Liquid herbicidal compositions which consist of aqueous solutions containing a) N-phosphonomethylglycine (glyphosate; (HO)2 P(O)CH2NHCH2COOH) and/or one of its derivatives in a proportion of at least 40 g/l of glyphosate equivalent, and b) a surfactant of formula <IMAGE> [in which R is a C8-22 linear or branched, alkyl or alkenyl chain; A denotes an alkylene group; n, n' and n'' are integers such that n + n' + n'' is @between 1 and 15; and R<1> is hydrogen or an acyl radical] which has the nature @of a biological activator/herbicide. Incorporation of the above surfactant enables concentrated glyphosphate compositions to be formulated. |
