It is inappropriate and inconsistent with the concept of sustainable agriculture and environmental protection to use highly toxic and highly residual pesticides to eliminate farmland pests. It will cause many harms to the environment, soil, water sources, beneficial organisms and agricultural product safety. It is recommended to give priority to green and environmentally friendly methods such as biological control and physical control to control pests. For example, use the natural enemies of pests to prey or parasitize, and set up insect-proof nets, insect-attracting lamps and other physical means to trap pests. If chemical agents must be used, high-efficiency, low-toxicity and low-residue pesticide varieties should be selected, such as biological pesticides such as Bacillus thuringiensis, spinosad, and matrine, as well as new and efficient chemical synthetic pesticides such as chlorantraniliprole, high-chlorofluoride, and cyanantraniliprole. At the same time, it is necessary to strictly follow the instructions for use and safety operating procedures of pesticides to avoid adverse effects on the ecological environment and human health. It is not recommended to use some highly toxic and potentially banned traditional pesticides at will.
