Abstract:
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 compound of formula I compound of formula I wherein R is hydrogen or methoxy; Q is R1 is hydrogen, halogen or C1-C6alkyl; R2 is hydrogen, halogen, C1-C6alkyl, C2-C6alkenyl, C3-C6alkinyl, C3-C6cycloalkyl-C3-C6alkinyl, halophenoxy, halophenyl-C3-C6alkinyl, C(C1-C4alkyl)═NO—C1-C4alkyl, C1-C6haloalkyl, C1-C6haloalkoxy, C2-C6haloalkenyl, or C2-C6haloalkenyloxy; R3 is hydrogen, halogen, C1-C6alkyl; R4, R5 and R6, independently from each other, are hydrogen, halogen or -≡-R7; with the proviso that at least one of R4, R5 and R6 is different from hydrogen; R7 is hydrogen, C1-C6alkyl, C1-C6haloalkyl or C1-C4alkoxyalkyl; and R8 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.
Abstract:
The invention relates to a process for the preparation of a compound of formula (I), wherein R1, R2 and R3 are as defined in claim 1, which process comprises a) adding a compound of formula (II), in the presence of an inert organic solvent to a mixture comprising an organic nitrite of formula (III) (R4—O—N═O (III)), wherein R4 is C1-C8alkyl, a compound of formula (IV), and an inert organic solvent; b) reacting the resulting compound of formula (V), with H2N—O—CH3 to the compound of formula (VII), c) reducing the compound of formula (VII) to the compound of formula (VIII), d) and reacting the compound of formula VIII with a compound of formula (IX), in which R* is halogen, hydroxy or C1-6 alkoxy, to the compound of formula (I).
