A composition for protecting culture plants from the phytotoxic action of herbicidally active chloracetanilides contains as active ingredient an acylamine derivative of the formula I <IMAGE> wherein X is oxygen, sulfur, -SO- or -SO2-, Q is an alkyl, alkenyl, alkinyl group, which may be interupted by oxygen, sulfur, sulfinyl or sulfonyul, or a test 1,3-dioxolan-2-yl-alkyl, 1,3-dioxolan-4-alkyl, 2,2-dialkyl-1,3-dioxolan-4-ylalkyl, 1,3-dioxan-2-ylalkyl, 2-benzopyranylalkyl, alkoxycarbonyl alkenyl-oxycarbonyl or tetrahydrofurylalkyl, or the group OX represents also a halogenoalkyl radical, n is 1, 2 or 3, Z is hydrogen, halogen, alkyl or dioxymethylene, A is a C1-C8 -hydrocarbon radical which may be staight-chained, branched or cyclic and which is unsubstituted or substituted by alkoxy, alkylthio, cyano or halogen, B is hydrogen, a C1-C6-hydrocarbon radical which may be saturated or olefinic, substituted or unsubstituted or B may be cycloalkyl, alkylcycloalkyl, 1,3-dioxolan-2-ylalkyl, 1,3-dioxolan-4-ylalkyl, 1,3-dioxan-2-ylalkyl, furylalkyl, tetrahydrofurylalkyl or a radical -NH-COOR, -CH2COOR or CH(CH3)COOR, wherein R is C1-C3-alkyl or allyl and R1 is halogenoalky or halogenoalkenyl. Some of these compounds are new. They protect culture plants such as cereal, maize, millet and rice from the phytotoxic action of the chloracetanilide without reducing the herbicidal action on the weeds. |
