摘要
研究了甲氨基阿维菌素苯甲酸盐及其复配剂对稻纵卷叶螟的田间防效。试验结果表明,1.9%~5%甲氨基阿维菌素苯甲酸盐对稻纵卷叶螟具有良好的防治效果,每公顷施用5.7~9g,杀虫防效可达82.7%~94.0%,保苗防效达87.5%~92.7%。每公顷同剂量的甲氨基阿维菌素苯甲酸盐再加入240g毒死蜱混合使用,即可杀死高龄幼虫,防效还可提高3个百分点以上。
The field efficacy test results indicated that 1.9%-5% emamectin benzoate had good prevention and control effects on Cnaphalocrocis medinalis. The insect prevention and control effect was 82.7%-94.0%, and seedling protection effect was 87.5%-92.7% at application rate of 5.7-9 g/ha. The same dosage of emamectin benzoate plus 240g/ha of chlorpyfifos was able to kill the old-age larva, and increased the efficacy by 3%.
