The “no pollution†of vegetable production is the trend of the times, and the majority of vegetable farmers have a deep understanding of this. However, five kinds of highly toxic and high-residue pesticides, such as methamidophos, which have been used by vegetable farmers for a long time, have been banned in the technical regulations for the production of pollution-free vegetables. Here are five alternative pesticides that are banned.
Methamidophos. It is a broad-spectrum insecticide. It used to be used to kill all kinds of pests, but its high toxicity, residual period of more than 30 days, often causing poisoning incidents of humans and animals, is the primary banned pesticide in pollution-free vegetable production. There are two types of alternative pesticides for Lepidoptera pests such as Pieris rapae, Plutella xylostella, and pea pods in production: one is biological pesticides, such as moth sorghum, century lore, peach xiaoling, farmland music, etc.; Compound pesticides, common compounding is dichlorvos + bt, dichlorvos + kung fu. The use of compound pesticides should pay attention to the prevention and control of pesticides in the low age of the pests, and the effect is good; the use of various pesticides in rotation, and the use of biological pesticides to prevent the pests from developing resistance; now the pesticides have a contact effect, and the pests are selected for spraying during the feeding period. The best effect, such as the pea pods crawling out of the pods for food at 6-8 in the morning, the best effect of spraying and killing insects. For migratory pests such as yellow stripe and yellow squash, the alternative pesticides include dichlorvos, agricultural land, and phoxim. When using, pay attention to large area and control effect at the same time; when the number of yellow stripe jumpers is large, in addition to spray control, root larvae should be killed by root irrigation; interval 5~7 days, continuous prevention and control 2~3 times. It is easy to kill aphids and whitefly mites, and it can be controlled in time with cockroaches and dichlorvos.
Triclosan. Previously used to kill red spiders, mites and so on. The alternative pesticides are insects, worms, worms, etc., and the effect is obvious after use.
Omethoate. In the past, it was mainly used to kill melons such as melons.
Carbofuran. Previously applied to the soil to kill nematodes and other soil pests. Alternative pesticides include Miller and Dixon. In addition, the same effect can be achieved by using the method of turning the soil and applying lime.
Methyl 1605. Previously used to kill a variety of vegetable pests, such as the tick moth, alternative pesticides and methods of use similar to methamidophos.
Vegetable production should strictly abide by pollution-free operating procedures, ban high-toxic, high-residue pesticides, and must strictly comply with the safety period for pesticides that are allowed to be used. By improving the level of pesticide application technology, it not only meets the requirements of pollution-free vegetables, but also achieves the goal of high yield and high quality.
