The invention belongs to the technical field of pesticides, and discloses a chlorpyrifos-containing nano-aqueous preparation. The nano-aqueous preparation uses the original chlorpyrifos drug, a surfactant and water as raw materials, does not contain any organic solvent, and adopts the surfactant micelle solubilization technology. wherein, the mass percentage of the nano-aqueous agent chlorpyrifos is 0.5-10%, the mass percentage of the surfactant is 5-20%, and the balance is water. Compared with the conventional pesticide formulations, the invention adopts the surfactant micellar solubilization technology to prepare the nano-aqueous formulation, which has excellent stability, and is still stable after 7 days of cold storage at 0 °C and 14 days of hot storage at 54 °C, and chlorpyrifos will not Precipitation is convenient for storage, and the shelf life is longer; the nano-water preparation of the invention has lower production cost, better quick-acting and lasting effect, no adverse reactions such as phytotoxicity, and is more suitable for drone medication. |
