Under the current production conditions, it is necessary to rationally select pesticides, scientific and safe drugs, and firstly promote the use of biological pesticides .
High-efficiency bio-pesticide avermectin is an antibiotic produced by fermentation and purification process. It has the functions of killing insects, killing mites and killing nematodes. It has special effects for controlling pests such as red spider, pear hibiscus and scale insects, and is safe for humans and animals and natural enemies. At the same time, there is no pollution and no residue. Representative varieties are Abadin, Qiqisu, Aifuding, Aweidiqing, and 7051 acaricide. The common feature of these agents is that it is mainly based on stomach poisoning, and it can also be used for lateral transmission. By interfering with the nerve information transmission process of pests, pests can paralyze, refuse to eat and die within a few hours.
The use of avermectin is not easy to produce resistance, and it is also effective against pests that are resistant to other pesticides. 1% Haizheng worms, 1.8% gibberin, 1.8% violent, for pests such as mites, pear hibiscus, golden moths, etc., are also several high-efficiency, low-toxic, safe, and resistant to chemicals. Biological pesticides.
Bt insecticides have special effects in preventing early defoliation. Bt preparations are low cost, efficient, safe and do not pollute the environment. The production of high-quality fruit with no pollution and low residue, the use of quick-acting fungicide is the best choice. It is a fast-acting fungicide with systemic properties and is a new product with excellent pollution-free pesticides. Representative varieties include Pinghuo Keling, Kangzhuling, Guofukang, Reqiguoshukang, Lvbaodan, and 9281 high-efficiency rot.
Fruit tree rot disease and dry rot are the main diseases of apple trees. In the past, Fumei arsenic was used for prevention and control, and the residue was large, which also harmed the tree body. It can be changed to use no residue medicine such as rotification, 9281, and bactericidal clearing.
Fruit tree ring disease, anthrax disease using Dasheng M-45, Xiansheng, methyl thiophanate, carbendazim and other effects are also very good. In the past, lepidopteran insects were used in large quantities to use organophosphate and pyrethroid insecticides, but they have strong killing power against natural enemies and enhance the resistance of pests. It is better to use chlorpyrifos No. 3, chlorpyrifos and days. Non-polluting insect biological regulators such as No. 2. Diflubenzuron is a non-toxic pesticide, but it has special effects in controlling lepidopteran pests. Not only is it highly active against larvae and eggs, but it also produces infertility in adults.
Peach worms are the main pests that damage apples, pears, dates and other fruits. In the past, the use of 1605 control, toxicity, residue, and human and animal poisoning. In recent years, the use of Tao Xiaoling and low toxicity, high efficiency peach small net and fruit insects have a good effect. Acaricides have been commonly used for many years in omethoate, but have developed resistance. Even if the concentration is increased, the control effect is still not good. In recent years, the popularization of imidacloprid, which was successfully developed by Bayer in Germany, has effectively reduced the number of medications. At present, China has also produced pesticides with imidacloprid as the main component, such as phlegm, once clean, and phlegm, and the effect is also very good.
