摘要
在糯玉米吐丝期,开展了6种药剂喷灌"4腋1顶"防治糯玉米田玉米螟的田间药效试验,结果表明,喷灌25 g/L多杀菌素悬浮剂800倍液、2.2%甲氨基阿维菌素苯甲酸盐微乳剂1 500倍液、1.8%阿维菌素乳油1 500倍液、46%杀单.苏云菌可湿性粉剂600倍液和15%茚虫威悬浮剂2 000倍液,雌穗被害率均被控制在3%以下,防治效果达95%以上。建议生产上优先选用这些药剂用于糯玉米田玉米螟的防治。
The experiment explored the efficiency of six pesticides for corn borer in waxy corn field at silking stage by adopting the sprinkling irrigation method.The results showed that： the percentage of damaged female ear applied with 25 g/L spinosad SC 800 times diluted,2.2% emamectin benzoate ME 1 500 times diluted,1.8% avermectin EC 1 500 times diluted,46% monosultap · Bt WP 600 times diluted and 15% indoxacarb SC 2 000 times diluted were lower than 3%,and the control effect was over 95%.The six pesticides were recommended for corn borer control in waxy corn field.
