Can Jiawei salt remove rice?

Methamectin is a new type of highly efficient semisynthetic antibiotic insecticide synthesized from the fermentation product avermectin B1. It has the characteristics of ultra-high efficiency, low toxicity (preparation is nearly non-toxic), no residue, no pollution and other biological pesticides. Compared with avermectin, its insecticidal activity is increased by 1-3 orders of magnitude, and it has extremely high activity against Lepidoptera larvae and many other pests and mites. It has both stomach toxicity and contact toxicity. It has a very good effect at a very low dose (0.084~2g/ha), and it does no harm to beneficial insects in the process of pest control, which is conducive to the integrated control of pests. In addition, it expands the insecticidal spectrum and reduces the toxicity to humans and animals.

(1) applicable crops: tocopherol salt is highly safe for all crops in protected areas or 10 times the recommended dose, and has been used in many food and cash crops in western countries. Considering that it is a rare green pesticide. China should first use it to control insect pests on cash crops such as tobacco, tea, cotton and all vegetable crops.

(2) Mechanism of action: methamyl salt can enhance the effect of neuroticism such as glutamate and gamma-aminobutyric acid (GABA), which makes a large amount of chloride ion enter nerve cells, lose cell function, disrupt nerve conduction, larvae stop eating immediately after contact, occur irreversible paralysis, and reach the highest fatality rate within 3-4 days. Because it binds closely to soil, does not leach and does not accumulate in the environment, it can be easily absorbed by crops and infiltrated into the epidermis through Translaminar movement, so that crops have long-term residual effect, and the second peak of insecticidal mortality occurs in more than 10 days, and is rarely affected by environmental factors such as wind, rain and so on.

(3) Pest control: carbaryl salt has incomparable activity to many pests, especially to Lepidoptera, Diptera and thrips, such as red leaf roll moth, tobacco aphid armyworm, cotton bollworm, tobacco armyworm, diamondback moth, beetle, dryland night moth, Spodoptera litura, cabbage armyworm, vegetable powder butterfly, cabbage borer, cabbage striped borer, tomato moth, potato beetle, Mexican ladybug, etc.
