Compositions comprising, in an aqueous medium, (a) a water-soluble salt of glyphosate having water solubility such that the composition contains at least 50 g/l of glyphosate acid equivalent; (b) simazine, and (c) diuron as particulate solids substantially free from particles having sizes greater than 15 mu m; (d) a surfactant which is a non-ioinic block copolymer of propylene oxide and ethylene oxide, the central block of the molecule being poly(propylene oxide) and the end groups being poly(ethylene oxides), in an amount of from 2 to 15% of the combined weight of the simazine and diuron; e) a surfactant which is an ethoxylated C8-18 alkanoyl ester of sorbitan, in an amount of at least 40% of the combined weight of the simazine and diuron; f) a surfactant which is an ethoxylated fatty amine, in an amount of from 3 to 15% of the combined weights of surfactants (e) and (f); and (g) a water-soluble/water-dispersible thickener, in an amount such that the composition has a viscosity at 25 DEG C within the range 900 to 3500 cps; wherein the weight ratios of components (a) (expressed as glyphosate acid equivalent), (b) and (c) are from 1.0:0.4:0.5 to 1.0:3.0:3.5, have excellent long term storage stability. |
