Abstract

Mercapto-bis-[1,3,4-oxa- and -thiadiazoles] ##STR1## in which X.sub.1 and X.sub.2 independently of one another are oxygen or sulfur, R.sub.1 is hydrogen or C.sub.1 -C.sub.5 alkyl which is unsubstituted or substituted by halogen, C.sub.1 -C.sub.3 alkoxy or cyano; C.sub.3 -C.sub.7 alkenyl which is unsubstituted or substituted by halogen; or C.sub.3 -C.sub.7 alkynyl which is unsubstituted or substituted by halogen, PA1 R.sup.2 is hydrogen, C.sub.1 -C.sub.5 alkyl, C.sub.1 -C.sub.3 alkoxy which is unsubstituted or substituted by halogen, C.sub.1 -C.sub.3 alkylthio which is unsubstituted or substituted by halogen, C.sub.3 -C.sub.7 alkenylthio which is unsubstituted or substituted by halogen, C.sub.3 -C.sub.7 alkylnylthio which is unsubstituted or substituted by halogen, --SH, phenyl which is unsubstituted or substituted by halogen or ##STR2## in which R.sub.3 and R.sub.4 are C.sub.1 -C.sub.3 alkyl, and processes for the preparation of the compounds of the formula I are described. The compounds of the formula I have nematocidal and microbicidal properties. Nematocidal compositions which contain at least one active substance of the formula I as the active substance and furthermore processe…
