Currently, water-dispersible granules containing various active ingredients of pesticides are being developed. Agent. The water-dispersible granules are usually obtained by adding a humectant, a dispersing agent, a binder, a bulking agent and the like to the active ingredient (pesticide) of the pesticide, and granulating the granules into granules. The water-dispersible granules are usually diluted with water and suspended for 1 〇 to 1 〇〇〇 () times. Water-dispersible granules are required to rapidly disintegrate after being placed in water, and many proposals have been made for improving disintegration and dispersibility. The right-handedness or poor dispersion is the result of the separation of the active ingredients in the water, the uneven distribution, and the phytotoxicity of the crops. It is difficult to directly perform the granulation of the active ingredient of the agricultural carp and the low melting point of the liquid at normal temperature. As a result of &, the method of preparing the pesticide into a mixture with a large amount of inactive substances, and a method of adsorbing a solution of the active ingredient of the pesticide to the preparation of Zhao Zhao has been proposed (Non-patent 201012393) ). In addition, the following two have been proposed: the granules obtained by mixing and granulating the active ingredients of the liquid at room temperature, the saccharides, the burned products of the wet method, the soil, and the ionic surfactant. (Special 2 literature 1); or at the melting point | 70. (: A water-dispersible granule obtained by adding a solvent of a wet method and an anionic surfactant to the active ingredient of the following pesticides and further adding a solvent and a water-soluble carrier to granulate (Patent Document 2). The water-dispersible granules proposed in the above-mentioned products exhibit good disintegratability and dispersibility in the water after the granulation is completed or after storage at a low temperature. However, storage in a warehouse without temperature adjustment equipment, etc. In the case of prolonged exposure to a high-temperature environment, there may be a problem that disintegration and dispersibility may occur, and the active ingredients of the pesticide may be separated and unevenly distributed in the water. - As an example of improved disintegration and dispersibility And itj is used to set the water-dispersible granules obtained by granulation with a melting point or a softening point of 7 (the active ingredient of the pesticide below rc, the n ❺ sulphated aminate as a dispersing agent, and a mixture of adsorbing carriers).

The evaluation of the water-dispersible granules obtained in the examples and the comparative examples was carried out by the following method. These results are shown in Table 1. (Evaluation of self-dispersibility) In a test tube containing 100 mL of water so that the distance from the water surface to the bottom is about 18 〇 mm, the test tube is filled with 3 degrees hard water according to the pesticide step test method. ) mL, in which the water-dispersible granules were slowly poured, and the state in which the water-dispersible granules settled to the bottom of the granules was listed in the following Kihamese. 21 201012393 〇: Water-dispersible granules have begun to disintegrate between the bottom of the test tube. X: The water-dispersible granules did not completely disintegrate between the bottoms of the contact tubes. ◦ indicates self-dispersibility; X indicates no self-dispersibility; 〇~χ indicates substantially self-dispersibility, but some particles are not self-dispersible. X~◦ indicates that there is substantially no self-dispersibility, but some of the particles are self-dispersible. (Evaluation of disintegration) The water containing UHhnL is such that the distance from the water surface to the bottom is about 3 inches of the space volume of the rigid surface, and 3 degrees of hard water (10) mL is charged according to the pesticide step inspection method, and then Slowly put into the water-dispersible granule beta agent. The operation of inverting and restoring was repeated at a frequency of 2 seconds after the introduction of the test for 30 seconds. The number of revolutions (referred to as the number of disintegrations) until the water-dispersible granules completely disintegrated was measured. The less the number of disintegration reversals, the better the disintegration. (Settling amount (dispersibility)) After the number of times of disintegration inversion was measured, the test tube was further inverted and restored three times in a frequency of 2 seconds i. After 30 minutes from the end of the reverse operation of the inversion, the amount of sedimentation (mL) was measured. The smaller the amount of sedimentation, the more excellent the properties. (High-temperature storage test) The water-dispersible granules obtained in the examples and the comparative examples were placed in a thermostatic chamber of 54 liters for 14 days. For the water-dispersible granules after the preservation of the 14-day-old, the field seven from the H mesh/JD, the dispersibility, the solvability, and the sedimentation amount of the self-dispersing boring tool were evaluated in the same manner as described above. 22 201012393 Table 1 ~~TM ----------- ______________ 54°C×14 days of self-dispersive disintegration at the time of completion of manufacturing [times] Settlement ΓτηΠ Self-dispersibility ------- Ο ~乂" Disintegration [次] Λ 沉降 Settlement Example 1 _____〇11 0.01 Comparative Example 1 〇11 <0.01 X LH 17 o.os 〇^ Comparative Example 2 _____g 12 0.04 X 1 Q --- -- Λ A Comparative Example 3 〇11 001 ~X l Ο 15 0.2 — As shown in Table 1, the water-dispersible granules of the prior formula have self-dispersibility, disintegration in water and dispersion as soon as the manufacturing is completed. It is also excellent in the properties. However, in the case of storage after the temperature is maintained, the self-dispersibility disappears, and the disintegratability and dispersibility are lowered. On the other hand, the water-dispersible granule of the present invention maintains self-dispersibility even after storage at a high temperature, and the degree of reduction in disintegratability and dispersibility is small. The water-dispersible granule of the present invention can be applied to agricultural and horticultural pesticides even if it does not reduce disintegration and dispersibility after storage at a high temperature.
