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, by applying a compound represented by formula (I) [wherein Q represents a group represented by the following Q1, Q2, Q3, Q4 or Q5 (in the formulae, ● represents a binding site to benzene ring); X represents an oxygen atom or NH; L represents CH2, an oxygen atom or NCH3; E represents a C6-C10 aryl group, etc.; R1 represents a C1-C3 chain hydrocarbon group or a cyclopropyl group, etc.; R2 represents a C1-C3 chain hydrocarbon group or a cyclopropyl group, etc.; R3 represents a C1-C3 alkoxy group or a C1-C3 chain hydrocarbon group, etc.; and n is 0, 1, 2, or 3] or its N oxide or an agriculturally acceptable salt thereof.

Description

TECHNICAL FIELD

[0001] This application claims priority to and the benefit of Japanese Patent Application No. 2018-143528 filed on Jul. 31, 2018, the entire contents of which are incorporated herein by reference.

[0002] The present invention relates to a method for controlling soybean rust fungus having an amino acid substitution of F129L on mitochondrial cytochrome b protein.BACKGROUND ART

[0003] The spread of phytopathogenic fungi that shows acquired character being resistant to agricultural fungicides becomes a major problem. Under such circumstances, FRAC (Fungicide Resistance Action Committee) has been established as an organization that provides guidelines for acquiring a resistance to existing agricultural fungicides, and suppressing and delaying the spread of the fungi having the resistance acquired. A variety of information on phytopathogenic fungi that shows a resistance to agricultural fungicides is available on the FRAC-provided website (http: / / www.frac.info / ). It has been kno...
