With the impact of pesticides on the environment and human health, a number of pesticides have been banned. The pesticides have been compiled into five banned pesticides and derived substitutes:
Methamidophos
It is a broad-spectrum insecticide . It used to be used to kill all kinds of pests. However, it is highly toxic and has a residual period of more than 30 days. It often causes poisoning of humans and animals and is the primary banned pesticide in the production of pollution-free vegetables. There are two types of alternative pesticides: one is biological pesticides, such as moth sorghum, century lore, Tao Xiaoling, agricultural land, etc.; the second is the use of compound pesticides, common compounding is dichlorvos + BT, dichlorvos + kung fu Wait. Should pay attention to the use: 1 in the low-age spraying of pests, the effect is good; 2 rotation use of various insecticides, more use of biological pesticides, in order to avoid pests to produce resistance; 3 now pesticides have more contact, you should choose pests for food The best effect of spraying is that the bean pods crawl out of the pods for food at 6:00~8:00 in the morning, and the spraying effect is best. 2. For the yellow scoop jumper, Huang Shougua and other migratory pests. Alternative pesticides include dichlorvos, agricultural land, and phoxim. In use, it should be noted that: 1 large area at the same time the prevention effect is good; 2 when the number of yellow scoops is large, in addition to spray prevention, root larvae should be killed by root irrigation; 3 interval 5~7 days, continuous prevention 2~3 times . 3. Aphids, whitefly, pests. It is easier to kill, and it can be controlled in time with the use of cockroaches, dichlorvos and other agents.

Omethoate
