Abstract

The invention belongs to the technical field of pesticides, and discloses a beta-cypermethrin nano water agent, which is prepared by taking beta-cypermethrin, a surfactant and water as raw materials,does not contain any organic solvents, and is prepared by adopting a surfactant micelle solubilizing method, wherein the mass percentage content of the beta-cypermethrin in the nano aqueous agent is 0.5-5%, the mass percentage content of the surfactant is 5-25%, and the balance is water. According to the invention, the nano water agent is prepared by adopting a surfactant micelle solubilizing technology, has excellent stability compared with the conventional pesticide dosage forms, is still stable after being stored for 7 days at a temperature of 0 DEG C and stored for 14 days at a temperatureof 54 DEG C, cannot precipitate beta-cypermethrin, is convenient to store, long in shelf life, low in production cost and excellent fast-acting property and persistence, does not have adverse reactions such as phytotoxicity and the like, and is suitable for unmanned aerial vehicles to use.
