What are the differences between Imidacloprid and Abamectin?
Imidacloprid and Abamectin are two major insecticide varieties
Imidacloprid is a nicotine super-efficient insecticide with broad spectrum, high efficiency, low toxicity, low residue, pests are not easy to produce resistance, safe for humans, animals, plants and natural enemies, and has contact, stomach, and systemic absorption. Wait for multiple effects. After the pests are exposed to the agent, the normal conduction of the central nervous system is blocked, causing paralysis to die. The product has a good quick-acting effect and has a high control effect 1 day after the medicine, and the residual period is as long as about 25 days. The drug effect and temperature are positively correlated, the temperature is high, and the insecticidal effect is good. Mainly used to control sucking mouthparts pests.
It is mainly used to control sucking mouthparts pests such as aphids, planthoppers, whiteflies, leafhoppers, and thrips; certain pests of Coleoptera, Diptera, and Lepidoptera, such as rice weevil and rice negative mudworm Rice locusts, leaf miners, etc. are also effective. But not effective against nematodes and red spiders. Can be used in rice, wheat, corn, cotton, potatoes, vegetables, beets, fruit trees, and other crops. Due to its excellent systemic properties, it is particularly suitable for application by seed treatment and granulation. Generally, the active ingredient is 3~10 grams, sprayed with water or seeded. The safety interval is 20 days. Pay attention to the protection when applying for the medicine, prevent contact with the skin and inhaled powder, liquid medicine, and wash the exposed parts with water in time.
Do not mix with alkaline pesticides.
It is not advisable to spray under strong sunlight to avoid reducing the efficacy.
Control pests such as Spiraea japonica, apple mites, peach aphid, pear hibiscus, leaf roller moth, whitefly, and leaf larvae, spray with 10% Imidacloprid 4000-6000 times liquid, or 5% Imidacloprid emulsifiable oil 2000-3000 times. Prevention and control: You can choose Shennong 2.1% cockroach gel bait
The continuous use in recent years has caused high resistance and has been banned in countries on rice.
Abamectin is an insecticide, acaricide, and macrolide disaccharide for agricultural veterinary use. Abamectin has a contact and stomach toxic effect on insects and mites and has a weak fumigating effect, and the lethal effect is slower. However, there is less residue on the surface of the plant.
Contact, stomach poison, strong penetration. It is a macrolide disaccharide compound. It is a natural product isolated from soil microorganisms. It has a contact and stomach toxicity effect on insects and acarids, and has a weak fumigation effect, and has no systemic action. However, it has a strong osmotic effect on the leaves, which can kill the pests under the epidermis and has a long residual effect. 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 inhibits the nerve conduction of arthropods, such as mites, mites, and insects. The larvae appear paralyzed after contact with the agent, inactive and do not feed, and die after 2-4 days. It does not cause rapid dehydration of insects, so its lethal effect is slower. Although it has a direct killing effect on predatory and parasitic natural enemies, it has less damage to beneficial insects due to the less residual surface of plants. It has obvious effects on root-knot nematodes.
