DCFirst Claim
1. A stable emulsifiable concentrate comprising an agriculturally active herbicide which is substantially insoluble in water, an organic diluent selected from the group consisting of soybean oil, rape seed oil, long-chain alcohols, long-chain ketones, long-chain esters, and ethers, and aromatic petroleum oils, a surfactant and a solvent composed of first and second components, said first component having a sufficiently high hydrophilic property and being present in an amount effective to solubilize the agriculturally active herbicide, and the second component being selected from the group consisting of octylpyrrolidone, dodecylpyrrolidone, N-2-ethylhexylpyrrolidone, and mixtures thereof, and being present in an amount, in conjunction with a surfactant, effective to disperse the agriculturally active herbicide.

Abstract
An emulsifiable concentrate comprising an agriculturally active chemical, a surfactant, an organic diluent and a solvent having first and second components, the first component being capable of solubilizing the agriculturally active chemical and the second component in conjunction with the surfactant being effective to disperse the agriculturally active chemical. The inventive concentrate allows for high concentrations of the active ingredient, exhibits excellent stability and produces highly stable compositions upon dilution with water.
