The predetermined amount of each granule obtained in the above formulation example was placed in the container, and the temperature of the solution in the container was adjusted to 25 ± 1.0 ° C, and the container was placed under temperature management. Three days after the granules were placed and after 7 days, a solution of about 2 mL of the solution in the center of each container was sampled using a poly spuit. The sampled solution was analyzed by a high-speed liquid chromatograph under predetermined conditions, and the concentration of isothiazide in the sampled solution was quantified, and the dissolution rate of isotianil was calculated using the following formula.

Further, the amount of the agricultural granules used in the test was such that the concentration (maximum elution concentration [ppm]) when all the isotianil contained in the granules were dissolved in water was 0.63 ± 0.05 ppm.

Dissolution rate of isothiazide (%) = (Isothiazide concentration in the sampled aqueous solution [ppm] / maximum dissolution concentration of the pesticide granules in the dissolution test in the supply water [ppm]) × 100
