Pure biological preparation HaNPV insecticide kill cotton bollworm Helicoverpa armigera

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.

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.

• 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.
