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.

1. Compounding with Bacillus thuringiensis
The compound products on the market include tea core·Bt, sweet core·Bt, alfalfa core·Bt, cotton core·Bt, cabbage·Bt, Bt·pine and other compound products, mainly the compound products registered by Wuda Unioasis(from us)
2. Combination (or alternate use regimen) with low toxicity or commonly used chemical drugs
The compound products on the market also include high chlorine · slanting night nuclear suspending agent, phoxim · cotton nuclear suspending agent, fluoride carbamide · slanting night nuclear suspending agent.

The development trend of insect virus insecticide products shows that the active ingredients of single doses are declining, the development of compound preparations is accelerating, and the market demand is strong, and nuclear polyhedrosis is the dominant factor, especially the nuclear polyhedrosis virus of Spodoptera californica and The research and application of Spodoptera litura nuclear polyhedrosis virus complexed with other varieties are concentrated.

Mixing insect viruses with chemical pesticides below the lethal dose can also effectively enhance the insecticidal rate. This may be because chemical pesticides at lethal doses cannot kill pests, but can greatly reduce the immunity of pests and increase infection. The probability of virus, thus showing a synergistic effect.
The compounding of insect viruses and commonly used high-efficiency and low-toxic chemical drugs is mainly to solve the problems of quick-acting and long-lasting effects, effectively reduce the dosage of chemical pesticides, and gradually solve the problem of pesticide residues.

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.
