Tropical and temperate crops, particularly rice, maize, cotton, soya and fruit, can be protected, particularly against insect pests of the orders Lepidoptera, Diptera, Coleoptera, Hemiptera, Orthoptera, Dictyoptera, Hymenoptera and Isoptera and acarine pests, by treatment with a pesticidal water-miscible formulation whose average particle size is at most 200 nm. Public health pests, including the house fly (Musca domestica), cockroach (Blatta or Periplaneta sp.) and mosquito (Aedes aegypti) as well as pests which infest or affect timber, particularly in buildings, can also be controlled with such formulations. The formulations include water, oil, a surfactant, and a cosurfactant, wherein either the oil is a pesticide or the formulation comprises 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. |
