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。
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.
