| 中文摘要: |
| 针对5%甲维盐微乳剂利用率偏低的问题，筛选了增效作用显著、安全性高且持留量好的配方。通过筛选不同溶剂、助剂与测定其药液表面张力、铺展面积、叶片最大持留量等理化性能差异，研发出5%甲维盐微乳剂最佳配方。5%甲维盐微乳剂最佳配方为：甲维盐5%、乙醇25%、环己酮5%、602 5%，快速渗透剂T 4%，环氧大豆油3%，丙三醇3%，1#乳化剂20%，去离子水补足至100.0%。所制备的制剂性能稳定，质量可靠，各指标均符合微乳剂的相关标准要求。同时，田间防治效果表明，该制剂对月季Rosa chinensis（Jacq）上蓟马具有很好防治效果，优于市售的5%甲维盐微乳剂，对农药微乳剂配方开发具有借鉴作用。 |
| 英文摘要: |
| According to the low utilization at present of 5% emamectin benzoate microemulsion, the formula of this product with obvious synergistic effect, high safety and max retention of the solutions were selected in the process of compounding additives. The optimum formula of 5% emamectin benzoate microemulsion was developed through screening the different solvents, different adjuvants and determining difference in physical and chemical properties of the surface tension, spreading area, max retention of the solutions, etc. The optimal formula of 5% emamectin benzoate microemulsion was as follows: Emamectin benzoate 5%, alcohol 25%, cyclohexanone 5%, 6 025%, rapid penetrant T 4%, epoxidized soybean oil 3%, glycerol 3%, 1# emulgator 20% and deionized water up to 100.0%. All specifications of the formulation were with a good quality meets the requirements of microemulsion. At the same time, the results of control effects showed that it had a good control effects against thrips on Rosa chinensis. It was better than others commercial 5% emamectin benzoate microemulsion. It could provide reference for developing pesticide microemulsion formula. |
