How to choose pesticides in the production of Green fruits

(Agricultural Wealth Network) The use of pesticides is crucial to the production of green fruits. The representative varieties of highly effective biological pesticides abamectin include abatin, azithromycin, alfodin, abamectin, 7051 acaricide, etc. This kind of pesticide has special effect on controlling red spider, pear psyllid, scale insect and other pests, and has no pollution and residue. 1% Haizhengmiongling and 1.8% Huizhime are biological pesticides with high efficiency, low toxicity, safety and difficulty in producing drug resistance. They have miraculous effects on mites, pear psyllid, golden stripe moth and other pests.

Bt insecticides have special effects on early leaf blight control, such as Pingfusukeling, Kangjunling, Guofukang, Leiqi Guoshuokang, Lubaodan and 9281 Gaoyuechuojing. Fruit rot and dry rot are the main diseases of apple trees. In the past, arsenic thiram was used to control them, but the residue was large and harmful to trees. It can be controlled by using non-residue pesticides such as Hubiqing, 9281 and Junduqing. The effect of Dasheng M-45, Xiansheng, Thiophanate-methyl and Carbendazim on fruit ring disease and anthracnose is also very good.

Organophosphorus and pyrethroid insecticides were widely used to control lepidoptera insects in the past, but they had strong lethality to natural enemies and enhanced the resistance of pests. New products such as chlorfenuron No. 3, diflubenzuron and Tianli No. 2 should be used instead.

Peach fruit borer is the main pest of apple, pear and jujube. In the past, 1605 was used for prevention and treatment, but it was highly toxic, with many residues, and was easy to poison humans and animals. The new pesticides Tao Xiao Ling, Tao Xiao Yi Jing and Guo Chong Yi Jing have good control effect.

Omethoate has been commonly used as aphid insecticide for many years, but aphids have developed resistance to it. At present, our country also produces aphid net, once net, aphid and other low-toxicity pesticides with imidacloprid as the main component, the effect is also very good.
