S-Metolachlor is mainly absorbed and transmitted upward through the base and bud of weeds. It inhibits the synthesis of protein in germinated seeds, inhibits choline infiltration and interferes with the synthesis of egg fat, so as to inhibit the growth of buds and roots. Weeds are killed in the bud to achieve the purpose of weed control. It can be applied to soybean, corn, cotton, cotton and other crop fields, and can prevent and control horse Tang, barnyardgrass As one of the most important herbicides used in many crops, weeds such as beef tendon grass and golden dog tail grass also have certain effects on broad-leaved weeds such as purslane and vegetable searching.

Acrylonitrile is an important monomer of synthetic fiber, synthetic rubber and synthetic resin. Polyacrylonitrile fiber (acrylic fiber) is made from acrylonitrile. Its performance is very similar to wool, so it is also called (synthetic wool). Nitrile rubber can be prepared by copolymerization of acrylonitrile and butadiene. It has good oil resistance, cold resistance, wear resistance and electrical insulation, and its performance is relatively stable under most chemical solvents, sunlight and heat. ABS resin prepared by copolymerization of acrylonitrile with butadiene and styrene has the advantages of light weight, cold resistance and good impact resistance. Acrylamide, acrylic acid and their esters can be prepared by hydrolysis of acrylonitrile. They are important organic chemical raw materials. Acrylonitrile can also be prepared by electrolytic hydrogenation coupling to produce adiponitrile, and hexanediamine can be prepared by hydrogenation of adiponitrile. Hexanediamine is the raw material of nylon 66. It can be used to make water-resistant agent and adhesive, also used in other organic synthesis and pharmaceutical industries, and used as grain fumigant. In addition, this product is also an aprotic polar solvent.

Enoylmorpholine is a morpholine broad-spectrum bactericide. It has a unique mode of action on the fungi of Botrytis and Phytophthora, mainly causing the decomposition of sporangium wall and cell death. Except zoospore formation and spore swimming stage, it plays an important role in all stages of the life cycle of oomycetes. The drug has strong internal absorption. When applied to the root, it can enter all parts of the plant through the root; When sprayed on the leaf surface, enoylmorpholine can also enter the inside of the leaf to prevent and control the bacteria that have invaded the plant in time. At the same time, it also has an ideal protective effect on the new leaves; It contains two active ingredients. After application, it can form a strong and effective protective film on the crop surface at the same time, thus showing the excellent effects of internal treatment and external protection. It is especially effective against downy mold, Phytophthora and Pythium. It can be used in grapes, peppers, cucumbers, tobacco, potatoes, cruciferous vegetables and tomatoes.

Tebufenozide is an insect growth regulating insecticide with high efficiency and low toxicity. It has special effects on Lepidoptera insects and larvae, and has a certain effect on selective Diptera and Daphnia insects. It can be used for vegetables (cabbage, melon, eggplant, etc.), apple, corn, rice, cotton, grape, kiwi, sorghum, soybean, sugar beet, tea, walnut, flowers and other crops. It is a safe and ideal medicine.

Chlorendic acid, or 1,4,5,6,7,7-hexachlorobicyclo[2.2.1]-hept-5-ene-2,3-dicarboxylic acid, is a chlorinated hydrocarbon used in the synthesis of some flame retardants and polymers. It is a common breakdown product of several organochlorine insecticides.
