Abstract

The invention relates to a herbicide composition, in particular to a herbicide composition taking an oleic acid alcohol ester-containing surfactant as a stabilizer and synergist. The herbicide composition comprises the following components in percentage by weight: 1-95% of an active component, 1-10% of an oleic acid alcohol ester-containing surfactant as a stabilizer and synergist, and the balance of other components, totaling 100%. The active component is a composition of clomazone. The clomazone weeding composition taking the oleic acid alcohol ester-containing surfactant as a stabilizer and synergist has stable physical and chemical properties, is qualified in various detection indexes within the shelf life of the product, and is free of crystallization and caking in 90 days at the temperature of -18 DEG C. A preparation of the weeding composition is mainly used for preventing and controlling annual gramineous weeds and broadleaf weeds in soybean, peanut, sugarcane, rape, potato and rice fields.

Description

technical field [0001] The invention relates to a herbicidal composition, in particular to the application of an oleic acid alcohol ester surfactant. [0002] A herbicidal composition comprising a clomazone composition and an oleic acid alcohol ester surfactant as a stabilizer and synergist and its application. Background technique [0003] Clomazone is an organic heterocyclic selective pre-emergence herbicide first developed by FMC. Its English name is clomazone, and its structural formula is as follows: [0004] [0005] Chemical name: 2-(2-chlorobenzyl)-4,4-dimethylisoxazol-3-one; Molecular formula: C 12 h 14 ClNO 2 , Molecular weight: 239.7, the original drug is a light brown viscous liquid with a relative density of 1.192 and a vapor pressure of 19.2MPa at 25°C. The solubility in water is 1.1g / L, easily soluble in acetone, acetonitrile, chloroform, cyclohexanone, dichloromethane, methanol, toluene and other organic solvents. It is stable in alkaline and acidic (...
