3-(ISOQUINOLINE-1-YL)QUINOLINE DERIVATIVE

摘要

It is intended to provide a 3-(isoquinoline-1-yl)quinoline derivative (I), a salt thereof and an agrochemical composition containing the same as an active ingredient, particularly an agricultural and horticultural bactericide that shows an excellent effect on a variety of plant pathogens (particularly for rice blast) without causing damage to a host plant. The 3-(isoquinoline-1-yl)quinoline derivative (I) represented by the formula: (I) (wherein the ring A and the ring B: a benzene ring or the like, R<SUP>1</SUP> to R<SUP>4</SUP>: H, halogen, alkyl, OH, an alkoxy group or the like, Q: N, N-R<SUP>5</SUP> (R<SUP>5</SUP>: H, OH, an alkyl group or the like), X: halogen, alkyl or the like, Y: halogen, an alkyl group or the like, n: 0 to 4, m: 0 to 6, a bond including a dotted line: a single bond or a double bond) or a salt thereof.
