Biological pesticides are pure biological fungi without any chemical elements and have irreplaceable practical value in future agricultural production. Its main technical routines have the following four aspects:
1. The use of biological pesticides should first understand the biological characteristics. The so-called biological characteristics refer to the scope of application of the agent, the action route, the effect component and the mechanism of action, etc., such as sulphate, fungus, enemy, etc., their active ingredients are Bacillus thuringiensis, the application range is on the lepidopter The larvae of the larvae are toxic and ineffective, and are ineffective against mites, mites, and mites; the path of action is stomach poisoning; the mechanism of action is that the worms after death can also infect other similar pests that have not been exposed to pesticides.
2. Mixing of biological agents 1 Mixing of biological insecticides: Biocides are turbid and mixed with most chemical insecticides, because most chemical pesticides are chemically acidic and physiologically neutral, and there are no bacteria or fungi. The inhibitory effect and the neutralization reaction can be sufficiently mixed. It can be seen that the biological insecticide can not be mixed with the chemical fungicide. Once compounded, the active bacterial spore of the biological agent will be killed and lose its proper effect. 2 Mixing of biological fungicides: Biological fungicides can be mixed with most chemical agents and biological agents, but they cannot be mixed with alkaline drugs. Only a few kinds of drugs cannot be mixed with acidic agents. For example, Trichoderma can be used with most Biocides and chemical pesticides are mixed at the same time.
3. Main characteristics of biological agents The common characteristics of biological agents are characterized by low toxicity, no residue, slow action and long duration. The ratio of concentration and dosage are lower than the exact bottom of the chemical. When the dosage is slightly larger, it will not cause phytotoxicity to plants, and it is safer for humans and animals, and does not pollute the environment.
4. Conditions and matters for the use of biological drugs The use of biological pesticides is recommended to use two or more drugs. In the case of prophylaxis and continuous use, one drug can be used alone, but it should not be used alone during the high incidence of pests and diseases. Before application, the applicator should be cleaned before being prepared and used. When applying the drug, it should be avoided as much as possible to avoid the effect of high light and high temperature.
