摘要
试验研究了室内、室外不同剂量的克线丹颗粒剂对甘薯茎线虫病的防治效果。室内试验结果表明:各处理中以药土比1∶1200处理防治效果最佳,对甘薯茎线虫的致死率最高,校正死亡率达100%;田间试验结果表明:各处理中以45.0 kg/hm2和37.5 kg/hm2克线丹颗粒剂对甘薯茎线虫病的防治效果最佳,防治效果分别达到了97.68%和91.64%。
The effect of Rugby granular in different dosage on sweet potato stem nematode was tested in indoor and outdoor experiments. The result showed that lethality in dosage of 1 ： 1 200（medicine ： soil）in indoor ones was the highest, the mortality reached 100%. In outdoor, 45.0 kg/hm^2 and 37.5 kg/hm^2, control effect reached 97.68% and 91.64% respectively., were most effective and were the best choices of application in the regions of production of sweet potato in Hebei province.
