ABSTRACT:
Novel isoxazolyl-alkyl thiolcarbamates and novel herbicidal compositions containing the novel thiolcarbamates are disclosed wherein the thiolcarbamates are of the formula: ##STR1## in which R.sub.1 and R.sub.2 are identical or different and each represents a hydrogen atom, a linear or branched alkyl radical containing 1 to 6 carbon atoms, a cycloalkyl radical containing 3 to 6 carbon atoms, an alkenyl radical containing 2 to 4 carbon atoms, an alkoxy radical containing 1 to 6 carbon atoms, an alkoxyalkyl radical in which each alkyl part contains 1 to 4 carbon atoms, an optionally substituted aryl radical, an optionally substituted aralkyl radical in which the alkyl part contains 1 to 4 carbon atoms, or a saturated or unsaturated heterocyclic radical which has 5 to 6 chain members and contains, as the hetero-atom, an oxygen, nitrogen or sulphur atom, or R.sub.1 and R.sub.2 together with the nitrogen atom to which they are bonded form a saturated or unsaturated, optionally substituted heterocyclic structure which has 5 to 6 chain members and can contain, as a hetero-atom, an oxygen atom in addition to the nitrogen atom, R.sub.3 represents a hydrogen atom or an alkyl radical containing 1 to 4 carbon atoms and Y and Y' are identical or different and each represents a hydrogen or halogen atom, an alkyl radical containing 1 to 6 carbon atoms, a trifluoromethyl radical or an optionally substituted aryl radical. The new thiolcarbamates are useful in the form of herbicidal compositions for the selective destruction of weeds in crops of maize, groundnuts, rape, cotton, soya, beans, sunflowers, wheat and rice.
