Sweet Corn Borer Killing Biological Insecticides On Fruit PrGV

Corn Borer Killing Pesticide Biological Pesticide Killing Leaf Folder on Fruit Corns PrGV

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 · Su suspension agent are this kind.

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.

Compared with other pesticides, viral pesticides have the following advantages:
1. Specificity: The infection mechanism of insect viruses requires the spike protein on the surface of the virus to recognize and bind to the receptor glycoprotein on the surface of the host cell, in order to infect the host and only kill the target host.
2. Safety: Viral pesticide is harmless to humans and animals, does not kill natural enemies and other beneficial insects, does not pollute the environment, and NPV is of great significance for the protection of the ecological chain.
3. No residue: Virus is a kind of protein, which has no residue on crops.
4. Epidemic: The virus can spread horizontally and vertically in the pest population and is contagious.
5. The production process is pollution-free and low energy consumption. An insect is a virus synthesis factory.
6. High efficiency and persistence: The nuclear polyhedrosis virus can remain active in the soil for up to 5 years. After the diseased and dead insects rot in the field, a large amount of viruses will be released, and the number of field viruses will continue to be maintained; thus reducing the number of spraying and reducing The cost of medicines and labor, and the overall cost will also decrease.
7. Farmland pest is not easy to develop resistance: The virus has no cell structure, no complete enzyme system, and the factors that play a role in the metabolic pathway of microorganisms are not affected, and it is not easy to develop resistance. So far, there is no relevant report on insect virus resistance. For example, the human body has no resistance to the new coronavirus and SARS virus, nor corresponding immunity, and no targeted drugs.

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.
