What are biogenic pesticides?

Biological pesticides refer to pesticides developed using biological resources, referred to as biological pesticides. Biology includes animals, plants and microorganisms. Therefore, biological pesticides are divided into three categories: animal pesticides, botanical pesticides and microbial pesticides. It can be said that it includes all types of creatures on earth. Nowadays, some genetically modified crops with pesticide effects or resistance to pesticides are also classified as biological pesticides.

Biological pesticides include biochemical pesticides, microbial pesticides, botanical pesticides, genetically modified organisms and natural enemy organisms. Their definitions are:

(1) Biochemical pesticides must meet the following two conditions: ① It is not directly toxic to the object of control, but only has special effects such as regulating growth, interfering with mating or attracting; ② It must be a natural compound, and if it is artificially synthesized, its structure must be consistent with Natural compounds are the same (differences in the ratio of isomers are allowed). Including pheromones, hormones, natural plant growth regulators and natural insect growth regulators and enzymes.

(2) Microbial pesticides include pesticides that use living organisms such as bacteria, fungi, viruses, protozoa or genetically modified microorganisms as active ingredients, and have the effect of preventing and controlling diseases, insects, grass, rats and other harmful organisms.

(3) Pesticides in which the active ingredients of plant-derived pesticides are derived from plants.

(4) Genetically modified organisms are agricultural organisms that can prevent and control diseases, pests, grasses and other harmful organisms that endanger agriculture and forestry, and use exogenous genetic engineering technology to change the composition of the genome.
