Description

  The present invention relates to a solid agricultural chemical formulation.

  Among solid agrochemical formulations, wettable powders, granule wettable powders, aqueous solvents and granular water solvents are known as solid agrochemical formulations in which the use form is a form in which a chemical solution obtained by mixing with water is applied. ing. Such a solid agrochemical formulation has a problem that work efficiency is lowered when bubbles are generated when mixed with water, and is required to have low foaming properties. In addition, water-insoluble components such as agrochemical active compounds in the chemical solution obtained by mixing the solid agricultural chemical formulation and water precipitate, and even if stirred, the water-insoluble component does not easily disperse in the chemical tank of the sprayer. In the case where it remains on the bottom, there is a problem that the effectiveness as an agrochemical is not sufficiently exhibited, and it becomes difficult to clean the tank, and therefore, it is required to have good redispersibility. Improvements are being made to meet such demands, and various solid agrochemical formulations have been proposed (see, for example, Patent Document 1).

Test example 1
Put 200 ml of deionized water at 30 ° C into a 250 ml stoppered graduated cylinder, add 1.33 g of the test preparation, plug the stopper, turn the graduated cylinder 180 ° in 1 second and restore it in 1 second 30 times. After standing, the amount of foam after 1 minute was measured. The results are shown in Table 1.

Test example 2
By adding 250 ml of deionized water to a graduated cylinder with a 250 ml stopper, adding 1.67 g of the test preparation, plugging it, turning the graduated cylinder 180 ° in 1 second, and returning it to its original position in 1 second, about 30 times. After completely dispersing the test preparation, it was allowed to stand at room temperature. After 24 hours, the graduated cylinder was turned upside down at a rate of once per second, and the number of falls required for complete redispersion of the water-insoluble component precipitated at the bottom of the graduated cylinder was measured. The results are shown in Table 2.
