The above emulsifier system may be dissolved in a polar solvent such as dimethyl formamide, dimethylacetamide, N-methylpyrrolidone, a C 3-8 alcohol or a mixture thereof. Specified plant protection agents are isobutyl 2,4-dichlorophenoxyacetate, toxaphene malathain and methyl and ethyl parathion, and these are preferably mixed with 2 to 15% by weight of the emulsifier system or a 20 to 85% by weight solution thereof in a polar solvent. The resulting plant protection compositions may be diluted with water prior to use.
