Usage
Abamectin is mainly used for the control of various agricultural pests such as fruit trees, vegetables and flowers. Such as small cabbage moth, spotted fly, mites, aphids, thrips, rapeseed, cotton bollworm, pear yellow psyllid, tobacco moth, soybean moth and so on. In addition, abamectin is also commonly used in the treatment of various internal and external parasites in pigs, horses, cattle, sheep, dogs and other animals, such as roundworms, lungworms, horse stomach flies, cow skin flies, pruritus mites, hair lice, blood lice, and various parasitic diseases of fish and shrimp.
Action mechanism
Abamectin kills pests mainly through stomach toxicity and touch action. When pests touch or bite the drug, its active ingredients can enter the body through the insect’s mouth, paw pads, foot sockets and body walls and other organs. This will cause the increase of gamma-aminobutyric acid (GABA) and the opening of glutamate-gated CI- channels, so that the Cl- inflow increases, causing the hyperpolarization of the neuronal rest potential, resulting in the normal action potential can not be released, so that the nerve paralysis, muscle cells gradually lose the ability to contract, and eventually lead to the death of the worm.
Function characteristics
Abamectin is a kind of antibiotic (macrolide disaccharide) insecticide with high efficiency, broad spectrum, contact and stomach toxic effects. When sprayed on the leaf surface of the plant, its effective ingredients can penetrate into the plant body and continue in the plant body for a period of time, so it has long-term performance. At the same time, abamectin also has a weak fumigation effect. The disadvantage is that it is not endogenic and does not kill eggs. After use, it usually reaches its peak effect within 2 to 3 days. Generally, the effective period of lepidoptera pests is 10 to 15 days, and mites are 30 to 40 days. It can kill at least 84 pests such as Acariformes, Coleoptera, hemiptera (formerly homoptera) and Lepidoptera. In addition, the mechanism of action of abamectin is different from that of organophosphorus, carbamate and pyrethroid insecticides, so there is no cross-resistance to these insecticides.

Acarus |
When mites occur, apply medicine, use 1.8% cream 3000~6000 times the liquid (or 3~6mg/kg), evenly spray |
1. When using, you should take personal protection, wear protective clothing and gloves, and avoid inhaling liquid medicine. 2. Abamectin is easily decomposed in alkaline solution, so it cannot be mixed with alkaline pesticides and other substances. 3. Abamectin is highly toxic to bees, silkworms and some fish, so it should be avoided to affect the surrounding bee colonies, and stay away from sericulture, mulberry orchard, aquaculture area and flowering plants. 4. The safe interval of pear trees, citrus, rice is 14 days, cruciferous vegetables and wild vegetables are 7 days, and beans are 3 days, and can be used up to 2 times per season or per year. 5. In order to delay the emergence of resistance, it is recommended to rotate the use of agents with different insecticidal mechanisms. 6. Pregnant and lactating women should avoid contact with this medicine. 7. Used containers should be properly disposed of and not discarded at will. |
