Abstract

The invention belongs to the technical field of pesticide preparations, and provides a nano pesticide composite preparation based on phosphate and metal ions and a preparation method of the nano pesticide composite preparation. A pesticide raw material solution, a metal ion solution and a phosphate solution are mixed and subjected to one-step coprecipitation to synthesize a nano-composite preparation, pesticide molecules are embedded in nano-particles, and the pesticide nano-composite preparation is synthesized through the reaction processes of washing, drying and the like. A buffer system formed by phosphate can improve the pH-resistant stability of the pesticide raw material. Through the embedding method, the immobilization amount of the pesticide is effectively increased, and the release of the pesticide can be effectively controlled. Moreover, the phosphate-pesticide nano composite preparation provided by the invention is relatively low in preparation cost and convenient to transport and store.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparations, and in particular relates to a nano-pesticide composite preparation based on phosphate and metal ions and a preparation method thereof. Background technique [0002] Pesticides can reduce the annual losses caused by diseases, insects and other pests in the world's agriculture. However, the use of pesticides will also bring some negative effects, such as: certain harm to the human body, pollution to soil, water, and the atmosphere. Although pesticide raw materials can be prepared into various dosage forms by technical means to reduce the adverse effects of pesticide raw materials, some additives and organic solvents are usually used in the preparation of traditional pesticide dosage forms, which makes the effective utilization of pesticides low, and also Thus causing a series of environmental pollution. [0003] With the rapid development of nanotechnology, nanomaterials are wid...
