Emamectin Benzoate
Carbamate benzoate is a kind of non residual and pollution-free biological pesticide. It has a very high activity to the larvae of Lepidoptera and many other pests and mites. It has both stomach toxicity and contact killing effect. It has a very good effect at a very low dose (0.084 ~ 2G / HA). In addition, it has no harm to the beneficial insects in the process of pest control, which is conducive to the comprehensive pest control. In addition, it is also beneficial to the comprehensive pest control In addition, the insecticidal spectrum is expanded and the toxicity to human and livestock is reduced. Methaamamectin benzoate can enhance the function of neuroplasm, such as glutamate and GABA, so that a large number of chloride ions enter into nerve cells, resulting in the loss of cell function and disruption of nerve conduction. The larvae stop eating immediately after contact, causing irreversible paralysis and reaching the highest lethal rate within 3-4 days. Because of the close combination of abamectin benzoate and soil, it is not leached, nor accumulated in the environment. It can be easily absorbed by crops and permeated into the epidermis through movement and transfer, so that the applied crops have long-term residual effect. The second high peak of insecticidal death rate appears in more than 10 days, and it is rarely affected by environmental factors such as wind and rain.

Hexythiazox
As a growth regulator of thiadiazine insects, thioacaridone has high selectivity, strong contact effect and stomach toxicity. It has good control effect on homopterous planthoppers, leafhoppers, whiteflies and scale hydrocarbon pests, and also has long-lasting larvicidal activity against some coleoptera pests and mites. It can effectively control planthoppers and leafhoppers on rice, leafhoppers on tea, leafhoppers on potatoes, whiteflies on oranges and vegetables, and scale insects and scale insects on oranges. According to the domestic research, it has a certain role of internal absorption and transportation in rice plants. The mechanism of action is to inhibit chitin synthesis and interfere metabolism of insects, so that nymphs can not molt, or molt deformity, or feathering deformity and die slowly, with high nymph killing activity. Generally, the recommended dose can not directly kill the adults, but can reduce egg laying, egg hatching rate and life span. Generally, the effect can be seen only 3-7 days after the application of the medicine. It has no direct killing power to the adults, but it can shorten their life span, reduce their oviposition, and produce mostly sterile eggs. Even if the larvae hatch, they will die soon. It has good control effect on Hemiptera, leafhoppers, whiteflies and scale insects, and the effective period is more than 30 days. It is safe to natural enemies, and there is no cross resistance between thiaacaridone and other insecticides. The effect of the drug is slow, and the pest can be controlled 3-7 days after application. When the density of insect population is high, it should be mixed with quick acting agents.
Imidacloprid
Imidacloprid, also known as mimaphid, piriujing, chlorpyrifos and Bidan, is a kind of high-efficiency and broad-spectrum insecticide with stomach toxicity and contact killing effect. It has a long period of efficacy and has a good control effect on the insect pests of the bayonet mouthparts. The drug is a new structure compound. Its action point in insect body is nicotinic acid acetylcholinesterase receptor, which interferes with the motor nervous system of insect. This mechanism is completely different from the traditional insecticide, so it has no cross resistance. The medicine is mainly used to control the thorn sucking mouthparts pests on rice, wheat, cotton and other crops.
