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。
2007-2008, the application of chlorine pesticides thiamethoxam different formulations of rice stem borer, rice leaf roller results showed that: 0. 6% chlorine insects thiamethoxam granules on the Chilo suppressalis better, But it is difficult to control the damage of rice leaf roller; 40% of chlorine insects. Thiamethoxam water dispersible granules can effectively control the above two pests and the persistence of up to 30 d. In the same period of the same dose, each application of 0.6% chlorine insecticide. Thiamethoxam granules, 40% chlorine insecticide. Thiamethoxam water dispersible granules, the former sprinkling treatment of its efficacy were significantly lower than the latter stems and leaves Spray treatment.
