Natural Organic Insect Viral Pesticide PrGV &Bt WP for Vegetable Pieris Rapae Granulosis Virus NPV Biopesticide

Pierisrapae granulosis is only used to control cabbage caterpillars, mainly in cruciferous vegetables.

Cabbage caterpillar granulosa virus is a microbial source of low toxicity obligate insecticidal thorn, PrGV is a pollution-free biological pesticide, mainly for stomach poisoning.

Pests infect the virus through feeding, and then the virus reproduces in the pest and infects the entire body of the pest, eventually causing the pest to die.

Insect feces and dead insects then transmit the virus to other pests, making the virus popular in the pest population, thereby controlling the damage of the pests. Do not pollute the environment.

PrGV.Bt Biological Virus Pesticide: The active ingredient of PrGV.

Bt biological pesticide is PrGV (pieris rapae granulosis viru) 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, there by controlling the pests. Does not pollute the environment.

4. The aftereffect is very significant. The PrGV can be horizontal or vertical transmission through eggs in pest populations, so the efficacy can sustain a long time, up to 10 days. It can control the pest population density of the next generation. Appling one time can benefit long term, which reduces the cost of medication in a large degree.
