<p>Water-miscible pesticidal formulations whose average particle size is at most 200 nm include water, oil, a surfactant, and a cosurfactant, which comprises a wetting agent such as a polysiloxane-based copolymer such as a polysiloxane-polyether copolymer. Such formulations have particular application in the delivery of pesticides such as insecticides and acaricides, and therefore either the oil may be a pesticide or the formulation may comprise a pesticide dissolved in the oil. The pesticide may be a pyrethroid such as cypermethrin or deltamethrin. The formulations can be molecular solutions, micellar solutions or microemulsions (water-in-oil or oil-in-water) and are generally clear.</p> |
