Abstract
Stable, aqueous emulsion formulations of water-insoluble organic pesticides are formed from a mixture of (1) a water-insoluble organic pesticide, (2) a water based structured particle latex containing nonionic particles to which is bound a layer containing stabilizing pH independent ionic groups chemically bound at or near the surface of the polymer particles, and optionally a cosolvent and/or cosurfactant for the pesticide. The resulting product is much more stable to coalescence than emulsions made with conventional surfactants.
