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 ##STR1## wherein X is oxygen, sulfur, --SO-- or --SO.sub.2 --, 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 C.sub.1 -C.sub.8 -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 C.sub.1 -C.sub.6 -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, --CH.sub.2 COOR or CH(CH.sub.3)COOR, wherein R is C.sub.1 -C.sub.3 -alkyl or allyl and R.sub.1 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.
一种用于保护文化植物免受除草活性氯乙酰胺类的光毒作用的组合物,其活性成分为式I的酰胺衍生物:##STR1## 其中X为氧、硫、--SO--或--SO.sub.2 --,Q为烷基、烯基、炔基,其中可以由氧、硫、亚砜或磺酰基中断,或为1,3-二氧杂环戊烷-2-基烷基、1,3-二氧杂环戊烷-4-烷基、2,2-二烷基-1,3-二氧杂环戊烷-4-基烷基、1,3-二氧杂环戊烷-2-基烷基、2-苯并吡喃基烷基、烷氧基羰基烯基氧羰基或四氢呋喃基烷基,或者OX基团还表示卤代烷基基团,n为1、2或3,Z为氢、卤素、烷基或二氧甲基,A为C.sub.1-C.sub.8-烃基,可以是直链、支链或环状的,未取代或被烷氧基、烷基硫、氰基或卤素取代,B为氢、C.sub.1-C.sub.6-烃基,可以是饱和或烯烃,取代或未取代,或B可以是环状烷基、烷基环状烷基、1,3-二氧杂环戊烷-2-基烷基、1,3-二氧杂环戊烷-4-基烷基、1,3-二氧杂环戊烷-2-基烷基、呋喃基烷基、四氢呋喃基烷基或者基团--NH--COOR、--CH.sub.2 COOR或CH(CH.sub.3)COOR,其中R为C.sub.1-C.sub.3-烷基或烯丙基,R.sub.1为卤代烷基或卤代烯基。其中一些化合物是新的,它们可以保护文化植物如谷物、玉米、小米和稻米免受氯乙酰胺类的光毒作用,而不会减少对杂草的除草作用。
