研究5%高效氯氟氰菊酯水乳剂、10%联苯菊酯乳油、45%毒死蜱乳油、15%阿维·三唑磷乳油四种化学农药在茶叶上农药残留的残留动态变化及安全间隔期。试验结果表明:施用5%高效氯氟氰菊酯、10%联苯菊酯和15%阿维·三唑磷处理防治效果达极显著水平,施用45%毒死蜱处理达到显著水平。建议在茶园中施用杀虫剂时,选用高效氯氟氰菊酯和联苯菊酯两种低毒低残留农药,茶园里慎用毒死蜱和三唑磷。 To study the dynamic changes and safety intervals of pesticide residues in tea leaves of four chemical pesticides, including 5% lambda-cyhalothrin emulsion, 10% bifenthrin EC, 45% chlorpyrifos EC and 15% period. The results showed that the control effect of 5% lambda-cyhalothrin, 10% bifenthrin and 15% avithot-triazophos reached the extremely significant level, and the treatment with 45% chlorpyrifos reached a significant level. Proposed pesticide application in the tea garden, the choice of lambda-cyhalothrin and bifenthrin two low toxicity and low residual pesticides, chlorpyrifos and triazophos caution in the tea garden.
