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, and infects the whole body of the pest, and finally causes the death of the pest. Diseases and feces and dead insects can then spread the virus to other pests' so that the virus can spread in the pest population, thereby controlling the pests. Does not pollute the environment.

After insects feed the pesticide, Bacillus thuringiensis first role in insect midgut cells, reducing the insect's immune system, making it easier for insects to get infected with the PrGV. The PrGV then enters the body and carry bulk copy and reproduction, and soon spread rapidly to each part of pests body. The pests will lose the ability to harm crop. Eventually, the body will change into water and lead to death. The PrGV keep on infecting the healthy pests and next generation through the body fluids and feces of the dead insects, just like a worm plague, in this way, it will control pest in a long time.

• Obtain organic certification and without pesticide residue
• Pests has no resistance for virus, long time effective
• Continuous use three to four times can effectively control the initial population number of cabbage worm, diamondback moth

1. Slightly toxic: with pure biological materials of agricultural production pure natural ingredients, biopesticide is harmless to crops, which ensure the safety of food form the source.
2. Efficient and long-lasting: virus spread in the insect populations, after infected, it will cause domino effect, which will make the aftereffect very remarkable.
3. Non-resistance: Non-resistance,can be long-term used. It is the best choice in dealing with high resistant insects.
4. Eco-friendly: Target only on the host rang. our virus biopesticide can kill pests without affecting the natural enemies and protect the natural eco-system.
5. Environmental compatibility: Low pollution, low power consumption, low carbon emissions in the process of production, no residual and environment friendly.
6. Cost-effective: Long-term effective decrease the frequency of applying pesticides and reduce the cost of both pesticides and labor.
