A compound or salt thereof represented by the following general formula: (wherein, R 1 and R 2 represent a C 1 -C 6 alkyl group, aryl group, heteroaryl group, aralkyl group or R 1 and R 2 together represent a C 3 -C 10 cycloalkyl group, R 3 and R 4 represent a hydrogen atom, a C 1 -C 6 alkyl group or R 3 and R 4 together represent a C 3 -C 10 cycloalkyl group, R 5 represents a hydrogen atom, C 1 -C 6 alkyl group or acyl group, X represents a halogen atom, a C 1 -C 6 alkyl group, C 2 -C 6 alkenyl group, C 2 -C 6 alkynyl group, aryl group, heteroaryl group, C 1 -C 6 alkoxy group, amino group, acyl group, cyano group or N-hydroxyalkaneimidoyl group, Y represents a substituent selected from the group consisting of a halogen atom, C 1 -C 6 alkyl group, C 1 -C 6 alkoxy group and hydroxyl group, n represents an integer of 0 to 4, and m represents an integer of 0 to 6).
摘要:
Provided is a plant disease control composition that has a plurality of disease spectra against various plant pathogens and demonstrates superior control effects (synergistic control effects) that cannot be predicted from each component alone. The plant disease control composition comprises as active ingredients thereof at least one quinoline compounds represented by the following general formula: wherein, R 1 and R 2 represent, for example, optionally substituted alkyl groups or optionally substituted aryl groups, R 3 and R 4 represent, for example, hydrogen atoms, fluorine atom or methyl group, X represents, for example, a halogen atom or optionally substituted alkyl group, and Y represents a fluorine atom or methyl group, n is 0 to 2 and m is 0 or 1, or a salt thereof (group a), and one or more fungicidal compounds selected from group b.
