This coarse disintegration has been carried out The sieve was used to obtain the pesticide granule of Comparative Example e.

The dissolution rate of the active ingredient in each of the above tables was measured by the following method.

A 500 ml beaker was placed in 300 ml of water and stirred slowly at a water temperature of 25 ± 1 °C.

The pesticide granules were put therein and stirred slowly at a water temperature of 25 ± 1 °C. After the pesticide granules are put into the granules for a set period of time, 500 μl of water in the beaker is analyzed by high-speed liquid chromatography to calculate the concentration of the active substance of the pesticide. The dissolution rate of the active ingredient is determined from the concentration of the pesticide active material and the amount of the active material contained in the pesticide granule used.

Further, the dose of the pesticide particles used for the dissolution rate of the active ingredient is determined as the amount of the active ingredient of the pesticide as follows.

Ferimzone: 400mg

Furametpyr: 130mg

Compound A: 76 mg

Imazosulfuron: 225mg

Clothianidin: 850mg

Tricyclazole: 750mg

Futhalide: 13mg

[Industrial use]

According to the present invention, a pesticide granule capable of suppressing dissolution of an active ingredient of a pesticide in water and capable of sustaining an active ingredient of the pesticide for a long period of time can be obtained.
