A highly stable composition composed of a water insoluble agriculturally active ingredient, a surfactant, a lactam having formula (I) wherein R is hydrogen or a branched or straight-chained alkyl having from 1 to 16 carbon atoms, R1 is a branched or straight chained alkyl having from 1 to 16 carbon atoms, with the provision that the sum of the carbon atoms in R and R1 is less than or equal to 16; and n is 3, 4, or 5; and at least about 80 % by weight water, and wherein the specific agriculturally active ingredient, surfactant and lactam and amounts of each are such that the composition is in the form of a microemulsion. Also disclosed are microemulsion compositions which exhibit increased stability for agriculturally active ingredients which are subject to hydrolysis and microemulsion compositions which exhibit improved cold temperature stability. |
