Fungicidal compositions
A composition suitable for control of diseases caused by phytopathogens comprising a mixture of a compound of formula I with two compounds selected from compounds known for their fungicidal activity; and a method of controlling diseases on useful plants.
1. A composition suitable for control of diseases caused by phytopathogens comprising:
(A) 3-(difluoromethyl)-N-methoxy-1-methyl-N-[1-methyl-2-(2,4,6-trichlorophenyl)ethyl]pyrazole-4-carboxamide;
(B) the compound of formula VII
