新型乳油配方及在甜菜安复配乳油中的应用

New Type of EC Formula and the Application in Desmedipham Mixture

[目的和方法]基于甜菜安、甜菜宁、精喹禾灵的化学性质,用溶剂-表面活性剂共享系统开发了上述3者的新型复配乳油配方。[结果]新配方在自动分散性上表现优良,稳定性符合国家产品标准要求,对禾本科和阔叶杂草的都有较高防效。[结论]溶剂-表面活性剂共享系统的开发取代了苯类和异氟尔酮、N-甲基吡咯烷酮等高风险有机溶剂在传统乳油中的应用,对当前环保型乳油制剂的发展具有推动作用。

[Aims a nd Me thods] Based on the chemical property of desmedipham, phenmedipham and quizalofop-p-ethyl,new type of desmedipham·phenmedipham·quizalofop-p-ethyl emulsifiable concentrate formula was developed by using solvent-surfactant sharing system. [Re s ults ] The emulsifiable concentrate has good dispersion and qualified stability, which meet our country’s requirement, and has better efficiency against broadleaf and grass weeds than the control. [Conclus ions ] The solvent-surfactant sharing system developed can replace the organic solvents with high risk such as benzene, isophoron and N-methyl pyrrolidone applied in traditional emulsifiable concentrate products, and promote the development of environment-friendly emulsifiable concentrate.
