摘要
室内生测结果表明，0．8％阿维菌素微胶囊悬浮剂对斜纹夜蛾、小菜蛾、菜粉蝶的LC50分别为27．72、1．69、0．85mg／L，与乳油剂型的毒力相当。持效性试验结果显示，0．8％阿维菌素微胶囊悬浮剂的持效性要优于乳油剂型，在1～14d内表现尤为明显。对小菜蛾、菜粉蝶的田间药效试验表明，在14．4g／hm2的剂量下，0．8％阿维菌素微胶囊悬浮剂药后7d的防效在89％以上，药后14d防效仍超过80％。持效期为14d左右。
The results of laboratory tests showed that the LC50 of abamectin 0.8% CS against Prodenia litura Fabricius, Pieris rapae （L.）, Plutella xylostella （L.） was 27.72, 1.69 and 0.85 mg/L, respectively, which was approximately equal to the toxicity of abamectin 0.8% EC. The persistence tests showed that the effectiveness of abamectin 0.8% CS was better than that of abamectin 0.8% EC, particularly during 1--14 d. Field trials indicated that, at the dosage of 14.4 g/hm2 , the control efficacy of abamectin 0. 8% CS was over 89% on day 7 and over 80% on day 14 after treatment, and the effectiveness lasted for about 14 d.
