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.
