Biological pesticide concept:
Bio-pesticide refers to a kind of pesticide preparation that uses biological organisms or their metabolites to control pests, germs, weeds, nematodes, rodents and other harmful organisms, or a pesticide preparation with specific effects through biomimetic synthesis.
How to classify biological pesticides :
According to the source of the drug, the biological pesticide can be classified into a microbial biopesticide, a plant biopesticide, and an animal biopesticide.
It can also be divided into two main categories: biochemical pesticides (biochemical pesticides such as hormones and growth regulators) and microbial pesticides (such as bacterial and fungal preparations).
According to its composition and source, Chinese bio-pesticide can be divided into four parts: microbial live pesticide, microbial metabolite pesticide, plant-derived pesticide and animal-derived pesticide. According to the control object, it can be divided into insecticides , fungicides, herbicides, acaricides, rodenticides, plant growth regulators, and the like. For the purposes of its use, biological pesticides are generally divided into two categories: direct use of biological organisms and utilization of physiologically active substances derived from organisms. The former includes bacteria, fungi, nematodes, viruses and antagonistic microorganisms, and the latter includes agricultural antibiotics and plants. Growth regulators, sex pheromones, feeding inhibitors, juvenile hormones, and physiologically active substances derived from plants. However, in the practical application of agricultural production in China, biological pesticides generally refer to microbial pesticides that can be used for large-scale industrial production.
