Abstract
The present invention relates to liquid herbicidal agents in the form of emulsifiable concentrates (EC) or concentrated emulsions (EW), which, in addition to 1-40% by weight of the active compound diclofop-methyl (I), fenoxaprop-ethyl (II) or the optically active isomer (D+) thereof fenoxaprop-P-ethyl (III), contain, as surfactants, 0.5-30% by weight of (C.sub.10 -C.sub.18)-fatty alcohol polyglycol ethers or (C.sub.8 -C.sub.9)-alkylphenyl polyglycol ethers which are ethoxylated with 6-10 mol of ethylene oxide, and in the case of EC formulations 0.5-7% by weight of calcium (C.sub.8 -C.sub.14)-alkylbenzenesulfonate, and in the case of EW formulations, as a dispersing agent, 0.5-7% by weight of an ethylene oxide-propylene oxide-ethylene oxide block copolymer phosphorylated in the alpha- and omega-position, or a salt thereof, in addition to the customary formulation constituents. Compared with the known active compound formulations, these have significantly increased activities and improved mixing properties with water and other commercially available preparations containing active compounds.
