15%甲维盐微乳剂飞防专用药的制备

Preparation ofspecial aviation plant protection formulation for 15% methyl sulphate microemulsion

为了制备高效飞防药剂-15%甲维盐微乳剂,对配方中的溶剂、防冻剂、乳化剂、水质进行研究,最终确定15%甲维盐微乳剂最优配方为:15%甲维盐,20%的DMP,8%甲醇,w(乳化剂7211):w(600号):w(有机硅)=6∶3∶4,防冻剂3%,自来水补足100%.通过最优配方所制备的甲维盐微乳剂各项性能良好,符合标准要求;室内毒力实验表明,药剂杀小菜蛾的高峰时间为第2d前后,并且对其有显著的防治效果.15%甲维盐微乳剂应用于无人机飞防用药,具有良好的开发和应用前景.

In order to prepare high-efficiency anti-agent-15% avidin microemulsion,the solvent,antifreeze,emulsifier and water quality in the formula were studied.The optimal formula of 15% emamectin benzoate salt microemulsion was finally determined:15%emamectin benzoate,DMP 20%,8% methanol,7211 emulsifier∶600# organosilicon=6∶3∶4,antifreeze3%,tap water to make up 100%.The N-dimensional salt microemulsion prepared by optimal formula has good performance and meets with standard requirements;the indoor virulence experiment shows that the peak time of the pesticide killing Plutella xylostella is around the 2nd day,and it has significant control effect on diamondback moth.15% emamectin benzoate salt microemulsion is applied to UAV flying anti-drug,which has good development and application prospects.
