Product description：

Butachlor is a kind of amide systemic and conductive selective preemergence herbicide, also known as norlachlor, machete, and mediachlor. The pure product is a light yellow oily liquid with a slight aromatic smell. It is hardly soluble in water and easily soluble in many organic solvents. It is chemically stable under normal temperature and neutral and weak alkaline conditions. It will accelerate its decomposition under strong acid conditions, and it can be degraded in the soil Chemicalbook soil. Low toxicity to humans and animals, irritation to skin and eyes, high toxicity to fish. It is mainly absorbed by weed shoots, followed by root absorption. After the plant absorbs butachlor, it inhibits and destroys proteases in the body, affects the formation of protein, and inhibits the normal growth and development of weed sprouts and roots, thereby causing weeds to die.

Physical and chemical properties:

The pure product is a light yellow oily liquid. b.p.156℃/66.66Pa, relative density 1.06～1.07(25℃), decomposition temperature 165℃, vapor pressure 0.6×10^-3Pa(25℃). It is soluble in acetone, ethanol, methanol, benzene and other organic solvents, and its solubility in water is 2mg/L. Good light resistance, thermal decomposition begins at 275°C, unstable at pH 4 or lower.

Usage：

It is a high-efficiency and low-toxic pre-emergence herbicide, mainly used to control most annual gramineous and some dicotyledonous weeds in dryland crops, and control most annual gramineous and some dicotyledonous weeds in dryland crops. It is used to control annual gramineous weeds and some broad-leaved weeds in direct seeding or transplanting rice fields. Also selective for wheat, barley, sugar beet, cotton, peanut and cabbage crops.
