Abstract: Fatty acid derivatives of the formula (I) wherein R1 is an aliphatic group containing 1 to 17 carbon atoms, which is linear, branched, saturated or unsaturated; R2, R3, R4, R5, R6, R7 are, independently, hydrogen, methyl, ethyl or hydroxymethyl; m, n and p are numbers from 0 to 17, with the proviso that m+n+p?1, and m+n+p<18 where the different monomers can be arranged in statistical order, alternatingly or as a block copolymer and m, n and p can be a statistical mixture; X is, independently, a covalent bond or hydroxy methylene; R8 is an aliphatic group containing 1 to 10 carbon atoms, which is linear, branched, cyclic, saturated or unsaturated, substituted or unsubstituted phenyl or substituted or unsubstituted benzyl, are useful as herbicides.

Abstract: The use of one or more fatty acid derivatives of the formula (I) wherein R1 is an alkyl group containing 5 to 17 carbon N atoms, which is linear or branched R2, R3 are, independently, hydrogen, methyl, ethyl or hydroxymethyl with the proviso that one of R2 and R3 is hydrogen and the other is different from hydrogen m, n are numbers from 0 to 17, with the proviso that m+n?1, and m+n+p<18 where the different monomers can be arranged in statistical order, alternatingly or as a block copolymer; R4 is hydrogen or an alkyl group containing 1 to 10 carbon atoms, which is linear or branched, can improve wettability, retention and/or the uptake of agrochemical actives in and on target organisms, wherein the agrochemical actives are different from the fatty acid derivatives of formula (I).

Abstract: A herbicide combination comprising an effective amount of components (A) and (B), where (A) denotes one or more fatty acid derivatives of the formula (I), wherein R1 is an alkyl group containing 5 to 17 carbon atoms, which is linear or branched R2, R3 are, independently, hydrogen, methyl, ethyl or hydroxymethyl with the proviso that one of R2 and R3 is hydrogen and the other is different from hydrogen m, n are numbers from 0 to 17, with the proviso that m+n?1 and m+n+p<18 where the different monomers can be arranged in statistical order, alternatingly or as a block copolymer, R4 is hydrogen or an alkyl group containing 1 to 10 carbon atoms, which is linear or branched, and (B) denotes one or more sulfonyl urea herbicides, is particularly suitable for controlling unwanted vegetation.
