Biological pesticides are pesticides made from organisms such as bacteria, fungi, and viruses as raw materials. It is characterized by safety and reliability, no pollution to the environment, no pollution to humans and animals, and easy access to raw materials, low production costs, is a pesticide with broad development prospects in the prevention and control of crop pests and diseases. Common biological pesticides in production are the following:
Bt emulsion: It is a commonly used bacterial biopesticide. Its finished product is a beige emulsion with good emulsifying properties and a broad insecticidal spectrum. The control effect of lepidoptera pests on more than 20 kinds of vegetables, tea, Fruit, tobacco and other plants is as follows: 80-90%, the main control objects are pine caterpillars, corn borer, cotton bollworm, armyworm, rice leaf roller, tea caterpillar and so on. Bt emulsion is a stomach poison that can produce a special enzyme after pests eat it. This enzyme can decompose a protein in the insect's intestine, thereby perforating the intestinal tract of the insect. The contents of the intestine flow into the body cavity and eventually die of sepsis. When using, the temperature should be kept above 15°C, generally 20°C, and the application time should be 2-3 days earlier than chemical pesticides.
Bacterial and Acaricidal Bacillus: Cabbage worms eat the leaves that are plagued with the bacterium, and the wall of the intestines will quickly perforate and become mud and die. The acaricidal bacillus is used to control the rice leaf roller and the rice stem borer. It can also control insects such as flies, mosquitoes, armyworms, pine caterpillars, white ants and rice borers.
Beauveria bassiana: It is a fungal bio-pesticides and has special effects on the control of pine caterpillars and rice pests. After being contacted with pests, the Beauveria Bacteria liquid enters the pests through the body wall and germinates mycelium quickly and absorbs the body fluid of pests, causing the insects to become stiff and die.
Jinggangmycin: There are special effects in controlling rice sheath blight. It can inhibit the mycelium of rice sheath blight pathogen, and it is valid for 15-20 days. It is resistant to rain erosion and is non-toxic to humans and animals.
Agricultural antibiotics and plant antibiotics. These two types of pesticides are fungal biopesticides. The antibiotics used in production include kasugamycin, chloramphenicol, polyoxin, oxytetracycline, griseofulvin, and actinomycin-streptomycin. Such as agricultural anti-120 is a new type of agricultural antibiotics, for melon, fruit, vegetables, flowers, wheat, tobacco powdery mildew and rice, wheat sheath blight, has a good control effect.
