PROBLEM TO BE SOLVED: To provide a granular agrochemical composition containing orysastrobin, in which elution of orysastrobin in water is suppressed.SOLUTION: The granular agrochemical composition comprises orysastrobin, gelatinized starch and bentonite; and the composition contains 20 to 800 pts.wt of the bentonite with respect to 100 pts.wt of the gelatinized starch, and has a total pore volume of 0.18 to 0.24 ml/g and a median diameter of pores of 0.13 to 0.24 μm. The granular agrochemical composition further suppresses elution of orysastrobin in water and can improve sustainability of a bactericidal effect in a rice field. |
