在室内对扶桑绵粉蚧分别进行了土壤药剂处理和熏蒸处理试验。结果表明,土壤处理效果均效差的8种药剂毒力最高的为480g/L毒死蜱乳油,防治效果40.24%。熏蒸处理供试的5种药剂对扶桑绵粉蚧的毒力作用最大的为40%丙溴磷乳油。从施药方法上比较,熏蒸处理的防效要明显好于土壤处理,其中40%丙溴磷乳油和42%阿维·毒死蜱乳油的熏杀效果明显,防治效果可达97.8%和91.1%。
In the laboratory Fusong mealybugs soil pesticide treatment and fumigation treatment were tested. The results showed that the highest toxicity of 8 pesticides with the same effect of soil treatment was 480g / L chlorpyrifos and the control effect was 40.24%. Fumigation treatment for the test of the five agents on the toxicity of Fusong mealybugs the largest 40% of profenofos EC. Compared with the application method, fumigation treatment was significantly better than the soil control effect, of which 40% profenofos and 42% Avicel chlorpyrifos significantly smoked effect, control effect of up to 97.8% and 91.1%.
