两种杀虫剂防治茶尺蠖药效试验初报

摘要

田间试验结果表明,24％艾法迪悬浮剂、15％凯恩乳油对茶尺蠖(Ectropis oblique Prout)具有较好的速效性和较长的持效期,24％艾法迪悬浮剂1 500 mL/hm2及15％凯恩乳油333.3 mL/hm2的防治效果明显高于对照药剂2.5％联苯菊酯乳油1 350 mL/hm2,是防治茶尺蠖的理想药剂,可以大面积推广使用.%Field test results showed that there was better quick effect and longer duration to prevent and cure Ectropis oblique Prout for 24％ Cyanide fipronil hydrazone SC and 15％ Indoxacarb EC.The prevent and cure effect of 24％ Cyanide fipronil hydrazone SC with 1 500 mL/hm2 and 15％ Indoxacarb EC with 333.3 mL/hm2 was significantly higher than of 2.5％Bifenthrin EC with 1 350 mL/hm2,thus 24％ Cyanide fipronil hydrazone SC and 15％ Indoxacarb EC was very good pesticide to prevent and cure E.oblique Prout,could be popularized and apply in large scale.
