- 摘要:
- 以蛇床子素原药为试材,以外观、热贮冷贮稳定性、粒径、pH、分散性为评价指标,考察水乳剂配方中的乳化剂、增稠剂、防冻剂的最佳用量及最佳制备工艺,研制新型环境友好型农药制剂5%蛇床子素-多杀菌素水乳剂。结果表明:5%蛇床子素-多杀菌素水乳剂的较优处方为蛇床子素 4.93%、多杀菌素0.07%、丙酮 5%、Tween-20 1.5%、Span-20 3.5%、黄原胶0.15%、乙二醇4%、有机硅油0.2%,超纯水补至100%;该处方制备所得水乳剂热贮冷贮稳定,各项指标均符合要求,模拟室内粮仓试验结果表明对谷蠹、玉米象、赤拟谷盗的防治效果显著;用该处方工艺制备所得5%蛇床子素-多杀菌素水乳剂的各项指标均符合质量标准,且具有一定的应用价值和经济效益。
- Abstract:
- The purpose of this study was to develop a kind of environment friendly pesticide formulation-5% osthole-spinosad emulsion in water.According to the performance index,stability of the formulation under hot and cold storage,particle size,pH,dispersibility.This study investigated the effect of different substances on the 5% osthole-spinosad EW systematic stability from the macroscopical angel.The results showed that,the experiment finally confirmed the excellent prescription of 5% osthole-spinosad EW.The main conclusion obtained were listed as follows,osthole(4.93%),spinosad(0.07%),acetone(5%),tween-20(1.5%),span-20 (3.5%),xantham gum(0.15%),ethylene glycol(4%),defoamer(0.2%),water(80.65%).This formulation obtained in this study,the indexes of the 5% osthole-spinosad EW were all up to the standards and the emulsion in water should be further studied.
