emamectin benzoate (137512-74-4) mechanism of action
The insecticide emamectin benzoate mainly acts on the nervous system of insects. When dead pests come into contact with or eat the leaves sprayed with the pesticide, it will cause paralysis of the pests, weaken the activity of the pests, and prevent normal metabolism. Stop feeding, and within 3 to 4 days, a large number of pests will die.
The pesticide emamectin benzoate can enhance the effects of neurotic substances such as glutamate and γ-aminobutyric acid (GABA), causing a large amount of chloride ions to enter nerve cells, causing loss of cell function and disrupting nerve conduction. Stop eating immediately after exposure, and irreversible paralysis will occur, reaching the highest fatality rate within 3-4 days. Because it is closely combined with the soil, does not leach, and does not accumulate in the environment, it can be transferred through Translaminar movement, and is easily absorbed by crops and penetrates into the epidermis, so that the applied crops have long-term residual effects, and the second crop appears after more than 10 days. It has a peak insecticidal mortality rate and is rarely affected by environmental factors such as wind and rain.
emamectin benzoate (137512-74-4) action

It has a very good effect at a very low dose (0.084~2g/ha), and does not harm beneficial insects in the process of pest control, which is conducive to comprehensive pest control. In addition, it expands the insecticidal spectrum and reduces Toxicity to humans and animals. emamectin benzoate can enhance the effects of neurotic substances such as glutamate and gamma-aminobutyric acid, thereby causing a large amount of chloride ions to enter nerve cells, causing loss of cell function and disrupting nerve conduction. The larvae will stop immediately after contact. After eating, irreversible paralysis occurs, reaching maximum lethality within 3-4 days. Since emamectin benzoate is tightly bound to the soil, does not leach, and does not accumulate in the environment, it can be transferred through movement and is easily absorbed by crops and penetrates into the epidermis, so that the applied crops have long-term residual effects. A second peak of insecticide mortality occurred over 10 days, and it was rarely affected by environmental factors such as wind and rain.
