ABSTRACT:
A 1,2,4-oxadiazole derivative of the formula ##STR1## in which R.sub.1 and R.sub.2 are the same or different and are C.sub.1 -C.sub.8 -alkyl, C.sub.3 -C.sub.8 -cycloalkyl, halogeno-C.sub.1 -C.sub.3 -alkyl, phenyl, or phenyl substituted in one or several places by C.sub.1 -C.sub.4 alkyl, and/or C.sub.1 -C.sub.4 -alkoxy and/or trihalogenomethyl and/or halogen and/or cyano or are phenyl-C.sub.1 -C.sub.3 -alkyl, provided that at least one of R.sub.1 or R.sub.2 is constituted by the group ##STR2## in which R.sub.3 is C.sub.1 -C.sub.8 -alkyl, C.sub.3 -C.sub.8 -cycloalkyl, halogeno-C.sub.1 -C.sub.3 -alkyl, C.sub.1 -C.sub.6 -alkoxy, C.sub.1 -C.sub.4 -alkamino or di-C.sub.1 -C.sub.4 -alkamino. The compounds of the invention have a high activity against both mono- and di-cotyl weeds together with a high selectivity for agricultural plants such as rice, winter cereals, maize, cotton, sunflower, peanuts, soybeans, peas, alfalfa, clover and other leguminous plants.
