摘　　要：本试验以小麦根腐病常用防治药剂30g/l苯醚甲环唑悬浮种衣剂为对照,研究了25g/l咯菌腈悬浮种衣剂对小麦根腐病的田间防病效果。结果表明:25g/l咯菌腈悬浮种衣剂5g/100kg的防效和对照药剂30g/l苯醚甲环唑悬浮种衣剂在小麦抽穗期的防效无显著性差异,分别为83.78%和81.78%。表明25g/l咯菌腈悬浮种衣剂对小麦根腐病具有较好的防治效果,对作物安全,可在生产中推广使用。In this study, 25% fludioxonil FSC agaist wheat root rot was studied on field. Theresults showed that the control effects of 25% fludioxonil FSC with doses of 5 g/100 kg,the control effect was equivalent to that of 30% difenoconazole FSC.It showed that 25% fludioxonil FSC had good control effect on wheat root rot, safety for crops and could be popularized and used in production.
