Fungicidal mixture and use thereof

摘要

Fungicidal mixtures, comprising A) imidazole derivatives of the formula I in which R¹ and R² are halogen or phenyl, which may be substituted by halogen or alkyl, or R¹ and R² together with the bridging C-C double bond form a 3,4-difluoromethylenedioxyphenyl group; R³ is cyano or halogen, and R⁴ is dialkylamino or isoxazol-4-yl, which may carry two alkyl radicals; and B) valinamides of the formula II, in which R' is phenyl, which is substituted in the 4-position by halogen, C₁-C₄-alkyl or C₁-C₄-alkoxy, is 1- or 2-naphthyl, or is benzothiazol-2-yl, which is substituted in the 6-position by halogen; and R'' is C₃-C₄-alkyl; in a synergistically effective amount, methods for controlling harmful fungi using mixtures of the compounds I and II and the use of the compounds I and the compounds II for preparing such mixtures are described.
