The invention relates to compositions useful for prolonging the action and increasing the selectivity of herbicide compositions containing .alpha.-chloroacetamide derivatives as active ingredient as well as to highly selective herbicide compositions containing .alpha.-chloroacetamide derivatives as active ingredients and optionally an antidote wherein an animal derivative of the general formula (III) is used for achieving the prolonged action and increased selectivity. In the formula (III) ##STR1## R.sub.5, R.sub.6, R.sub.7 and R.sub.8 stand independently for hydrogen, a C.sub.1-6 alkyl, C.sub.3-7 cycloalkyl or C.sub.2-5 alkenyl group optionally substituted by a C.sub.1-4 alkyl group; and

Elective herbicide compositions having a prolonged action containing .alpha
