PLANT DISEASE-PREVENTING AGENT COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a plant disease-preventing agent composition having synergistically enhanced action against a wide range of plant diseases such as downy mildew by including a thiophene derivative and a dithiocarbamate- based compound as active ingredients. SOLUTION: This composition is obtained by including (A) a substituted thiophene derivative shown by formula I [Q is H or the like; R is a 1-12C alkane or the like; Ar is formula II (R1 is trifluoromethyl or the like) e.g. N-[2-(1,3-dimethylbutyl)-3-thienyl]-2-chloronicotinic acid amide} and (B) a dithiocarbamate-based compound (e.g. zinc ethylenebisdithiocarbamate). It is preferable that the B/A weight ratio in the composition is 0.1-100.
