Imidacloprid is a nicotine type super-effective insecticide, has a broad spectrum, high efficiency, low toxicity, low residue, pest resistance is not easy to produce, and it is safe to humans, animals, plants and natural enemies. It also has contact, stomach and systemic absorption. And other multiple effects. After the insects contacted the agent, the normal conduction of the central nervous system was blocked, causing paralysis to die. The product has good quick effect, and has a high control effect one day after the drug, and the residual period lasts for about 25 days. The efficacy is positively correlated with temperature, with high temperature and good insecticidal effect. Mainly used to prevent sucking mouthpart pests.
It is mainly used to prevent sucking mouthpart pests, such as aphids, migratory locusts, whiteflies, leafhoppers, and thrips; some pests of the order Coleoptera, Diptera, and Lepidoptera, such as rice weevil and rice turf , rice borers, leaf miners, etc. are also effective. However, it is not effective against nematodes and red spiders. Can be used for rice, wheat, corn, cotton, potatoes, vegetables, sugar beets, fruit trees and other crops. Due to its excellent systemic properties, it is particularly suitable for application by means of seed treatment and granule spray. In general, the effective ingredient is 3~10 grams per mu, sprayed or seeded with water. Safety interval 20 days. Pay attention to protection when spraying, prevent contact with the skin and inhalation of powder, liquid medicine, and wash the exposed parts with water after use.
Do not mix with alkaline pesticides.
Do not spray in strong sunlight, so as not to reduce the efficacy.
The control of spirolacanthes, apple tumor nevus, peach aphid, pear hibiscus, leaf roller moth, whitefly, spotted fly and other pests, can be sprayed with 10% imidacloprid 4000 ~ 6000 times, or 5% imidacloprid EC 2000 ~ 3000 times spray . Prevention of warts: You can choose Shennong 2.
Continuous use in recent years has resulted in high resistance, which has been banned in countries with rice.
Abamectin is a pesticidal and acaricidal agent for agricultural veterinary use and a macrolide disaccharide compound. Abamectin has contact and stomach poisoning effects on insects and acarines and has a weak fumigation effect, causing a slower lethal effect. However, there is less residue on the plant surface.
Contact, stomach poison, strong penetration. It is a macrolide disaccharide compound. It is a natural product isolated from soil microorganisms. It has contact and stomach poisoning effects on insects and mites with weak fumigation and no systemic uptake. But it has a strong penetration of the leaves, can kill the pests under the epidermis, and long residual period. It does not kill eggs. Its mechanism of action differs from that of general insecticides in that it interferes with neurophysiological activities and stimulates the release of r-aminobutyric acid, while r-aminobutyric acid has an inhibitory effect on arthropods' nerve conduction, and fleas, gnats, and insects Symptoms of numbness occur when the larvae come into contact with the drug, and do not feed without activity. They die after 2-4 days. Because it does not cause rapid dehydration of insects, it has a slower lethal effect. Although it has a direct killing effect on predatory and parasitic natural enemies, it has little damage to beneficial insects due to its low surface residue. The effect on root-knot nematodes is obvious.
