Comprehensive introduction of microbial pesticides
Microbial pesticides widely promote the use of the government, it is a kind of rapid development of biological pesticides. Microbial pesticides are a class of pesticides made from microorganisms such as bacteria, fungi, and viruses. Microbial pesticides include agricultural antibiotics and living microbial pesticides. The characteristics of microbial pesticides are safe and reliable, do not pollute the environment, do not cause pollution to humans and animals, and are easy to obtain raw materials, and have low production costs. They are a kind of pesticide with broad development prospects in the prevention and control of crop diseases and insect pests.
Biological pesticides also have advantages and disadvantages:
The advantages of bio-pesticides that most biological pesticides is low or slightly toxic and difficult for users to produce poison; conducive to the quality and safety of agricultural products, pollution, does not destroy the ecological balance; not easy to produce drug resistance. The shortcomings of biological pesticides are: generally only work on one pest, and have no effect on other pests; high temperature and humidity requirements, suitable temperature for microbial pesticide use is 15-30 ° C; sensitive to ultraviolet light, ultraviolet light to microbial source Pesticides have a lethal killing effect; they are slow in efficacy, and the pests and diseases will not be effective immediately after administration. The application time should be 2-3 days earlier than chemical pesticides.
The biological pesticides commonly found in production are as follows: Bt emulsion, green worm and bacillus, Beauveria bassiana, Jinggangmycin, agricultural antibiotics and plant antibiotics.
The Galvanized Welded Wire Mesh is made of high-quality low-carbon iron wire or steel wire and is formed by automated precision mechanical equipment spot welding. The surface treatment of the entire mesh galvanized process is used to make the mesh surface smooth and tidy; the structure is firm and uniform; and the overall performance is good.
