[目的]研究2%高渗吡虫啉颗粒剂防治烟草蚜虫的最佳使用剂量和防治效果.[方法]采用随机区组试验设计,施用2%高渗吡虫啉颗粒剂3.75、6.00、7.50 kg/hm2、15%涕灭克颗粒剂15 kg/hm2和空白对照(CK)共5个处理,进行效果对比试验.[结果] 距施药期20、27、34、41、48 d蚜量调查时:处理A的防效分别为50.70%、61.20%、77.94%、85.08%、96.00%;处理B的防效分别为59.96%、75.48%、94.34%、100.00%、100.00%;处理C的防效分别为66.60%、81.45%、98.48%、100.00%、100.00%;对照药剂15%涕灭克颗粒剂的防效分别为61.30%、70.34%、82.91%、66.56%、66.20%.7.5 kg/hm2的防治效果在各个调查时期都高于其他处理. [结论] 2%高渗吡虫啉颗粒剂的持效性比15%涕灭克颗粒剂长,使用安全,可大面积推广使用.推荐2%高渗吡虫啉颗粒剂的施用量应为6.0~7.5 kg/hm2.
[目的]研究2%高滲吡蟲啉顆粒劑防治煙草蚜蟲的最佳使用劑量和防治效果.[方法]採用隨機區組試驗設計,施用2%高滲吡蟲啉顆粒劑3.75、6.00、7.50 kg/hm2、15%涕滅剋顆粒劑15 kg/hm2和空白對照(CK)共5箇處理,進行效果對比試驗.[結果] 距施藥期20、27、34、41、48 d蚜量調查時:處理A的防效分彆為50.70%、61.20%、77.94%、85.08%、96.00%;處理B的防效分彆為59.96%、75.48%、94.34%、100.00%、100.00%;處理C的防效分彆為66.60%、81.45%、98.48%、100.00%、100.00%;對照藥劑15%涕滅剋顆粒劑的防效分彆為61.30%、70.34%、82.91%、66.56%、66.20%.7.5 kg/hm2的防治效果在各箇調查時期都高于其他處理. [結論] 2%高滲吡蟲啉顆粒劑的持效性比15%涕滅剋顆粒劑長,使用安全,可大麵積推廣使用.推薦2%高滲吡蟲啉顆粒劑的施用量應為6.0~7.5 kg/hm2.

[Objective] The purpose was to study the optimum dosage and control effect of 2% high penetration imidacloprid granules on Myzus persica (Sulzer). [Method] In the comparison experiment with randomized block design, 5 treatments of application 2% imidacloprid granules 3.75, 6.00 and 7.50 kg/hm2, 15% aldicarb granules 15 kg/hm2 and CK were set up to study their efficacy in field.[Result] On the 20th day, 27th day, 34th day, 41th day and 48th day after application, the control effects of treat A were 50.70%, 61.20%, 77.94%, 85.08% and 96.00%;the control effects of treat B were 59.96%, 75.48%, 94.34%, 100.00% and 100.00%;the control effects of treat C were 66.60%, 81.45%, 98.48%, 100.00% and 100.00%;the control effects of treat D were 61.30%, 70.34%, 82.91%, 66.56% and 66.20%.The control effects of 7.50 kg/hm2 were higher than other treats.[Conclusion] The effect of holding of 2% imidacloprid granules was more than 15% of aldicarb granules. And it could use safety and promote the use of a large area. The author recommended 2% hypertonic imidacloprid granules should be 6.0-7.5 kg/hm2.
