Differentiating the type of biological pesticide
Biopesticidal active ingredients are naturally occurring substances and are widely viewed as having unique advantages. Biological pesticides are mainly divided into three major types of plant sources, animal sources and microbial sources.
Plant-sourced pesticides have the advantage of being easily degradable and pollution-free in the natural environment, and have now become one of the first choices for green biological pesticides. They mainly include plant-derived pesticides, plant-derived fungicides, plant-derived herbicides, and plant photo-activated moldy poisons. . At present, the botanical insecticides that have been discovered by nature in the field of pesticide activity include the Boluohui insecticidal series, pyrethrins, nicotine, and rotenone produced by Yanglin.
Animal-derived pesticides mainly include animal toxins such as spider toxins, wasp toxins, and nereis. At present, insect virus insecticides have been widely used in the United States, Britain, France, Russia, Japan, and India, and there are more than 40 kinds of insect virus insecticides registered, produced and applied in the world.
Microbial source pesticides use microorganisms or their metabolites as biological agents for controlling agricultural harmful substances. Among them, Bacillus thuringiensis belongs to the genus Bacillus, and it is the world's most widely used, longest-developed, highest-yield, and most-applied biopesticide. Insect-pathogenic fungi are fungal pesticides against pine caterpillars and rice black tails. Leaf disease has special effects; According to the chemical structure of the fungal pesticide cocloperin, the synthetic insecticides such as Bataan or Shandandan are widely used in actual production.
