Physical and chemical properties: the technical drug is white or light yellow slice and powder, melting point 59.3 ℃, vapor pressure 0.0053 MPa (20 ℃). The solubility in water at 20 ℃ is 2.5 mg / L, which is soluble in most organic solutions.
Action characteristics: the herbicide is a chiral fluorophenoxycarboxylic acid herbicide, which is relatively stable in acid medium and hydrolyzed in alkaline medium. Acetochlor is a kind of acetophthalein coenzyme carboxylase inhibitor. It is absorbed by the leaves and sheaths of plants. It is conducted by phloem and accumulated in the meristem of plants. It inhibits the carboxylase of phthalein coenzyme and stops the synthesis of fatty acids. The growth and division of cells can not be carried out normally, and the lipid-containing structure such as membrane system is destroyed, which finally leads to plant death.
Application：it is mainly used to control weeds in wheat field, and has control effect on annual gramineous weeds such as wild oats, Lolium aestivum, durum, Hedysarum, Lolium.
