摘　　要：本文采用菌丝生长速率法,测定4种杀菌剂对天津地区草莓镰刀根腐病菌的室内毒力。结果表明,咯菌腈、氟啶胺、多菌灵和啶氧菌酯对天津地区草莓根腐病菌菌株的EC50值范围分别为0. 020 5~5. 920 8μg/m L、0. 055 7~0. 556 0μg/m L、0. 064 3~4. 192 6μg/m L和3. 862 3~151. 273 9μg/m L,供试菌株对4种杀菌剂敏感性的地区性差异不明显,但同一地区不同菌株间的敏感性差异较大。The laboratory toxicities of 4 fungicides against Fusarium oxysporum on strawberry root in Tianjin were determined according to mycelia growth rate method. The results showed that EC50 values of fludioxonil,fluazinam,carbendazim and picoxystrobin against 9 tested isolates of Fusarium oxysporum ranged from 0. 020 5 to 5. 920 8 μg/m L,0. 055 7 to 0. 556 0 μg/m L,0. 064 3 to4. 192 6μg/m L and 3. 862 3 to 151. 273 9μg/m L,respectively. The sensitivity of 9 tested isolates to 4 fungicides differed among isolates,but no significant difference of sensitivity of isolates were found among different areas.
