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.

Insect virus insecticides with its strong specificity, the use of "poison to fight poison" new insecticidal concept, unique mechanism of action, good prevention and control effect, and has a significant advantage is the quality of agricultural products, agricultural ecological environment is very safe, is the future national focus of development.

Bacillus thuringiensis (B.t) was mixed with nuclear polyhedrosis virus. Compared with insect virus, B.t had low cost and quick efficacy. After mixed with insect virus, the sterilizing effect was significantly improved. Wuda oasis registered tea nucleus · Bt suspension agent, cotton nucleus · Bt suspension agent, polysavone · Bt suspension agent are this kind.

Main advantages of insect virus insecticides:

• Strong pertinence, only effective to target pests, does not harm natural enemies and other non-target organisms, is conducive to maintaining ecological balance and preventing pests from rampant again.
• Pests do not easily develop resistance. Insect viruses are essentially microorganisms with nucleic acid structures that can co-evolve with pests, which have difficulty developing resistance. So compared with chemical pesticides, insect virus insecticides have more market potential in pest resistance management.
• No residue. The main components of insect virus insecticides are natural organisms, and there is no safety interval for the products, which can be harvested on the same day. For organic and green agricultural production bases with requirements of agricultural residues, insect virus insecticides are completely safe to use green pest prevention and control products.

• 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

• Eco-friendly, safe to crops, harmless to human beings and animals.
• The anti-effect to spodoptera litura and pod borer are particularly significant.
• The effect after application is very fast. After 4 hours, insects will be poisoned and stop feeding, thus can do no harm to crops.
• 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.

Dosage:

• WP: 750-1125g/Ha, spray

The main advantage of insect virus pesticides:

• Strong targeted, only effective for target pests, non -target creatures such as natural enemies, which are conducive to maintaining ecological balance and preventing pests from rampant.
• Pests are not easy to produce resistance. Insect virus is essentially a microorganism with nucleic acid structure that can be evolved with pests, which is difficult to produce resistance. Therefore, compared to chemical pesticides, insect virus pesticides have more market potential in the treatment of pest resistance.
• Safe without residual. The main component of insect virus pesticides is natural organisms, and the product is not safe to collect on the same day. For the organic and green agricultural product production bases required by agricultural residues, insect virus pesticides are completely safe and can be used with confidence. Pests green prevention and control products.
