[目的]应用新型药剂18％卷螟杀3号防治稻纵卷叶螟Cnaplocrocis medinalis的田间防治效果,为推广应用提供依据.[方法]采用喷雾法,将18％卷螟杀3号设3个剂量处理30、50、80 mL/666.7 m2,80％敌敌畏80 mL/666.7 m2,25％杀虫双100 mL/666.7 m2,每个处理3次重复,每重复1个小区,每小区面积60m2,各小区随机排列,药后12、24、72 h检查对稻纵卷叶螟幼虫的杀伤效果.[结果]比较18％卷螟杀3号不同使用剂量与对照药剂防治稻纵卷叶螟幼虫的效果,采用DPS法进行差异显著性分析.18％卷螟杀3号80 mL/666.7m2的效果最好,其防效达98.82％,显著高于18％卷螟杀3号50 mL/666.7 m2防效78.62％及80％敌敌畏80 mL/666.7 m2防效72.57％的防治效果.极显著高于18％卷螟杀3号30mL/666.7 m2防效68.52％及25％杀虫双100 mL/666.7 m2防效64.22％的防治效果.[结论]萍乡市三农农资及农业分会联合创制的18％卷螟杀3号是防治稻纵卷叶螟的特效药剂,但对其防机制等尚未进行试验总结,创制新型农药尚有大量的工作量.
