Biological pesticides can be roughly divided into seven categories:
First, botanical pesticides, the main raw materials are directly derived from plants, such as matrine and azadirachtin.
The second is microbial pesticides. The main raw materials are live bacteria, fungi, and viruses, such as Beauveria bassiana and Spodoptera exigua nuclear polyhedrosis virus.
The third type is mineral pesticides. The main raw materials are minerals, such as mineral oil and sulfur.
The fourth type is natural enemy biopesticides, which are mainly used for artificially bred animals that can control pests and diseases, such as pine caterpillars, red-eyed bees, and flat-bellied bees.
The fifth is biochemical pesticides. The main raw materials already exist in organisms, and they have no direct toxicity to pests and diseases. They play a role in regulating the growth and development of crops or pests and diseases, such as brassinolides, gibberellic acid, and attracting insects.
Sixth, protein or oligosaccharide pesticides can induce plants to develop resistance to diseases after use, such as amino oligosaccharides, chitosan, lentinan, etc.
Seventh is agricultural pesticides, the main raw materials are produced by microbial fermentation, such as kasugamycin, ningnanmycin, and abamectin.
