Abstract
The invention relates to new, fungicidally active pyrazole compounds of the general formula ##STR1## wherein Ar is an unsubstituted phenyl group or a phenyl group, substituted with 1 or 2 substituents selected from the group consisting of C.sub.1 -C.sub.4 alkyl, halogen, nitro, cyano and C.sub.1 -C.sub.4 alkoxy, or with 3 halogen atoms, R is a C.sub.1 -C.sub.12 alkyl group, R.sub.1 is a C.sub.1 -C.sub.4 alkyl group, and Y is CH or N. The invention also relates to new imidazolylvinyldithioacetals, suitable as starting materials for preparing said new pyrazole compounds and also having fungicidal activity.
Claims6
Pyrazole compound of the formula ##STR9## wherein Ar is an unsubstituted phenyl group or a phenyl group, substituted with 1 or 2 substituents selected from the group consisting of C.sub.1 -C.sub.4 alkyl, halogen, nitro, cyano and C.sub.1 -C.sub.4 alkoxy, or with 3 halogen atoms,
- R is a C.sub.1 -C.sub.12 alkyl group,
- R.sub.1 is a C.sub.1 -C.sub.4 alkyl group, and
- Y is CH or N.
A fungicidal composition characterized in that composition, in addition to a liquid or solid carrier material and, if desired, inert auxiliary substances selected from the group consisting of emulsifiers, wetting agents, dispersing agents and stabilizers has as active ingredient a fungicidally effective amount of a compound of the formula II, wherein Ar' is a phenyl group substituted with 1-3 halogen atoms, and R'.sub.1 is a C.sub.1 -C.sub.2 alkyl group.
