摘要
经用4种农药对湿地松粉蚧进行林间注干试验,结果表明:杀扑磷防效最高,与其他3种农药防效间存在明显差异;经对杀扑磷3种浓度下防效方差分析可知,杀扑磷在50倍浓度下防效为67.89%,表现最好。
In the experiment, 4 kinds of chemical pesticides were used on Oracella acuta by injecting trunk. The results showed that the control efficacy of methidathion on O. acuta was the best, different from other pesticides significantly. The variance analysis of control efficiency of three concentrations of chemical pesticides indicated that methidathion at 50 times had the excellent control effect, which was 67.89%.
