Pesticides with high toxicity and residue in vegetable production are mostly pesticides. In order to use less or no chemical pesticides, people have adopted many "non-pesticide plant protection technologies" to control pests and achieved good results. The most used one is "five ones".

"Yi Deng": i.e. frequency vibrating insecticidal lamp. It is mainly used to kill adults of "big bugs" such as Spodoptera litura, Spodoptera argentea, Spodoptera brassicae and cutworms. Generally, installing one lamp in 2 ~ 3.33 hectares can effectively control the harm of such pests. Small investment, great effect and wide application.

"One net": insect net, mainly used for pest control in greenhouses and other facilities. Although the investment is relatively large, it has a good control effect on "big bugs" and "small bugs", especially in the peak period of insect pests, and it is better to produce leafy vegetables.

"One board": plywood, with yellow board and green board. Yellow board is mainly used to trap and kill aphids, whiteflies and flies; Green board is mainly used to trap and kill thrips and other pests.

"One core": bait. At present, many attractants, including sex attractants and other odor attractants, have been developed in the market to make various lures, and it is also very effective to trap and kill pests with lures.

"One-board worm": the natural enemy of pests, such as using Trichogramma to control many LEPIDOPTERA pests; Using predatory mites to control tea yellow mites on eggplant and pepper is effective.
