Description

一种农药喷雾专用增效剂及其制备方法与应用A special synergist for pesticide spraying and its preparation method and application

技术领域technical field

本发明涉及农药高效分散领域，具体是一种农药喷雾专用增效剂及其制备方法。The invention relates to the field of high-efficiency dispersion of pesticides, in particular to a special synergist for pesticide spraying and a preparation method thereof.

背景技术Background technique

目前，我国农作物病虫草害防治仍以喷雾防治为主，但在防治过程中，喷洒的农药仅20％至30％能沉积在靶标上，70％至80％流失或漂移到土壤、水体中，对农田生态乃至人类的生存环境造成严重污染。为保护生态环境及保障农产品质量安全，提高农药利用率和减少农药使用量已成为当前植保领域研究的重点和热点。在喷雾施药过程中，好的喷雾助剂的添加能有效降低农药药液的表面张力，优化雾滴粒径分布，提高雾滴在植物叶片上的粘附和润湿性能，从而显著提高雾滴在植物叶片上的沉积量，提高农药有效成分的利用率。但目前我国喷雾助剂产品相对较少，效果良莠不齐，导致应用不广。因此，有必要更多的开发效果显著的农药喷雾助剂产品投放市场，提高农药利用率，促进农药减量使用，减少环境污染，保障农产品质量安全。At present, the control of crop diseases, insect pests and weeds in my country is still dominated by spray control, but in the process of control, only 20% to 30% of the sprayed pesticides can be deposited on the target, and 70% to 80% are lost or drifted into the soil and water. It has caused serious pollution to farmland ecology and even the living environment of human beings. In order to protect the ecological environment and ensure the quality and safety of agricultural products, improving the utilization rate of pesticides and reducing the amount of pesticides used have become the focus and focus of current research in the field of plant protection. In the process of spray application, the addition of good spray auxiliaries can effectively reduce the surface tension of the pesticide liquid, optimize the particle size distribution of the spray droplets, and improve the adhesion and wetting performance of the spray droplets on the plant leaves, thereby significantly improving the spray efficiency. The amount of deposition on the leaves of plants can be increased, and the utilization rate of active ingredients of pesticides can be improved. However, at present, there are relatively few spray adjuvant products in my country, and the effects are uneven, resulting in their limited application. Therefore, it is necessary to put more pesticide spray adjuvant products with remarkable development effects on the market, improve the utilization rate of pesticides, promote the reduction of pesticide use, reduce environmental pollution, and ensure the quality and safety of agricultural products.

枯草菌脂肽钠是一种纯天然的表面活性剂,拥有独特的环状肽结构,从而得到了异常优异的乳化、分散等一系列表面活性性能。这一纯天然表面活性剂目前已经成功量产,并在化妆品、个人护理、洗涤等领域得到应用，但在农药领域应用还不多见。Sodium subtilisin is a pure natural surfactant with a unique cyclic peptide structure, thus obtaining a series of surface active properties such as exceptional emulsification and dispersion. This pure natural surfactant has been successfully mass-produced and has been applied in cosmetics, personal care, washing and other fields, but it is not widely used in the field of pesticides.
