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.

The first is the combination of different insect viruses, including two or more than two different kinds of insect viruses, the purpose is to broaden the insecticidal spectrum of the product through the combination, so that the insect virus products are accepted by more markets.
In the process of virus recombination, not only the insecticidal spectrum was enlarged, but also some viruses were found to have synergistic effect on other viruses, which increased the mortality of pests and had better insecticidal effect.

On the other hand, in order to improve the control effect of insect virus on larval larvae, the use of insect virus and some chemical pesticides is also being studied, and a great breakthrough has been made in this aspect.
The strategy for this approach is to mix insect virus products with certain chemical pesticide products in "packages" for use in the field.
It is found that some chemical pesticides have obvious synergistic effect on insect virus, which can accelerate the rate of disease and death of insect pests after infection with virus, and increase the degree of acceptance of control effect by users.
In fact, for chemical pesticides, especially some strong chemical pesticide products, patentability adopted strategies of "used with insect virus are synergies, not only can reduce the use of chemical pesticides in itself, but also can significantly reduce the pests of the chemical pesticide resistance, prolong the life of the market, at the same time can greatly reduce the pesticide residue.

1. Obtain organic certification and without pesticide residue

2. Pests has no resistance for virus, long time effective

3. Continuous use three to four times can effectively control the initial population number of cabbage worm, diamondback moth

1. Eco-friendly, safe to crops, harmless to human beings and animals.

2. The anti-effect to spodoptera litura and pod borer are particularly significant.

3. The effect after application is very fast. After 4 hours, insects will be poisoned and stop feeding, thus can do no harm to crops.

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.
