PLANT DISEASE CONTROL COMPOSITION AND METHOD FOR CONTROLLING PLANT DISEASE BY APPLICATION OF SAME

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, R1 and R2 represent, for example, optionally substituted alkyl groups or optionally substituted aryl groups, R3 and R4 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.
