Abstract

The present invention provides a method for controlling a soybean rust fungus having an amino acid substitution of F129L on mitochondrial cytochrome b protein. According to the present invention, a compound represented by formula (I) [wherein R 1 represents a C1-C3 chain hydrocarbon group and so on, n is 0, 1, 2 or 3, and when is 2 or 3, a plural of R 2 may be identical to or different from each other, and R 2 represents a C1-C3 chain hydrocarbon group and so on, Q represents a group represented by Q1 (where • represents a binding site to a benzene ring) and so on, L 1 represents CH 2 or an oxygen atom, and E represents a C1-C6 alkyl group and so on.] can use to control a soybean rust fungus having an amino acid substitution of F129L on mitochondrial cytochrome b protein.
