树干注药法防治春尺蛾试验研究

为了有效防治春尺蛾，明确树干注药法对春尺蛾幼虫的防治效果，选用5%啶虫脒乳油、40%氧乐果乳油、30%乙酰甲胺磷乳油和10%吡虫啉可湿性粉剂4种常用高效内吸传导性药剂，配置成不同浓度，采取树干打孔注药法进行防治春尺蛾幼虫药效试验。试验表明，树干打孔注射4种药剂对春尺蛾幼虫均有一定防治效果，40%氧乐果原液和30%乙酰甲胺磷原液防治效果最好，处理后3天、7天防治效果分别达到74.6%和75.33%、99.31%和100%，与其他药剂处理存在极显著差异。

Experimental research on trunk injection controlling Apocheima cinerarius Erschoff

The paper aims to control Apocheima cinerarius Erschoff efficiently,and clarify the effect of the trunk injection.4 intake transportation function insecticides (5% acetamiprid EC, 40% omethoate EC, 30% acephate EC and 10% imidacloprid WP) were selected in the control of Apocheima cinerarius Erschoff with trunk injection. The results showed that 4 insecticides exhibited determinate efficiency, and the control efficiency of 40% omethoate and 30% acephate concentrate were the obvious highest, 3 days after the application it was 74.6% and 75.33%, 7 days after the application it was 99.31% and 100%.
