A method of the utilization of a fungicidal composition characterized by treating seeds of a subject plant or a cultivation carrier for sowing the subject plant with an effective amount of a composition containing, as the active ingredient, one or more members selected from among 1,2,3-thiadiazole derivatives represented by general formula (I) and salts thereof:
wherein R1 represents H, (C1-6)alkyl or C3-7cycloalkyl, and R2 represents CO-Y-R3 (wherein R3 represents H, (halo)(C1-20)alkyl, (halo) (C2-20)alkenyl, (substituted) carbamoyl(C1-6)alkyl, (substituted) phenyl, (substituted) phenyl(C1-6)alkyl, a 5- to 6-membered heterocycle having one or more hetero atoms selected from among O, S and N, etc.). This method is superior in the effect of controlling disease injury such as Pyricularia oryzae to the foliage application treatment.
一种利用杀真菌组合物的方法，其特征在于用有效量的组合物处理受试植物的种子或播种受试植物的栽培载体，该组合物含有从通式(I)代表的1,2,3-
噻二唑衍
生物及其盐中选出的一个或多个成员作为活性成分：
其中 R1 代表 H、(C1-6)烷基或 C3-7 环烷基，R2 代表 CO-Y-R3（其中 R3 代表 H、(卤代)(C1-20)烷基、(卤代)(C2-20)烯基、(取代)
氨基甲酰基(C1-6)烷基、(取代)苯基、(取代)苯基(C1-6)烷基、具有一个或多个选自 O、S 和 N 的杂原子的 5 至 6 元杂环等）。与叶面喷施处理相比，这种方法在控制病害伤害（如 Pyricularia oryzae）方面效果更佳。
