摘要

A method of combatting phytopathogenic diseases on crop plants which comprises applying to the crop plants or the locus thereof being infested with said phytopathogenic disease an effective amount of a combination of: a) a 2-(5-phenyl-3,6-diaza-2,7-dioxa-octa-3,5-dienyl)-phenylacrylamide of formula (I) wherein R1 is hydrogen, fluoro or chloro, R2 is methyl, ethyl, trifluoromethyl, trifluoromethoxy, cyano, fluoro, chloro or bromo, with the proviso that R2 cannot be fluoro, chloro or bromo, when R1 is hydrogen; in association with b) a broad variety of other plant fungicides is particularly effective in combatting or preventing fungal diseases of crop plants.
