摘要:
N-(4-Pyrazolyl)amide derivatives of the general formula (I), exhibiting excellent control activities as bacteriocides, fungicides, insecticides, or nematicides for agricultural and horticultural use; chemicals for agricultural and horticultural use; and usage of the same, wherein R 1 is H, optionally halogenated (C 1 -C 6 )alkyl, optionally substituted phenylsulfonyl, optionally substituted phenyl, or the like; R 2 and R 3 are each H, halogeno, CN, NO 2 , OH, SH, NH 2 , optionally halogenated (C 1 -C 6 )alkyl, optionally substituted phenyl, or the like; R 4 is H, optionally halogenated (C 1 -C 6 )alkyl, cyano(C 1 -C 6 )alkyl, optionally substituted phenyl(C 1 -C 6 )alkyl, or the like; R 5 is a group of formula (a) or (b), optionally substituted naphthyl, or the like; and Y is (C 1 -C 6 )alkylene, optionally halogenated (C 1 -C 6 )alkyl(C 1 -C 6 )alkyl(C 1 -C 6 )alkylene, or the like.
摘要:
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 R 1 represents H, (C 1-6 )alkyl or C 3-7 cycloalkyl, and R 2 represents CO-Y-R 3 (wherein R 3 represents H, (halo)(C 1-20 )alkyl, (halo) (C 2-20 )alkenyl, (substituted) carbamoyl(C 1-6 )alkyl, (substituted) phenyl, (substituted) phenyl(C 1-6 )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.
