The active ingredient of PrGV.Bt biological pesticide is PrGV (pieris rapae granulosis virus) and Bt (Bacillus thuringiensis). PrGV is a low-toxic, obligate insecticidal thorn of microbial origin. It is a non-pollution biological pesticide, mainly for gastric toxicity.
The pests infect the virus by feeding, and then the virus propagates in the pest body, spreading throughout the pest's system and ultimately causing death. Diseases and feces from dead insects can then spread the virus to other pests, allowing the virus to propagate through the pest population and effectively control infestations. This method does not pollute the environment.
After insects ingest the pesticide, Bacillus thuringiensis first acts on insect midgut cells, reducing the insect's immune system and making it more susceptible to PrGV infection. The PrGV then enters the body, replicates rapidly, and spreads throughout the pest's system. The pests lose their ability to harm crops and eventually die as their bodies liquefy. The PrGV continues to infect healthy pests and subsequent generations through body fluids and feces of dead insects, creating a sustained pest control effect.

Main Advantages of Insect Virus Pesticide
Strong targeting: Only effective for target pests, non-target creatures such as natural enemies remain unaffected, which helps maintain ecological balance and prevent pest outbreaks.
Resistance prevention: Insect virus is essentially a microorganism with nucleic acid structure that can evolve with pests, making resistance difficult to develop. Compared to chemical pesticides, insect virus pesticides have more market potential in treating pest resistance.
Safe without residue: The main component is natural organisms, and the product is safe to harvest on the same day. For organic and green agricultural production requiring no residues, insect virus pesticides are completely safe.
Why Bio Pesticide in Vegetables is Very Necessary
When we eat vegetables, in many situations they don't require further processing (like salads, sushi, etc.). Therefore, product quality and safety requirements should be more strict. Chemical pesticides have strong toxicity - even after washing, residues remain in vegetables and fruits. Long-term consumption of produce containing chemical pesticides affects human health.
Biopesticide contains no chemical additives, is all-natural, harmless to crops, and ensures food safety from the source. With the concept of green and non-pollution deeply rooted in our minds, bio-pesticide has become the best choice for implementing green control in modern agriculture.
