| abstract |
The invention relates to herbicidal compositions containing new PhenoxycarbonsÄure carbonylalkylestern. The aim of the invention is the provision of agents with improved herbicidal activity, broad spectrum of activity and good tolerability in crops. According to the invention, the new agents contain phenoxycarboxylic acid carbonylalkyl esters of the formula I in which R & exp1 !, R & exp2 !, R & exp3! and R & exp4! independently of one another represent hydrogen or alkyl. Furthermore, for example, R & exp5! Hydroxy, optionally substituted alkoxy, the radical (formula); R & Exp6! Hydrogen, optionally substituted alkyl, alkenyl, alkynyl, optionally substituted aryl; R & exp7! optionally substituted alkyl, optionally substituted aryl, alkenyl, alkynyl and the like; X is hydrogen or chlorine. |
