Composition and method for controlling plant diseases

摘要

The present invention provides a composition for controlling plant diseases having an excellent control efficacy on plant diseases. A composition for controlling plant diseases comprising an amide compound represented by a formula (I): wherein each of symbols are the same as defined in the Description; or salts thereof and one or more kinds of azole compounds selected from the group (A) consisting of tebuconazole, difenoconazole, triticonazole, imazalil, triadimenol, fluquinconazole, prochloraz, prothioconazole, diniconazole, diniconazole M, cyproconazole, tetraconazole, ipconazole, triforine, pyrifenox, fenarimol, nuarimol, oxpoconazole fumarate, pefurazoate, triflumizole, azaconazole, bitertanol, bromuconazole, epoxiconazole, fenbuconazole, flusilazole, flutriafol, hexaconazole, imibenconazole, myclobutanil, penconazole, propiconazole, simeconazole, triadimefon and metconazole, shows an excellent controlling efficacy on plant diseases.;

主权项

1. A composition for controlling plant diseases comprising an amide compound represented by a formula (I): wherein
n is 3 or 4;R1 represents a hydroxy group or a C1-C6 alkoxy group;R2 represents an optionally substituted phenyl group or an optionally substituted 3-indolyl group, and the phenyl group or the 3-indolyl group being represented by the R2 may be substituted on the carbon atoms independently of each other with one or more substituents selected from the group consisting of a halogen atom, a hydroxy group, a nitro group, a C1-C6 alkyl group or a C1-C6 alkoxy group; or salts thereof and at least one kind of azole compounds selected from the group consisting of tebuconazole, difenoconazole, triticonazole, imazalil, triadimenol, fluquinconazole, prochloraz, prothioconazole, diniconazole, diniconazole M, cyproconazole, tetraconazole, ipconazole, oxpoconazole fumarate, pefurazoate, triflumizole, azaconazole, bitertanol, bromuconazole, epoxiconazole, fenbuconazole, flusilazole, flutriafol, hexaconazole, imibenconazole, myclobutanil, penconazole, propiconazole, simeconazole, triadimefon and metconazole, and
wherein a weight ratio of the amide compound or salts thereof to the azole compounds is in the range of 100:1 to 10:1.
