| 摘 要： | 2007-2008年，应用氯虫•噻虫嗪不同剂型防治水稻二化螟、稻纵卷叶螟的田间试验结果表明：0.6%氯虫•噻虫嗪颗粒剂对二化螟的效果较好，但难以控制稻纵卷叶螟危害；40%氯虫•噻虫嗪水分散粒剂可有效防控以上2种虫害且持效期长达30 d。同一时期同等剂量下，各施用1次0.6%氯虫•噻虫嗪颗粒剂、40%氯虫•噻虫嗪水分散粒剂，前者撒施处理对其药效均显著低于后者茎叶喷雾处理。

| Abstract: | Field experiments were conducted to control Chilo suppressalis and Cnaphalocrocis medinalis with different formulations of chlorantraniliprole•thiamethoxam in 2007-2008. The results showed that C. suppressalis was obviously controlled by 0.6% chlorantraniliprole•thiamethoxam GR, but C. medinalis could not be. However, perfect control of them could be achieved with 40% chlorantraniliprole•thiamethoxam WG (48.0 g/hm2) within 30 d after treatment. When similar doses of 0.6% chlorantraniliprole•thiamethoxam GR and 40%WG were applied during the same period, the control efficacy of the former was significantly lower than that of the later one. |
