"Pollution-free" vegetable production is the trend of the times. The majority of vegetable growers have already had a profound understanding of this. However, five kinds of high-toxic and high-residue pesticides, such as methamidophos, which have been used by vegetable farmers for a long time, have been banned in technical regulations for the production of pollution-free vegetables. Here we introduce five alternative pesticides that are banned from pesticides and achieve equivalent control. One, methamidophos. Is a broad-spectrum insecticide, used to kill all kinds of pests before, but its highly toxic, residual period of 30 days or more, often caused by human and animal poisoning incidents, is the first banned pesticides pollution-free vegetable production. During production, attention should be paid to: 1. Lepidoptera pests such as Pieris rapae, Plutella xylostella, and soybean meal. There are two types of alternative pesticides: one is biological pesticides, such as mothworms, quick killing, centuries-killing, Tao Xiaoling, and farmland music; the second is the use of compound pesticides, the common compounding is dichlorvos + BT, dichlorvos + kungfu and so on. Use should pay attention to: 1 in the low insect pest spraying control, the effect is good; 2 rotation of various types of insecticides, more use of biological pesticides, to prevent pests produce resistance; 3 pesticides are now more than a contact effect, should choose pests foraging The period of spraying the best, such as pods in the morning 6:00 ~ 8:00 climbed out of the beans for food, this time the best effect of pesticide spraying. 2. For the yellow scoop swiftlet, Huang Shougua and other migratory pests. Alternative pesticides include dichlorvos, farmland, and phoxim. Use should pay attention to: 1 large area at the same time the prevention and control effect is good; 2 a lot of yellow scoop leaps, in addition to spray control, but also should be used to kill underground larvae; 3 intervals of 5 to 7 days, continuous control of 2 or 3 times . 3. Aphids, whitefly pests. Easier to kill, use plutonium, dichlorvos and other agents can be timely control. Second, dicofol. Previously used mainly to kill red spiders, crickets and so on. The alternative pesticides include insect glycosides, insect fleas, and ephedrine, which have significant effects after use. Third, omethoate. In the past, it was mainly used for killing melons, etc., and alternative pesticides such as plutonium and dimethoate. Fourth, carbofuran. Previously used mainly in soil to kill nematodes and other soil pests. Alternative pesticides include Miller, Enkeson and others. In addition, the same effect can also be achieved by using sun drying and liming. Five, methyl 1605. Previously widely used to kill various types of vegetable pests, such as troll leaf moth, alternative pesticides and methods of use similar to methamidophos. Vegetable production should strictly abide by the pollution-free operating procedures and prohibit the use of high-toxicity, high-residue pesticides. For pesticides that are allowed to be used, they must also strictly abide by the safety period regulations. By improving the level of pesticide application technology, it can meet the requirements of pollution-free vegetables and achieve high yield and quality.
