Abstract:
A method comprising applying a fungicide to a plant in need thereof, wherein the fungicide comprises a 4-quinolinol compound represented by the formula (I): or an agriculturally and horticulturally acceptable acid addition salt thereof, whereinR1 represents a hydrogen atom, an alkali metal, an alkaline earth metal, or COR4 in which R4 is a hydrogen atom, an optionally substituted C1-C18 alkyl group, an optionally substituted C2-C18 alkenyl group, an optionally substituted C3-C10 cycloalkyl group, an optionally substituted phenyl C1-C4 alkyl group, an optionally substituted phenoxy C1-C4 alkyl group, an optionally substituted aryl group, OR5 in which R5 is an optionally substituted C1-C4 alkyl group, an optionally substituted aryl group, an optionally substituted heterocycle, an optionally substituted phenyl C1-C4 alkyl group or an optionally substituted phenoxy C1-C4 alkyl group, or NR6R7 in which R6 and R7 are each a hydrogen atom, an optionally substituted C1-C6 alkyl group or an optionally substituted phenyl group, or R6 and R7 together with N may form a four- to six-membered ring containing one or two heteroatoms; R2 represents an optionally substituted lower alkyl group; R3 represents an optionally substituted C1-C18 alkyl group, an optionally substituted lower alkenyl group, or an optionally substituted lower alkoxy group; or R2 and R3 together represent â€”(CH2)mâ€” in which m is 3 or 4; and W represents 1 to 4 substituents on the nucleus which may be identical or different and each of which is a halogen atom, an optionally substituted C1-C10 alkyl group, an optionally substituted C2-C4 alkenyl group, an optionally substituted C2-C4 alkynyl group, an optionally substituted C1-C10 alkoxy group, an optionally substituted C3-C10 cycloalkyl group, an optionally substituted aryl group, an optionally substituted aryloxy group, NR8R9 in which R8 and R9 are each a hydrogen atom, an optionally substituted C1-C6 alkyl group or an optionally substituted phenyl group, or R8 and R9 together with N may form a four- to six-membered ring containing one or two heteroatoms, COR10 in which R10 is a hydrogen atom, an optionally substituted C1-C4 alkyl group or an optionally substituted C2-C4 alkenyl group, COOR11 in which R11 is a hydrogen atom, an optionally substituted C1-C4 alkyl group or an optionally substituted C2-C4 alkenyl group, a nitro group, or a cyano group; wherein when optional substituents present, the optional group is selected from the group consisting of halogen, C1-C4 alkyl group, C1-C4 alkoxy group, hydroxyl, nitro, formyl, and cyano.
