"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 are five alternative pesticides that ban pesticides. 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. There are two types of alternative pesticides for lepidopteran pests, such as Pieris rapae, Plutella xylostella, and soybean meal, in production: First, biopesticides, such as mothworms, quick killing, century lore, Peach Xiaoling, farmland music, etc.; Compound pesticides are commonly mixed as dichlorvos +bt, dichlorvos + kungfu, etc. The use of compound pesticides should pay attention to the prevention and treatment of insect pests in the low-invasion period, with good results; use of various types of insecticide rotation, and more use of biological pesticides to prevent pests produce resistance; now there are many contact pesticides, select pests during the feeding period The best effect, such as pods in the morning 6 to 8 climb out of the beans for food, this time the best effect of insecticide spraying. For the migratory pests such as yellow striped swiftlet and Huangshougua, the alternative pesticides are dichlorvos, farmland, and phoxim. When using, attention should be paid to a large area at the same time; Yellow flea beetles are used for a long time. In addition to spray prevention and control, underground larvae should be killed by means of irrigating the roots. Intermittent larvae are to be kept for 2 to 3 times in intervals of 5 to 7 days. The locusts and whitefly pests are easier to kill and can be promptly controlled by plutonium and dichlorvos. 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. Omethoate. Formerly used mainly for killing melons such as Puma, alternative pesticides such as Pluton, Dimethoate and so on. Carbofuran. Previously mainly applied to the 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. 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.
