How to choose pesticides for green fruit production
(Agricultural Wealth Network) In the production of green fruit, the use of pesticides is crucial. Representative varieties of the highly effective biological pesticide abamectin include Abadin, Qimansu, Aifuding, Aweichongqing, 7051 Shamanasu, and others. These pesticides have special efficacy against pests such as red spiders, pear psyllids, and scale insects, while causing no pollution and leaving no residue. 1% Haizheng Miechongling and 1.8% Haijimie are both biological pesticides that are highly effective, low in toxicity, safe, and not prone to inducing pest resistance, and they have remarkable effects against mites, pear psyllids, golden-vein leafminers, and other pests.
Bt insecticide has a special effect on controlling early defoliation disease; representative varieties include Pingfu Sukeling, Kangjunling, Guofukang, Leiai Guoshu Kang, Lubao Dan, 9281 High-Efficiency Rot Clean, and others. Fruit tree rot disease and dry rot disease are the main diseases of apple trees. In the past, asomate was used for control, but it left large residues and also harmed the tree body. Rot-clearing agents with no residue, such as Fubiqing, 9281, and Junduqing, can be used instead for control. For fruit tree ring rot and anthracnose, choosing Daconil M-45, Xiansheng, thiophanate-methyl, carbendazim, and others also gives very good results.
In the past, organophosphorus and pyrethroid insecticides were used extensively to control Lepidoptera insects, but they had a strong killing effect on natural enemies and increased the resistance of pests. It is advisable to switch to new products such as Mieyou Niao No. 3, Shaling Niao, and Tianli No. 2, which are pollution-free insect biological regulators.
The peach fruit borer is a major pest damaging the fruits of apples, pears, jujubes, and others. In the past, 1605 was used for control, but it is highly toxic, leaves many residues, and easily causes poisoning in humans and livestock. The new pesticide products Taoxiaoling, Taoxiao Yicijing, and Guochong Yibianjing all have good control effects.
For aphid control, omethoate has been commonly used for many years, but aphids have developed resistance to it. At present, China has also produced low-toxicity pesticides with imidacloprid as the main ingredient, such as Yashijing, Yibianjing, and Pushiya, and their effects are also very good.
