摘要
选用16%吡虫.噻嗪酮WP、25g/L多杀霉素SC、20%吡虫啉SL、20%甲维.丙溴磷EC、20%高氯.马WP和200g/L氯虫苯甲酰胺SC等6种杀虫剂对烟粉虱进行田间防治试验。结果表明：20%甲维.丙溴磷EC、20%高氯.马WP和25g/L多杀霉素SC对烟粉虱有较好防效,药后10d防效均在80%以上;20%吡虫啉SL和200g/L氯虫苯甲酰胺SC对烟粉虱防效一般,药后10d防效在70.09%～76.92%;16%吡虫.噻嗪酮WP对烟粉虱防效较低。
Abstract
Insecticides of 16% imidacloprid thiazide ketoneWP, 25g/L spinosadSC, 20% imidaclopridSL, 20% emamectin benzoate profenofosEC, 20% lambdaeyhalothrin malathionWP and 200g/L chlorantraniliproleSC were selected for evaluating the control efficiency against Bemisa babaci in the field environment. The results showed that pesticide preparations of 20% emameetin benzoate profenofos EC, 20% lambdaeyhalothrin malathionWP and 25g/LspinosadSC were ideal to control B. babaci 10 days after the spraying, the field control efficiency was over 80% at a dose of 40g/667m^2, 33 g/667m^2 and 66mL/667m62 respectively. In the second place, 20% imidaclopridSL and 200 g/Lchloantraniliprole SC had an ordinary effect to control B. babaci, and the field control efficiency was between 70.09% to 76.92% at lOdays after spraying. The re- search also indicated that 16% imidacloprid thiazide ketoneWP was inferior to inhibit the number of B. babaci.
