HaNPV WP Pure Organic Armigera Cotton Insecticides For Vegetable Crops

Cotton Crop Pesticides HaNPV WP Pure Organic Pest Virus Helicoverpa armigera NPV Insecticide for Cotton Tobacco Chili​

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.

Working Mechanism:
Helicoverpa armigera nucleo polyhedro virus (HaNPV) is a microorganism that kills cotton helicoverpa armigera. After spraying onto crops and being eaten by pests, the virus particles replicate and multiply in the pest body, and quickly spread to all parts of the pest. Parts of the body are drastically engulfed to consume the tissues of the worms, and the pests do not eat or move during the period of ‘illness’, causing a sub-lethal effect, and eventually the whole body is killed by water, spraying on the insects, the larvae that will hatch will bite after eating the egg shell Death by feeding on the virus. In addition, virus particles can continue to be transmitted to the next generation or other pests through the body fluids and feces of dead insects like a ‘plague’, so that field pests can be effectively controlled for a long time.

Main advantages of insect virus insecticides:
1. 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.
2. 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.
3. 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.

1. Can be used for aircraft spraying, suitable for large area control of helicoverpa armigera.

2. Excellent effect to the oriental tobacco budworm on tobacco and chilli.

3. No safety interval period.

4. Pure biological preparation, harmless to fish, shrimp, humans and animals.

5. Strong selectivity, no damage to natural enemies, special effect on helicoverpa armigera.

6. Outstanding resistance to drug resistance and stubborn pests, no drug resistance after application.

7. Significant aftereffect. The virus can spread among generations of pests, and the drug effect lasts a long time.

Dosage: 3200~6400mL/Ha, spray
