ABSTRACT:
2-Mercapto-1,3,4-oxadiazoles and 2-mercapto-1,3,4-thiadiazoles of the formula I ##STR1## in which X.sub.1 and X.sub.2 independently of one another are oxygen or sulfur, R.sub.1 is difluoromethyl or 3,4,4-trifluoro-3-butenyl, R.sub.2 is hydrogen or C.sub.1 -C.sub.3 alkyl and R.sub.3 is hydrogen, C.sub.1 -C.sub.5 alkyl which is unsubstituted or substituted by halogen or C.sub.1 -C.sub.3 alkoxy, C.sub.3 -C.sub.7 alkenyl which is unsubstituted or substituted by halogen or C.sub.1 -C.sub.3 alkoxy, C.sub.3 -C.sub.7 alkynyl which is unsubstituted or substituted by halogen or C.sub.1 -C.sub.3 alkoxy, or phenyl which is unsubstituted or substituted by halogen, NO.sub.2, CF.sub.3, C.sub.1 -C.sub.3 -alkyl or C.sub.1 -C.sub.3 alkoxy, or wherein, furthermore, R.sub.2 and R.sub.3 together can form the methylene chain (--CH.sub.2 --)n as a constituent of a 5- or 6-membered ring with the heteroatom X.sub.1, in which n is 3 or 4, and processes for the preparation of the compounds of the formula I are described.
The compounds of the formula I have nematicidal properties. Nematicidal compositions which contain at least one active substance of the formula I as the active substance and furthermore methods of using the active substances and the compositions for controlling nematodes are described.
