Emamectin, as a new type of antibiotic insecticide, has the advantages of broad spectrum, high efficiency, low toxicity and low residue, and has good insecticidal effect on Lepidoptera pests.

Methyldisulfuron, also known as methanesulfuron, with chemical name of 2 - [(4,6-dimethoxypyrimidine 2-aminocarbonyl) aminosulfonyl] - A - (methylsulfonamido) methyl p-toluidate, is a new sulfonylurea herbicide developed by Bayer company in 2002. As for sulfonylurea herbicides, it is the largest herbicide in the world, It mainly acts by inhibiting acetyllactate synthase, which is absorbed by weed roots and leaves and transmitted in the plant, so as to stop the growth of weeds and achieve the effect of weeding. The agent has good control effect on some broad-leaved weeds such as winter wheat, spring wheat annual gramineous weeds and Zoysia, and the demand for herbicides in China is on the rise.

Cartap is a toxin insecticide of sand silkworm, which has the advantages of high efficiency, broad spectrum, low toxicity and low residue. It has many functions such as internal absorption, stomach toxicity and contact killing. It invades the junction of nerve cells, blocks the acetylcholine secreted by the former nerve cell to transmit to the latter nerve cell, and makes the nerve cell not excited, makes the insect nerve paralyzed, unable to eat, unable to move, stops development, and even dies. It has good control effect on Chilo suppressalis and Chilo suppressalis, and can also control Cnaphalocrocis medinalis, leafhopper, armyworm, Plutella xylostella and Phyllotreta striolata.

The anthelmintic effect of this product is stronger than that of niclosamide.

Enoxolone (Clethodim) has the Chinese trade name of adductor, xylate. Initially reported for its herbicidal activity at the Brighton plantkeeping conference in 1987 by kincadert et al., 1 cyclohexenone based herbicides were first developed by U.S. chevronchemical, Inc. Enoxaparin is a low toxicity herbicide with the following toxicities: acute oral LD50 1630 mg / kg (male), 1360 mg / kg (female) in rats; Mice 2570 mg / kg (male), 2430 mg / kg (female). The action is mainly applied to herbicidal fields of more than 40 crop species including soybean, flax, tobacco, and West melon, but can prevent more than 30 grass weed species including barnyardgrass. The herbicide is an endothermic stem and leaf treatment agent, which is rapidly absorbed by the leaf after treatment and is conducted to the meristem and root, where its cell division is destroyed and the activity of the plant meristem is inhibited, resulting in chlorosis and necrosis of the plant within 1-3 weeks of application, followed by death due to dry leaf blight. The half-life of enoxane in soils is 3-26 D, its duration is short, and it has no effect on stubble crops. Its mechanism of action is the same as that of dilute gramineine, arginyl fluoride graminearum and arginyl graminearum, which are all acetyl CoA carboxylase (ACCase) inhibitors.
