摘要:

农药在保障农业生产、提高粮食产量和提高农民生活水平等方面发挥着重要作用。在农药防治病虫害的过程中,由于其活性成分理化性质不稳定和施药过程不合理导致有效成分易降解或流失,常规农药剂型有效利用率只有20%左右,同时存在有效成分释放速度快,药效持效时间短和环境条件影响大等问题。纳米农药控释剂作为当前农药剂型研究的热点,基于纳米分散制备技术和药物载体控制释放特性,将纳米技术和农药特性、防治对象、施药方式和环境条件等因素相结合,可以有效解决农药制剂活性成分损失严重和农药制剂有效利用率低等问题,使活性成分能够根据防治剂量的要求,在特定时间和空间范围内持续稳定的释放,以达到经济、安全、有效地控制病害虫。本研究综述了纳米生物材料应用于纳米农药控释剂研究进展,并对纳米农药控释剂的发展进行了展望。

Abstract:

Pesticides play an important role in ensuring agricultural production, increasing grain yield and improving farmers’ living standards. In the process of pesticide control of pests and diseases, the active ingredients are easily degraded or lost due to the unstable physicochemical properties of the pesticides’ active ingredients and the improper application process. The utilization rate of conventional pesticide formulations is only about 20%. At the same time, there are problems such as fast release rate of active ingredients, short duration of pesticide effect and great influence of environmental conditions. Controlled release nano-pesticide formulation is a hot spot in the research of pesticide formulations. Based on the nano-dispersion preparation technology and the slow and controlled release characteristics of pesticide carriers, the serious loss of active ingredients of pesticide can be solved by combining nanotechnology with pesticide characteristics, control target, application environment and application methods, so as to improve the effective utilization rate of pesticide formulations. The active ingredients can be released continuously and stably in a specific time and space according to the requirements of pest control dose, which has met the requirements of pest control economically, safely and effectively. In this study, the research progress of nano-biomaterials in controlled release nano-pesticide formulation was reviewed, and the application prospect of controlled release nano-pesticide formulation was discussed.
