Synergistic effects of three synergists on herbicides

  • 摘要: 为研究3种复配增效剂对灭草松、草铵膦、高效氟吡甲禾灵的增效作用及其增效机制,并筛选出表现较好的增效剂,分别测定了以顺丁烯二酸二异辛酯磺酸钠(渗透剂T)、异构醇醚和油酸甲酯为主要成分的3种复配增效剂以及分别添加了这3种复配增效剂的除草剂的静态表面张力(static surface tension,SST)、动态表面张力(dynamic surface tension,DST)、动态干燥度及接触角,并计算了黏附张力及黏附功。理化性能测试显示:以异构醇醚为主要成分的增效剂在降低除草剂的静态表面张力、加速动态表面张力的降低、减小接触角方面表现出的效果最为显著;以渗透剂T为主要成分的增效剂的效果次之;以油酸甲酯为主要成分的增效剂也略有效果,但最不显著。黏附张力及黏附功的数据表明,添加了以异构醇醚为主要成分的增效剂的除草剂药液在叶片上具有更强的黏附,更易在叶表皮持留、润湿。同时,室内药效评价结果也证实了理化性能表现最好的以异构醇醚为主要成分的增效剂添加于除草剂后具有最好的防治效果。
