METHOD FOR CONTROLLING PLANT DISEASES

Abstract

The present invention provides a method for controlling a plant disease comprising applying a compound represented by formula (I) wherein n is 0, 1, or 2, R1 represents a C1-C6 ialkyl group, etc., R2 and R3 are identical or different from each other and each represents a C1-C6 chain hydrocarbon group that may be optionally substituted with one or more halogen atoms, etc., R4 represents a C1-C6 chain hydrocarbon group, etc., q is 1, 2, or 3, and when q is 2 or 3, 2 or 3 of R4 are identical or different from each other, a combination of X1, X2, X3, and X4 represents a combination wherein X1 represents CR5, X2 represents CR6, X3 represents CR7, and X4 represents a nitrogen atom, etc., and R5, R6, and R7 are identical or different from each other and each represents a C1-C6 chain hydrocarbon group that may be optionally substituted with one or more halogen atoms, etc.] or the N-oxide thereof, or the salt thereof, to a plant or to the soil for growing the plant, which has excellent control efficacies against plant diseases.
