摘　　要：甜菜立枯病病原菌在高温高湿条件下以Pythiumdebaryanum为主 ,其次为Rhizoctoniasolani,在低温干旱条件下以Fusariumsolani为主 ,其次为R.solani。不同杀菌剂对甜菜立枯病主要致病菌的抑菌效果不同 ,通过农药的合理混配可明显提高防病效果。二元混配制剂L1、三元混配制剂S6 处理甜菜种子 ,甜菜立枯病病情指数显著低于福美双处理 ,对甜菜立枯病防效高。Pathogenetic fungi Pythium debaryanum is the key and 2nd is Rhizoctonia solani which under the high temperature and high humidity conditions, and Fusarium solani is the key and 2nd is Rhizoctonia solani which under the low temperature and dry season. For sugarbeet damping-off controlling,we need different chemicals,we have found that the seeds treated with two or three chemicals mixtured could be got good results, that′s L1 with two chemicals and three chemicals with S6 added which based on L1,the effect is better than TMTD, the disease index very low.
