Nematicidal and fungicidal compositions Abstract of the Disclosure 2-Mercapto-5-thiazol-(2-, 4- or 5-yl)-1,3,4-oxa- and -thia-diazoles and 2-mercapto-5-oxa- zol-(2-, 4- or 5-yl)-1,3,4-oxa- and -thia-diazoles of formula I Image (I) wherein X1 and X2 independently of one another are oxygen or sulfur, R1 is unsubstituted C1-C5alkyl or C1-C5alkyl substituted by halogen, C1-C3alkoxy or by cyano; unsubstituted or halo-substituted C3-C7alkenyl; or unsubstituted or halo-substituted C3-C7alkynyl, R2 and R3 independently of one another are hydrogen, C1-C5alkyl, unsubstituted or halo-sub- stituted C3-C7alkenyl, unsubstituted phenyl or phenyl substituted by identical or different substituents selected from C1-C3alkyl, C1-C3alkoxy and halogen, or the radical -NR4R5 wherein R4 and R5 independently of one another are hydrogen, C1-C5alkyl or unsubsti- tuted or halo-substituted C3-C7alkenyl, or one of the two substituents R2 and R3 may be one of the unsubstituted or substituted heterocycles pyridyl, thienyl, furyl and thiazolyl, a process for the preparation of the compounds of formula I, and novel intermediates of the preparation process are described. The compounds of formula I possess nematicidal and fungicidal properties. Nematicidal and fungicidal compositions that contain at least one compound of formula I as active ingredient, and also methods of using the active ingredients and the compositions in the control of nematodes and fungi, are described.
