5种组合药剂不同配比防治黑松松针盾蚧对比试验

Comparative Experiment on the Control of Pinus thunbergii Fiorinia japonica Kuwana With Five Different Combinations of Pesticides and Different Ratios

通过对40%氧乐果乳油(omethoate)+480g/L吡虫啉悬浮剂(imidacloprid)、45%马拉硫磷乳油(malathion)+480g/L吡虫啉悬浮剂、45%毒死蜱乳油(chlorpyrifos)+5%啶虫脒乳油(acetamiprid)、4.5%高效氯氰菊酯乳油(beta cypermethrin)+480g/L吡虫啉悬浮剂、50%敌敌畏乳油(dichlorvos)+5%啶虫脒乳油5种组合药剂不同配比防治黑松松针盾蚧的防治效果进行了分析,结果表明:45%毒死蜱乳油+5%啶虫脒乳油(3∶2)防治效果最好,其次为50%敌敌畏乳油+5%啶虫脒乳油(3∶2),最差为4.5%高效氯氰菊酯乳油+480g/L吡虫啉悬浮剂(1∶1)。

By comparing 40% Omethoate+480g/L Imidacloprid suspension,45% malathion+480g/L Imidacloprid suspension,45% Chlorpyrifos+5% acetamiprid suspension,4.5% Beta cypermethrin+480g/L Imidacloprid suspension and 50% Dichlorvos EC+5% Acetamiprid EC,the control effect of five kinds of combination agents with different proportions on Pinus thunbergii Fiorinia japonica Kuwana was analyzed.The experimental results showed that 45% Chlorpyrifos EC+5% Acetamiprid EC(3∶2)had the best control effect,followed by 50% Dichlorvos EC+5% Acetamiprid EC(3∶2).The worst is 4.5% Beta cypermethrin+480g/L Imidacloprid suspension(1∶1).
