    Abstract: PROBLEM TO BE SOLVED: To obtain a liquid herbicide improved in low temperature-stability, herbicidal action and (rain) water resistance with a small addition amount of an organic solvent by making the herbicide contain a specific compound and a specific surfactant in a specific ratio. SOLUTION: This liquid herbicide is obtained by combining (A) a compound (a salt of a lower alkyl ester, an acid or a base) of the formula having a form of a racemic compound or an L-antipode with (B) a surfactant selected from a polyglycol ether sulfate of a 10-18C aliphatic alcohol, its alkali (alkaline earth) metal salt, its ammonium salt and its substituted alkyl- and alkanolamine salt in a weight ratio of (1:2)-(1:8), preferably (1:2)-(1:6.25), blending (C) a water miscible polar solvent (e.g. propylene glycol monomethyl ether) and, if needed, adding other surfactant, adhesive, binder, urea, inorganic salt, water soluble solvent, antifoaming agent, etc.

    Abstract: The present invention relates to liquid herbicidal agents in the form of emulsifiable concentrates (EC) or concentrated emulsion (EW), characterised in that they contain, besides 1 - 40% by weight of the active substance diclofop-methyl (I), fenoxaprop-ethyl (II) or its optically active isomer (D+) fenoxaprop-P-ethyl (III), 0.5 - 30% by weight of (C10-C18) fatty alcohol polyglycol ethers or (C8- C9)alkylphenyl polyglycol ethers which are 6 to 10 times ethoxylated as surfactants, and, in the case of EC formulations, 0.5 - 7% by weight of calcium (C18-C14)alkylbenzenesulphonate and, in the case of EW formulations, 0.5 - 7% by weight of an ethylene oxide/propylene oxide/ethylene oxide block copolymer which is phosphorylated in the alpha- and omega-position or a salt thereof as dispersant, besides the customary formulation components. Compared with the known active substance formulations, these agents have markedly increased activities and improved miscibility properties with water and with commercially available preparations containing other active substances.
