Abstract: In one aspect, this invention relates to a substantially water-insoluble pesticidal aggregate produced from a mixture comprising: (a) a polymer having at least three similarly charged electrostatic moieties; (b) an amphiphilic surfactant having at least one electrostatically charged moiety of opposite charge to the polymer; and (c) a pesticide. In other aspects, this invention relates pesticidal compositions comprising such a pesticidal aggregate and an agriculturally acceptable carrier, as well as to a method of controlling pests using such pesticidal compositions.

Abstract: An improved pesticide delivery system is disclosed. The system is based on a microblend comprising (a) an amphiphilic compound containing at least one hydrophilic group and at least one hydrophobic group and (b) a pesticide. Compositions based on the microblend and methods of using the compositions to control pests are also disclosed.
