Abstract
It has now been found that the use of: A) a N-sulfonyl-valine-amide of formula (I) wherein R1 is hydrogen, C1-4 alkyl, C3-6cycloalkyl or halophenyl, and R2 is C1-4 alkyl; in association with B) either compounds of formulae II to XII is particularly effective in combating or preventing fungal diseases of crop plants. These combinations exhibit synergistic fungicidal activity. Prominent examples for the compounds of formulae II to XII are: acibenzolar-S-methyl, azoxystrobin, chlorothalonil, cymoxanil, dimethomorph, fluazinam, fludioxonil, imazalil, S-imazalil, mancozeb, metalaxyl, metalaxyl-M, picoxystrobin, pyraclostrobin (BAS 500F) and trifloxystrobin.
