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.
Working Mechanism
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.
Features:
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
Highlights
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.
Precautions:
When using this product, wear protective clothing and gloves, masks to avoid inhalation of liquid medicine, do not eat or drink while drinking. After application, wash hands and face, and clean the skin of exposed parts in a timely manner, be sensitive to silkworms, and avoid use around silkworm and mulberry areas.
