## Abstract

A fungicidal composition is provided. A fungicidal composition comprising synergistically effective amounts of (a) a carboxylic acid amide derivative of the formula (I) or its salt: wherein B is a heterocyclic group which may be substituted; each of R1 and R2 which are independent of each other, is alkyl; X is halogen, alkyl or alkoxy; and n is an integer of from 0 to 5, and (b) at least one fungicidal compound selected from the group consisting of an azole compound, an anilinopyrimidine compound, a triazolopyrimidine compound, a strobilurin compound, an N-halogenothioalkyl compound, a pyridinamine compound, a bicarbonate, an inorganic sulfur compound, a dithiocarbamate compound, an organic chlorine compound, a dicarboxyimide compound, an amine compound, a phenylpyrrole compound, a benzophenone compound, a dinitrobenzene compound, a piperidine compound, a morpholine compound, etc.

## Claims

### Claim 1

A fungicidal composition comprising synergistically effective amounts of:
(a) N-[[2′-methyl-4′-(2-propyloxy)-1,1-dimethyl]phenacyl]-3-methyl-2-thiophenecarboxamide as a carboxylic acid amide derivative; and
(b) at least one fungicidal compound selected from the group consisting of ferimzone, 5-chloro-7-(4-methylpiperidin-1-yl)-6-(2,4,6-trifluorophenyl)-[1,2,4]triazolo[1,5-a]pyrimidine, potassium bicarbonate, sulfur, meptyldinocap, potassium phosphite, copper oxychloride, kasugamycin, 2,3-dimethyl-6-t-butyl-8-fluoro-4-acetylquinoline, 2-(2-fluoro-5-(trifluoromethyl)phenylthio)-2-(3-(2-methoxyphenyl)thiazolidin-2-yliden)acetonitrile, 4-(2,3,4-trimethoxy-6-methylbenzoyl)-2,5-dichloro-3-trifluoromethylpyridine, 4-(2,3,4-trimethoxy-6-methylbenzoyl)-2-chloro-3-trifluoromethyl-5-methoxypyridine, 3-(2,3,4-trimethoxy-6-methylbenzoyl)-5-bromo-4-chloro-2-methoxypyridine, 3-(2,3,4-trimethoxy-6-methylbenzoyl)-5-chloro-2-methoxy-4-methylpyridine, bixafen, fluopyram, and isopyrazam;
wherein the blend weight ratio of (a) to (b) is from 1:1000 to 2083:1.

### Claim 2 (depends on 1)

A method for controlling noxious fungi, which comprises applying the composition as defined in claim 1 to noxious fungi or to a site where noxious fungi grow.

### Claim 3 (depends on 1)

A method for controlling noxious fungi, which comprises applying (a) the carboxylic acid amide derivative, and applying (b) the fungicidal compound, as defined in claim 1, to noxious fungi or to a site where noxious fungi grow.
