Description

  The present invention relates to an agrochemical packaging bag in which a composition containing an agrochemical active ingredient is encapsulated in a water-soluble film and further encapsulated in a moisture-proof film.

  In a pesticide package that contains a composition containing an agrochemical active ingredient in a water-soluble film, the water-soluble film may be hardened or softened. Sometimes it sticks to the hand. As a method for preventing such deterioration of the water-soluble film, it has been proposed to coat a pesticide package body with the moisture content in the water-soluble film adjusted to a specific range with a moisture-proof bag (see Patent Document 1).

In addition, in a water surface dropping type agricultural chemical formulation in which a water surface floating granular agricultural chemical is packaged in a water-soluble film bag having a specific dissolution time, the water content in the granular agricultural chemical is improved in order to improve the floating property of the granular agricultural chemical. It has been proposed to adjust to a specific range (see Patent Document 2).
JP-A-6-3321702 JP 2000-319102 A

  However, even if the moisture-proof bag is coated with the agrochemical package in which the water content of the water-soluble film is adjusted to a specific range as in Patent Document 1, the water-soluble film is cured or softened during storage. The present inventors have found that the pesticide package may break the bag during transportation or spraying or may adhere to the hand during spraying.

  Therefore, as a result of intensive studies, the present inventors have found that the agrochemical packaging body in which the composition containing the agrochemical active ingredient is encapsulated in the water-soluble film is further contained in the agrochemical packaging bag in which the moisture-proof film is encapsulated. The difference between the equilibrium moisture content of the product at 25 ° C. and 40% relative humidity and the moisture content of the composition immediately before inclusion in the water-soluble film is set to −2.0% to 2.0%. It has been found that the water-soluble film becomes difficult to harden or soften during this time.

  That is, the present invention relates to the agrochemical packaging bag described in [1] to [4] below and the agricultural chemical packaging body described in [5] or [6] below.

  [1] An agrochemical packaging body in which a composition containing an agrochemical active ingredient is encapsulated in a water-soluble film is an agrochemical packaging bag in which the composition is further encapsulated in a moisture-proof film. A pesticide packaging bag in which the difference between the equilibrium moisture content at 40% and the moisture content of the composition immediately before inclusion in the water-soluble film is -2.0% to 2.0%.

  [2] The agrochemical packaging bag according to [1], wherein the composition containing the agrochemical active ingredient is a solid composition.

  [3] The agrochemical packaging bag according to [1], wherein the composition containing the agrochemical active ingredient is a granular composition.

  [4] The agricultural chemical packaging bag according to any one of [1] to [3], wherein the water-soluble film is made of polyvinyl alcohol.

  [5] A pesticide packaged body contained in the pesticide packaging bag according to any one of [1] to [4].

  [6] The agricultural chemical package according to [5], which is applied to the water surface.

  In the agrochemical packaging bag of the present invention, since the water-soluble film of the agrochemical packaging contained during storage is difficult to harden or soften, it is difficult to break the bag during transportation or spraying, and is difficult to adhere to the hand during spraying.

  The difference between the equilibrium moisture content of the composition containing the pesticidal active ingredient used in the present invention at 25 ° C. and 40% relative humidity and the moisture content of the composition immediately before inclusion in the water-soluble film is −2.0% to 2 0.0%. By keeping this difference in moisture content within the above range, the water-soluble film of the agricultural chemical package contained while the agricultural chemical packaging bag is stored is hardly cured or softened. It is presumed that the reason why the water-soluble film is difficult to harden or soften is that moisture is difficult to move between the water-soluble film of the agricultural chemical package and the composition containing the agricultural chemical active ingredient during storage. The water content is a percentage by weight of water contained in the composition and is a value according to the Karl Fischer method.

  The form of the composition containing the pesticidal active ingredient used in the present invention is not limited. For example, the composition includes a soluble concentrate, an emulsifiable concentration, a suspension concentrate, a concentrated emulsion, a support. Suspoemulsion, microemulsion, wettable powder, water soluble powder, dustable powder, water dispersible granule, water soluble granule (water soluble) Various forms such as granule, granule, tablet, and emulsifiable gel can be adopted. Among these, preferred forms are solid compositions such as wettable powders, aqueous solvents, granular wettable powders, granular aqueous solvents, powders, granules and tablets. More preferred forms are granular compositions such as granule wettable powder, granule water solvent and granules.
