pesticides, the user 20 can easily grasp information on the use of pesticides by simply operating the information terminal 100, and can use the pesticides promptly. The specific operation of the number management unit 260 of such a pesticide information management system 10 will be described next.

<An example of the operation of managing the number of times that ... can be used by the number management unit 260>
Figure 6 shows an example of a table used by the count management unit 260 according to this embodiment. Here, an explanation is given of the operation of the count management unit 260 managing the number of times it can be used using a table such as that shown in Figure 6. Figure 6 shows an example of pesticide A having three usage methods, "usage method 1", "usage method 2", and "usage method 3". In the initial state of pesticide A, the number of times it can be used for "usage method 1" is set to 3, the number of times it can be used for "usage method 2" to 5, and the number of times it can be used for "usage method 3" to 1.

In this case, the second number of times that it can be used, which is the maximum number of times it can be used, is five times for "usage method 2." Here, the number of times management unit 260 defines a usage status table for pesticide A, as shown in FIG. 6(A) as an example. The usage status table is made up of the second number of times that it can be used and the numbers of times it can be used for the three usage methods. The number of times management unit 260 may store the usage status table in the memory unit 230.

Now consider a case where the history information acquisition unit 224 acquires usage history information indicating that "Usage Method 1" was used twice and "Usage Method 3" was used once. As an example, the count management unit 260 defines a history table for pesticide A as shown in FIG. 6(B). The history table is composed of the total number of uses and the number of uses of the three usage methods. The total number of uses indicates the sum (three times) of the number of uses of "Usage Method 1" (two times) and the number of uses of "Usage Method 3" (one time).

Next, the count management unit 260 updates the usage state table by subtracting each value in the achievement table from each value in the usage state table. Figure 6 (C) shows the usage state table after updating. This shows an example where the second usable count in the usage state table has been updated to 2 times by subtracting the total number of uses of 3 times from the initial state of 5 times. This shows an example where the usable count for "usage method 1" has been updated to 1 time by subtracting the number of uses of 2 times from the initial state of 3 times. This shows an example where the usable count for "usage method 3" has been updated to 0 times by subtracting the number of uses of 1 time from the initial state of 1 time.

Next, the count management unit 260 compares the updated second usable count with the usable count of each usage method, and adopts the smaller value to further update the usage status table. Figure 6 (D) shows a further updated usage status table. An example is shown in which the usable count for "usage method 1" remains at 1, since it is 1, which is smaller than the updated second usable count of 2. An example is shown in which the usable count for "usage method 2" is updated to 2, since it is 5, which is larger than the updated second usable count of 2. An example is shown in which the usable count for "usage method 3" remains at 0, since it is 0, which is smaller than the updated second usable count of 2.

The usage status table shown in FIG. 6(D), which has been updated as described above, indicates the number of times pesticide A can be used, which has been updated by the number-of-times management unit 260 in response to the usage history information. In this way, the number-of-times management unit 260 can use the table to manage the number of times the pesticide can be used. This allows the number-of-times management unit 260 to easily update the number of times multiple usage methods can be used, even if the usage history information acquisition unit 224 acquires usage history information indicating that multiple types of usage methods have been used multiple times.

In addition, the user 20 may want to check which pesticides he or she owns are usable. In this case, the pesticide information management system 10 may acquire information on the pesticides owned by the user 20, and extract information on usable pesticides from the acquired pesticide information. Such a pesticide information management system 10 will be described next.

<Second Configuration Example of Pesticide Information Management System 10>
7 shows a second example of the configuration of the pesticide information management system 10 according to this embodiment. In the pesticide information management system 10 of the second example, the operations that are substantially the same as those of the pesticide information management system 10 of the first example shown in FIG. 1 are designated by the same reference numerals, and duplicated explanations will be omitted.

In the pesticide information management system 10 of the second configuration example, the reception unit 120 of the information terminal 100 has a function of receiving input of pesticides owned by the user 20. FIG. 8 shows an example of the display of the display unit 110 of the information terminal 100 of the second configuration example. The display unit 110 also functions as the pesticide information reception unit 128.

The pesticide information receiving unit 128, for example, receives pesticide information input by the user 20 as owned pesticides. The pesticide information receiving unit 128 may also be configured to be able to display a list including multiple pesticides, and may receive a pesticide selected by the user 20 from the list as an owned pesticide. The information terminal 100 transmits the information on the owned pesticide received by the pesticide information receiving unit 128 to the pesticide information management device 200.

The acquisition unit 220 of the pesticide information management device 200 of the second configuration example further includes a pesticide data acquisition unit 226 and a pesticide information acquisition unit 228. The pesticide data acquisition unit 226 acquires pesticide product data including information on the pesticide ingredients, target crop, usage method, and number of times it can be used for each pesticide product. The pesticide data acquisition unit 226 acquires pesticide product data from an external database 40 via the network 30, for example. The external database 40 is a database made public by, for example, an administrative agency, a pesticide manufacturer, a pesticide distributor, etc. Note that the pesticide information management system 10 of the first configuration example may be provided with a pesticide data acquisition unit 226, similar to the pesticide information management system 10 of the second configuration example.

The pesticide information acquisition unit 228 acquires information for identifying the pesticides owned by the user 20. The pesticide information acquisition unit 228 acquires information on the owned pesticides transmitted from the information terminal 100.

The extraction unit 240 in the second configuration example searches the pesticide product data and extracts, from among the owned pesticides, those pesticides that are intended for the crop indicated in the crop information as usable pesticides. In this way, the extraction unit 240 extracts, from among the pesticides owned by the user 20, those pesticides that can be used for the crops cultivated by the user 20 as usable pesticides. Then, if there is a usable pesticide extracted by the extraction unit 240 as a pesticide that can be used for the crop indicated in the crop information, the display information generation unit 250 generates display information for displaying, for each usable pesticide, a combination of the usage method and number of times it can be used, which are included in the pesticide product data, on the display unit 110 of the information terminal 100.

This allows the pesticide information management system 10 to omit displaying information about pesticides that the user 20 does not own. Therefore, the user 20 can easily understand the usage method and number of times that the more important pesticides that are extracted from the pesticides that the user owns can be used.

In addition, the pesticide product data obtained from the external database 40 may show the name of the crop in the applicable crop information, or may show the classification of crops in general or vegetables. For example, the applicable crop information may show the name of a crop including "Komatsuna" or may show "vegetables" or "non-heading Brassica leafy vegetables." Also, the notation such as kanji or hiragana may differ.

Therefore, if the crop information entered by the user 20 is "Komatsuna," and the extraction unit 240 extracts only pesticides for which "Komatsuna" is registered as an applicable crop from the pesticide product data, pesticides for which "non-heading Brassica leafy vegetables" are registered as applicable crops will not be extracted as pesticides that can be used on "Komatsuna." Therefore, the extraction unit 240 further includes a category identification unit 242 and a search unit 244, and improves the accuracy of extraction of pesticides that can be used on the crop indicated by the crop information.

The category identification unit 242 identifies a higher-level category that includes crop information indicating the crops cultivated by the user 20 as the target category. The category identification unit 242 identifies the target category based on category information indicating crop classification information, for example. It is preferable that the category information be stored in advance in the storage unit 230. It is also preferable that the category information be a database generated from information on the applicable crops of the pesticide product data acquired by the pesticide data acquisition unit 226.

As an example, information including "komatsuna" in the category information is "vegetables, non-heading cruciferous leafy vegetables, komatsuna." In this way, the category information is formed, for example, of a higher-level category (vegetables, non-heading cruciferous leafy vegetables) that includes the crop (komatsuna) input by the user 20. The category information may further include a different spelling (komatsuna). For example, by using such category information, the category identification unit 242 can identify "vegetables, non-heading cruciferous leafy vegetables, komatsuna" as the target category when the crop information is "komatsuna."

The search unit 244 searches the pesticide product data using the target category as a search condition in addition to the crop information to extract usable pesticides. For example, the search unit 244 searches the pesticide product data for pesticides for which "Komatsuna" is an applicable crop, and extracts a first candidate for usable pesticides. The search unit 244 also searches the pesticide product data for pesticides for which "vegetables," "non-heading cruciferous leafy vegetables," and "Komatsuna" are applicable crops, and extracts a second candidate for usable pesticides. Then, the search unit 244 extracts, from the first and second candidates for usable pesticides, pesticides that are included in the pesticides owned by the user 20 as usable pesticides.

Alternatively, the search unit 244 may search the pesticide product data for each pesticide included in the owned pesticides owned by the user 20, and confirm whether or not the applicable crop includes the crop of the crop information. As a result, the search unit 244 extracts, from the owned pesticides, pesticides whose applicable crop includes the crop of the crop information as first candidates for the pesticide. The search unit 244 may further search the pesticide product data for each pesticide included in the owned pesticides owned by the user 20, and confirm whether or not the applicable crop includes the target category. As a result, the search unit 244 extracts, from the owned pesticides, pesticides whose applicable crop includes the target category as second candidates for the pesticide. Then, the search unit 244 extracts the first candidate for the pesticide and the second candidate for the pesticide as usable pesticides.

Note that the applicable crops in the pesticide product data may contain information indicating that certain crops are excluded. For example, the applicable crops for pesticide B may indicate "vegetables (excluding komatsuna)." In this case, pesticide B is not a pesticide that can be used on "komatsuna." Therefore, when searching pesticide product data using a target category as a search condition, it is desirable for the search unit 244 not to extract pesticides for applicable crops that contain keywords indicating that the crop indicated by the crop information is excluded. For example, the search unit 244 excludes pesticides extracted as usable pesticides whose applicable crop information in the pesticide product data contains information indicating that the crop indicated by the crop information is excluded.

In this way, the pesticide information management system 10 extracts pesticides that can be used by using search results using crop information and search results using the target category, thereby improving the accuracy of extraction of pesticides that can be used for crops. Furthermore, in response to applicable crop information indicating that the crop indicated by the crop information is to be excluded, the pesticide information management system 10 excludes the pesticide for the applicable crop from the pesticides that can be used. This allows the pesticide information management system 10 to further improve the accuracy of extraction of pesticides that can be used for crops.

<An example of an operation flow of the pesticide information management system 10 according to the second configuration example>
Fig. 9 shows an example of the operation flow of the pesticide information management system 10 of the second configuration example. The pesticide information management system 10 of the second configuration example executes the operations from S400 to S490 in Fig. 9 to display information on the information terminal 100 of the user 20 that allows the user 20 to easily understand the method of use and the number of times that the pesticides owned by the user 20 can be used.

First, the pesticide data acquisition unit 226 acquires pesticide product data (S400). Note that if pesticide product data is stored in the memory unit 230 of the pesticide information management device 200, the operation of S400 may be omitted. Also, if there is updated information in the pesticide product data, the pesticide data acquisition unit 226 may acquire only the updated information. Note that the operations of the next steps S410 and S420 have already been explained in FIG. 2, so duplicate explanations will be omitted.

Next, the pesticide information acquisition unit 228 of the pesticide information management device 200 acquires information for identifying the pesticides owned by the user 20 (S422). The display unit 110 of the information terminal 100 functions as the pesticide information acceptance unit 128 and accepts input of the pesticides owned by the user 20. The information terminal 100 transmits the information accepted by the pesticide information acceptance unit 128 to the pesticide information management device 200. As a result, the pesticide information acquisition unit 228 of the pesticide information management device 200 acquires information on the owned pesticides.

Next, the extraction unit 240 searches the pesticide product data and extracts, from among the owned pesticides, pesticides for which the target crop is the crop indicated by the crop information as usable pesticides (S430). The extraction unit 240 uses the crop information and the target category to extract usable pesticides by the category identification unit 242 and the search unit 244. Here, a case will be described in which the crop information acquired by the acquisition unit 220 indicates "Komatsuna."

When the crop information indicates "Komatsuna," the category identification unit 242 extracts information on "Vegetables, Non-heading Brassica leafy vegetables, Komatsuna, Komatsuna" that includes "Komatsuna" from the category information. Then, the category identification unit 242 identifies the target category as "Vegetables, Non-heading Brassica leafy vegetables, Komatsuna."

Next, the search unit 244 searches the pesticide product data using the search criteria of the target category "vegetables, non-heading cruciferous leafy vegetables, komatsuna" in addition to "komatsuna" indicated in the crop information. The search unit 244 extracts, from the pesticide product data, pesticides whose target crop matches at least one of the search criteria as usable pesticides. In addition, the search unit 244 excludes, from the pesticides extracted as usable pesticides, those whose applicable crop information in the pesticide product data includes information indicating "excluding komatsuna." This enables the pesticide information management system 10 to further improve the accuracy of extraction of pesticides usable for "komatsuna" from the pesticide product data.

Next, the display information generating unit 250 generates display information based on the usable pesticides extracted by the extracting unit 240 (S440). The display information generating unit 250 generates display information that, for example, adds usability information indicating whether the owned pesticide can be used to the information on the owned pesticide. As a result, for example, if the user 20 owns pesticides such as "Mospilan Water Soluble Granules," "Movent Flowable," "DuPont Venevia OD," and "Glacia Emulsion," and inputs "strawberry" as crop information, it is desirable that the usability information indicating usability, such as "OK," is displayed on the display unit 110 as the usage method of the owned pesticide, as shown in FIG. 4. The operations from S440 to S490 have already been described in FIG. 2, so repeated description will be omitted.

In the pesticide information management system 10 of the second configuration example described above, when the user 20 simply inputs crop information and information on the owned pesticides into the information terminal 100, display information including the usage method and the number of times that the pesticides owned by the user 20 can be used for the crops being cultivated is displayed on the information terminal 100. This allows the user 20 to easily understand the usage method and the number of times that the pesticides owned by the user 20 can be used without performing complicated operations. In addition, by inputting into the information terminal 100 that the owned pesticide has been used, the user 20 can easily understand the number of times that the pesticide can be used after it has been used.

Although the present invention has been described above using embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments, and various modifications and changes are possible within the scope of the gist of the invention. For example, all or part of the device can be configured by distributing or integrating functionally or physically in any unit. In addition, new embodiments resulting from any combination of multiple embodiments are also included in the embodiments of the present invention. The effect of the new embodiment resulting from the combination also has the effect of the original embodiment.
