摘　　要：传统的高效氯氟氰菊酯制剂对施药人员的皮肤和眼睛有刺激性,容易引起过敏、中毒反应。为了解决高效氯氟氰菊酯刺激性的问题,笔者利用纳米级功能高分子助剂G-103,制备了纳米助剂包裹的低刺激性的5%高效氯氟氰菊酯悬浮剂。眼部刺激性试验结果表明,5%高效氯氟氰菊酯悬浮剂无刺激性反应。毒力试验结果表明,5%低刺激性高效氯氟氰菊酯悬浮剂24 h和48 h的LC50值分别为8.599 mg/L和7.664 mg/L,显著高于对照组10%高效氯氟氰菊酯悬浮剂(24 h和48 h的LC50值分别为11.050 mg/L和10.270 mg/L),表明G-103包裹提高了高效氯氟氰菊酯悬浮剂的持效性,药效得到了提升。Traditionalλ-cyhalothrin are irritating to the skin and eyes of pesticides users,which can easily cause allergic and toxic reactions.In order to solve this problem,polymer additive G-103 was used to prepare a nanoadditives-wrapped low-irritation 5%λ-cyhalothrin SC.The results of skin and eyes irritation experiments showed that the 5%λ-cyhalothrin SC had no irritation.The results of toxicity test showed that LC50 value of 5%low-irritationλ-cyhalothrin SC at 24 h and 48 h were 8.599 mg/L and 7.664 mg/L,respectively,which was significantly higher than the control group of 10%λ-cyhalothrin SC(LC50 valve at 24 h and 48 h were 11.050 mg/L and 10.270 mg/L,respectively).It is possible that G-103 wrapping improved the persistence ofλ-cyhalothrin,and the efficacy was improved.
