Abstract
A solvent for producing emulsifiable concentrates from agriculturally active chemicals which are insoluble in water comprises an alkoxyalkyl lactam such as butoxy propyl pyrrolidone. An agriculturally active chemical and the alkoxyalkyl lactam are admixed optionally with co-solvents, emulsifiers and surfactants to produce a stable emulsifiable concentrate. The concentrate is dilutable with water at the point of use to produce either macro or micro emulsions which are themselves stable to assure even application.
