Abstract: The invention relates to acetamides of the formula (III), ##STR1## wherein R.sup.1 stands for a halogenated alkyl group containing 1 to 2 carbon atoms, preferably for a dichloro- or dibromoalkyl group;R.sup.2 stands for a straight or branched alkyl group containing 1 to 6 carbon atoms or an alkenyl group containing 2 to 6, preferably 3, carbon atoms;R.sup.3 stands for an alkyl group containing 1 to 6, preferably 1 to 4, carbon atoms, an alkoxyalkyl group of altogether 2 to 6, suitably 4 carbon atoms, or a phenyl group;R.sup.3 and R.sup.4 together may stand for a propylene or butylene group;R.sup.4 and R.sup.5 stand independently from each other for hydrogen or a methyl group; andR.sup.4 and R.sup.5 together may stand for a propylene or butylene group.These compounds are antidotes and can be used along or together with herbicidal agents. The invention comprises such compositions and a process for the preparation of said compounds.

Abstract: 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; andR.sub.9 stands for hydrogen or a C.sub.1-4 alkyl group optionally substituted by halogen, or a phenyl group.

Abstract: The invention relates to compositions (extenders) useful for prolonging the action of herbicides containing thiolcarbamate derivatives as active ingredients as well as to herbicide compositions with a prolonged action containing thiolcarbamate derivatives as active ingredients and optionally an antidote which comprises a diaminomethane derivative of the general formula (III) ##STR1## wherein the R substituents stand independently from one another for C.sub.1-6 alkyl groups or for C.sub.2-4 alkenyl groups optionally substituted by a C.sub.1-4 alkyl group; and a process for prolonging the actin of herbicide compositions containing a thiolcarbamate derivative and optionally an antidote, which comprises applying the above mentioned composition in a quantity providing the prolonged action simultaneously with or after the application of the herbicide composition.
