A method of controlling phytopathogenic diseases on useful plants or on propagation material thereof, which comprises applying to the useful plants, the locus thereof or propagation material thereof a combination of components (A) and (B) in a synergistically effective amount, wherein component (A) is a com pound of formula (I) compound of formula (I) wherein R is hydrogen or methoxy Q is (Qi) or (Q2) Riis hydrogen, halogen or CiC6alkyl R2 is hydrogen, halogen, CiC alkyl, C2-C alkenyl, -C alkinyl, -C cycloalkyl - C alkinyl, halophenoxy, halophenyl-C -C alkinyl, C(Ci-C4alkyl)=NO-Ci-C alkyl, CiC haloalkyl CiC6haloalkoxy, C2-C6haloalkenyl, or C2-C6haloalkenyloxy is hydrogen, halo gen, CiC6alkyl R4, and independently from each other, are hydrogen, halo gen or with the proviso that at least one of R4, and is different from hydrogen R7 is hydrogen, CiC6alkyl, CiCehaloalkyl or CiC4alkoxyalkyl and Rs is hydrogen or methoxy and agrochemically acceptable salts/isomers/structural isomers/ stereoisomers/diastereoisomers/enantiomers/tautomers and N-oxides of those compounds and component (B) is a compound selected from compounds known for their fungicidal and/or insecticidal activity, is particularly effective in controlling or preventing fungal diseases of useful plants.
