Description

The present invention relates to a solid pesticide composition, more preferably a pesticide formulation in which the composition is encapsulated in a water-soluble film, a method for producing the composition and the pesticide formulation, a method for applying the composition and the pesticide formulation, and a slurry for producing the composition.

Conventionally, when a highly hydrolyzable pesticide active ingredient is used in a liquid formulation or a solid formulation, the high hydrolyzability of the active ingredient causes the active ingredient to decompose significantly in the formulation when the formulation is stored for a long period of time. For this reason, for example, by incorporating a decomposition inhibitor into the formulation to suppress the decomposition of the active ingredient, the expiration date of a product containing the active ingredient could only be a minimum of three years, taking into account the distribution of the product. However, consumers desire products with longer expiration dates that are convenient to use, and suppliers desire products with longer expiration dates to reduce product loss due to expiration and to rationalize product costs by extending the expiration date. In particular, there is a strong desire from consumers and suppliers to extend the expiration date to three years or more.

Patent No. 5810009 WO2017/146147

When a solid pesticide composition is stored under high temperature conditions, the decomposition of the pesticide active ingredient in the formulation may be accelerated. To date, methods of adding anti-decomposition agents have been proposed as a measure to suppress the decomposition of the pesticide active ingredient (e.g., Patent Documents 1 and 2).

However, the invention described in Patent Document 1 is a method of suppressing the decomposition of the pesticide active ingredient by, for example, blending a maleic acid/acrylic acid copolymer or a salt thereof in the formulation as an inhibitor for the decomposition of the pesticide active ingredient, and the invention described in Patent Document 2 is a method of suppressing the decomposition of the pesticide active ingredient by, for example, blending starch such as corn starch in the formulation as an inhibitor for the decomposition of the pesticide active ingredient. However, the stabilizing effect on the pesticide active ingredient in both of the inventions described in Patent Documents 1 and 2 is not necessarily sufficient, and it is difficult to ensure storage stability that is practically usable.

The objective of the present invention is to provide a solid pesticide composition in which the hydrolysis of a highly hydrolyzable pesticide active ingredient is suppressed and the storage stability of the pesticide active ingredient is improved.

The present inventors have conducted intensive research to solve the above problems, and as a result have found that by blending a slurry having a specific surface area of at least 60,000 ^cm2 / ^cm3 containing a highly hydrolyzable pesticide active ingredient or its salt, an alkylnaphthalenesulfonate or a condensate thereof, and a polyoxyethylene mono-, di-, or tristyrylphenyl ether mono-, di-phosphate ester, and ammonium sulfate, the hydrolysis of the pesticide active ingredient is suppressed and the storage stability of the pesticide active ingredient is improved, thereby completing the present invention.

The method for producing the solid pesticide composition of the present invention comprises the steps of:
(a) a step of mixing and wet-grinding a highly hydrolyzable agricultural chemical active ingredient or its salt, an alkylnaphthalenesulfonate or its condensate, a polyoxyethylene mono-, di- or tristyrylphenyl ether mono- or diphosphate ester, and, if necessary, other auxiliary ingredients, to obtain a slurry containing the agricultural chemical active ingredient and having a specific surface area of at least 60,000 ^cm2 / ^cm3 ;
It is characterized by including a step (b) of mixing the slurry obtained in the step (a), ammonium sulfate and, if necessary, other auxiliary components, followed by wet granulation to obtain granules, and a step (c) of drying, crushing and comminuteing the granules obtained in the step (b).

When the pesticide active ingredient is a solid, the pesticide active ingredient is usually finely ground by a dry or wet method before use to produce the solid pesticide composition of the present invention.

"Other auxiliary ingredients" include, for example, defoamers, binders, dispersants, surfactants, bulking agents, or minerals.

"Wet grinding" can be carried out by known methods, for example, using 3/16-inch steel balls as the grinding medium and rotating the Attritor (registered trademark) Type 1S (manufactured by Nippon Coke and Engineering Co., Ltd.) at a rotation speed of 200 rpm.

"Wet granulation" may be carried out by a known method. For example, when granulating a mixture containing an active ingredient of an agricultural chemical, water may be added and the mixture may be granulated using a granulator such as an extrusion granulator, a fluidized bed granulator, an agitation granulator, or a tumbling granulator.

In the present invention, the "slurry" may refer to the liquid composition obtained in step (a) of [19] above, for example, a liquid composition obtained by suspending and mixing a highly hydrolyzable pesticide active ingredient or its salt, an alkylnaphthalenesulfonate or its condensate, a polyoxyethylene mono-, di- or tristyrylphenyl ether mono- or diphosphate ester, and other auxiliary ingredients as necessary in water or the like, and wet grinding. Alternatively, since the liquid composition is dried through steps (b) and (c), in the solid pesticide composition of the present invention, the "slurry" may refer to a solid composition containing a highly hydrolyzable pesticide active ingredient or its salt, an alkylnaphthalenesulfonate or its condensate, a polyoxyethylene mono-, di- or tristyrylphenyl ether mono- or diphosphate ester, and other auxiliary ingredients as necessary.

The "slurry" of the present invention has a specific surface area of at least 60,000 cm ² /cm ³ .
The term "specific surface area" refers to the specific surface area calculated by integrating the volume distribution obtained using a laser diffraction/scattering type particle size distribution measuring device (for example, LA-960 manufactured by Horiba, Ltd.).

The solid pesticide composition of the present invention can be used as a pesticide formulation. For example, the composition can be encapsulated in a water-soluble film to produce a pesticide formulation.

The above-mentioned "water-soluble film" refers to a film or sheet that has the property of dissolving or dispersing in water, and examples of its constituent materials include those made of polyvinyl alcohol or its derivatives, those made of polyvinyl alcohol-based fibers (e.g., nonwoven fabric), those made of pullulan films, those made of sodium carboxymethylcellulose and cellulose, and those made of polyethylene oxide or its derivatives. In particular, films made of polyvinyl alcohol or its derivatives are themselves easily dispersible or soluble in water, and have the property of spreading the solid pesticide composition of the present invention on the water surface.

The solid pesticide composition of the present invention may be applied to paddy fields by directly spraying it by hand. It may also be applied by spraying it using a pesticide sprayer. Alternatively, the solid pesticide composition of the present invention may be encapsulated in a water-soluble film to form a pesticide formulation, which may then be directly sprayed on paddy fields to apply the pesticide formulation.

The solid pesticide composition of the present invention can be used by directly pouring it into the paddy field by hand from a box, bottle, bag, or the like with a suitable opening, by using a pesticide sprayer, or by packaging it in water-soluble film or sheet and throwing it into the paddy field from the ridges.

The above "pesticide sprayer" refers to devices that are powered by an engine or motor, such as unmanned helicopters, drones, and powered sprayers.

The application rate of the solid pesticide composition of the present invention can be increased or decreased as appropriate depending on the target pests and weeds, but the solid pesticide composition can be used as is or by encapsulating the solid pesticide composition in a water-soluble film in a conventional manner as a pesticide formulation. When the solid pesticide composition is packaged in a water-soluble film, for example, a PVA film, the weight of one package is usually 5 to 200 g, preferably 10 to 60 g, taking into consideration ease of throwing, and the number of packages is usually 2 to 40 packages per 10 ares, preferably 4 to 20 packages, in order to achieve a sufficient biological effect.

Test Example 1
The solid pesticide compositions produced in Examples 6 to 10 and 12 and Comparative Examples 8 to 16 were sealed in polyethnium packaging and stored in a thermostat at 54 ° C for 14 days (corresponding to a 3-year expiration date) and 28 days (corresponding to a 5-year expiration date). The pyrazolate content in the solid pesticide composition before and after storage was quantified by high performance liquid chromatography to evaluate the storage stability of pyrazolate. The results were calculated as residual rates from the pyrazolate content before and after storage (the following formula). In each storage period (54 ° C x 14 days and 54 ° C x 28 days), if the residual rate is 94.0% or more, the expiration date of 3 years or 5 years can be guaranteed. The following judgment was made based on the criteria.
◯: Expiration date can be extended to 5 years △: Expiration date can be guaranteed for 3 years, but cannot be extended to 5 years ×: Expiration date cannot be guaranteed for 3 years Remaining rate (%) = [(pyrazolate content after storage)/(pyrazolate content before storage)] x 100 The results of the test examples are shown in the table below.

As is clear from the test examples, the solid pesticide composition of the present invention was able to improve the storage stability of pyrazolate, which was difficult to achieve with the formulations made using the known techniques given as comparative examples, and a solid pesticide composition was obtained that can extend the expiration date.

The solid pesticide composition of the present invention has excellent storage stability and is a useful formulation as an agricultural material.
