摘要
[目的]研究60%吡虫啉SC种衣剂拌种对水稻苗期害虫的防治效果及秧苗素质的影响。[方法]设4个处理,于水稻秧田期进行拌种处理。[结果表明]60%吡虫啉SC种衣剂对秧田灰飞虱和蓟马具有较好的防治效果,1kg稻种拌60%吡虫啉SC种衣剂5ml对灰飞虱揭膜后20d的防效在85.51%,对蓟马的防效在90%以上,控制期长达30 d以上,且对水稻秧苗素质的提高有明显作用。[结论]60%吡虫啉SC种衣剂是秧田期控制灰飞虱和蓟马为害的理想药剂。
[ Objective ] The aim was to study control effect and the quality of rice seedling of 60% imidacloprid seed coating on insect pest in rice seedling stage. [ Method] Seed dressing treatment was carried out in rice seedling stage by setting up four treatment. [ Result] The result showed that 60% imidaeloprid seed coating had better control effect on WBPH and Rice Thrip. Control effect of WBPH reached 85.51% after removing film 20d by 1 kg rlce mixing with 60% imidacloprid SC 5 ml. The control effect of thrips reached more than 90% , and the control period was more than 30 d, and there was apparent effect on the improvement of rice seedling quality. [ Conclusion] 60% imidacloprid SC was ideal pharmaceutical of control of WBPH and rice thrip in rice seedling stage.
