fungicidal compositions. The present invention relates to a method of controlling plant pathogenic diseases in useful plants or their propagation material, which comprises applying a combination of components (a) and (b) to the useful plants, their site or their propagation material. in a synergistically effective amount wherein component (a) is a compound of formula (i) compound of formula (i) wherein r is hydrogen or methoxy; q is R1 is hydrogen, halogen or C1-6 alkyl; R2 is hydrogen, halogen, C1-6 alkyl, C1-2-C6 alkenyl, C3-6 C6 alkynyl, C3-6 C 3-6 cycloalkyl-alkynyl, halophenoxy, halophenyl-C 3-6 C-alkynyl, C (C 1-4 C-4 alkyl) = non-C 1-1 C 1-4 alkyl, C 1-1 -C 6 haloalkyl, C 1-1 C 6 haloalkoxy, C 2-6 C 6 haloalkyl, or C 2-6 C 6 haloalkenyloxy ; R3 is hydrogen, halogen, C1-6 alkyl; r ~ 4 ~, r ~ 5 ~, and r ~ 6 ~, independently of each other, are hydrogen, halogen or <sym> r ~ 7 ~; provided that at least one of r ~ 4, r ~ 5 ~ and r ~ 6 ~ is other than hydrogen; R 7 is hydrogen, C 1-6 alkyl, C 1-6 haloalkyl or C 1-4 alkoxyalkyl; and R8 is hydrogen or methoxy; and agriculturally acceptable salts / isomers / structural isomers / stereoisomers / diastereoisomers / enantiomers / tautomers and n-oxides of such compounds; and component (b) is a compound selected from known compounds for their fungicidal and / or insecticidal activity, is particularly effective in controlling or preventing useful plant fungal diseases. |
