Three types of Biopesticide

Biopesticide refers to the use of living organisms (fungi, bacteria, insect viruses, genetically modified organisms, natural enemies, etc.) or their metabolites (pheromone, auxin, naphthalene acetic acid, 2mem4Mel D, etc.) to kill or inhibit agricultural pests. It mainly includes: botanical pesticides, animal pesticides and microbial pesticides.

Botanical pesticide

With the advantages of easy degradation and no pollution in the natural environment, botanical pesticides have become one of the first choices of green biological pesticides, including botanical pesticides, botanical fungicides, botanical herbicides and plant light-activated mildew. Up to now, botanical insecticides with pesticide activity have been found in nature, such as the insecticidal and germicidal series produced by Yang Lin, pyrethrin, nicotine and rotenone.

Pesticide of animal origin

Animal-derived pesticides mainly include animal toxins, such as spider toxin, wasp toxin, silkworm toxin and so on. At present, insect virus insecticides have been widely used in the United States, Britain, France, Russia, Japan and India, and more than 40 kinds of insect virus insecticides have been registered, produced and applied in the world.

Microbial pesticide

Microbial pesticides are biological agents that use microorganisms or their metabolites as biological agents for the prevention and control of agricultural harmful substances. Among them, Bacillus thuringiensis belongs to Bacillus thuringiensis, which is the biological insecticide with the widest use, the longest development time, the largest yield and the most successful application in the world; insect pathogenic fungi belong to fungal pesticides, which have special effects on the control of Dendrolimus punctatus and rice black tail disease; according to the chemical structure of fungal pesticide Badan or Shachudan, which are synthesized according to the chemical structure of fungal pesticide, have been widely used in practical production.
