A composition of matter and method of making the composition which relates to an all aqueous, phase stable emulsion of organophosphorous pesticides which is free of organic solvents. The composition comprises from about 40 to 95 percent by weight of an organophosphorous selected from the group consisting of phosphates, phosphorothioates and phosphorothionates, and mixtures thereof, from about 3 to 10 percent by weight of a nonionic block, heteric, heteric/block copolymer of ethylene oxide and propylene oxide, from about 3 to 16 percent by weight urea, and about 20 to 50 percent water. The composition is made by blending these components together under moderate agitation.
