【摘要】 对比了1%血根碱·藜芦碱可溶液剂与哒螨灵、藜芦碱对枣树山楂叶螨的防治效果。实验结果表明:与哒螨灵相比,1%藜芦碱·血根碱可溶液剂对枣树山楂叶螨的速效性一般,但持效性明显,质量浓度为5～10mg/L时,施药后1d的防效为40.24%～68.57%,均显著低于哒螨灵的84.77%;施药后7d的防效为92.78%～97.93%,均优于哒螨灵的91.62%,10mg/L处理施药后7天的防效高于哒螨灵6%以上,差异显著。同等质量浓度10mg/L下,1%藜芦碱·血根碱可溶液剂施药后1、3、7d的防效均略优于对照药剂0.5%藜芦碱可溶液剂,且安全性高,值得推广使用。更多还原

【Abstract】 The control effects of 1% sanguinarine and veratridine SL against tetranychus viennensis were determined and compared with those of pyridaben and veratridine. The results showed that 1%sanguinarine and veratridine SL didn’ t perform better in the quick effect,but was superior in the lasting effect compared with pyridaben. The control effect of 40. 24% ～ 68. 57% was significantly lower than that of pyridaben 84. 77% on 1 d after application under the application concentration of5 ～ 10 mg/L. However,the control effect increased to 92. 78% ～ 97. 93% on 7 d after application,better than that of pyridaben 91. 62%. And the difference of the control effect was up to 6% under the application rate of 10 mg/L after 7 days of the application. Under the same application rate,1%sanguinarine and veratridine SL also showed a slightly higher control effect than that of the control agent 0. 5% veratridine SL on 1,3 and 7 d after application,and higher safety,which demonstrated a value to be promoted for application.更多还原
