不同助剂对甲维盐微乳剂在水稻叶片上附着性能的影响
选用合适的助剂有利于提高农药在水稻叶片上的持留量,解决现有杀虫剂利用率偏低的问题。本文以水稻为试材,测定2.3%甲维盐微乳剂分别与4种农药助剂混用后,其药液表面张力、铺展面积、叶片最大持留量的理化性能差异。结果表明4种助剂均能降低药液表面张力,提高叶片持留量,提高铺展面积。当助剂浓度达到150mg/L后,铺展面积不再增加;200mg/L后,药液表面张力达到最低;300mg/L后,叶面持留量达到最大。其中乳化剂1#表现最优,其次是乳化剂2#,然后是JFC,OP-10。因此,在稻田喷雾中,可利用增加助剂含量来达到降低用药成本和减少环境污染的目的。...

In this paper, the improvement of pesticide utilization on rice leaves by adjuvants was studied. Four kinds of adjuvants were added into the solutions of 2.3% emanectin benzoate ME. The surface tension, spreading area, max retention of the solutions on rice leaves were determined. The results showed that four kinds of adjuvants could reduce the surface tension of solution, increase the retention and spreading area. When the adjuvants concentration was 150 mg/L, the spreading area was no longer increases. When the adjuvants conc |
