What are the advantages of biological pesticides over traditional pesticides

Compared with chemical pesticides, biological pesticides have many essential differences in the source of effective components, industrial production methods, mechanism of pest control and disease prevention, and mode of action. Biological pesticides are more suitable for expanding the proportion of application in future integrated pest management strategies. In summary, biopesticides have the following advantages.

Strong selectivity, safe for humans and animals

At present, the biological pesticide products developed and successfully applied in a large scale in the market only have effects on diseases and insect pests, and are generally safe to humans, livestock and various beneficial organisms (including animal natural enemies, insect natural enemies, bees, pollinators, fish, shrimp and other aquatic organisms), and have relatively small effects on non-target organisms.

Low impact on ecological environment

Biological pesticides control harmful organisms, mainly by using some special microorganisms or microbial metabolites have insecticidal, disease prevention, growth promotion functions. Its effective active ingredients completely exist and come from the natural ecosystem, its biggest characteristic is easy to be decomposed by sunlight, plants or various soil microorganisms, it is a kind of natural, return to the natural normal material circulation mode. Therefore, they can be considered safe and pollution-free to the natural ecological environment.

Inducing pest disease

Some biological pesticides (entomopathogenic fungi, insect viruses, insect microsporidia, entomopathogenic nematodes, etc.) have the ability of horizontal or vertical transmission in pest populations, and have the ability to colonize, spread and develop epidemics under certain conditions in the field. Not only can it control the pest of the current generation, but also it can inhibit the pest population of the offspring or the next year, and has obvious aftereffect.

Agricultural and sideline products can be used for production and processing

At present, the domestic production and processing of biological pesticides generally mainly use natural renewable resources (such as corn, soybean cake, fish meal, wheat bran or some plant bodies of agricultural and sideline products), the source of raw materials is very wide, and the production cost is relatively low. Therefore, the production of biopesticides generally does not produce raw materials that compete with the production of chemical synthesis products using non-renewable resources (such as oil, coal, natural gas, etc.).
