摘 要：
为了筛选适合江西省油菜菌核病菌(Sclerotinia sclerotiorum)防治的杀菌剂,采用菌落直径法和大田常规喷雾法,分别研究了8种化学杀菌剂对油菜菌核病菌的室内毒力及田间防治效果。结果表明,菌核病菌对戊唑醇、咪鲜胺、氟啶胺、多菌灵、啶酰菌胺、腐霉利和吡唑醚菌酯均表现出高度敏感,EC50在0.005～0.174μg/mL,对代森锰锌不敏感。田间防治效果表明,腐霉利、多菌灵、戊唑醇和吡唑醚菌酯的效果较好,防治效果分别为86.44%、82.48%、81.35%和77.40%。

摘 要：
In order to select suitable fungicides for the control of rape sclerotinia stem rot(Sclerotinia sclerotiorum) in Jiangxi province, the toxicity of 8 fungicides on Sclerotinia sclerotiorium was tested in laboratory by colony diameter law, and the experiment of controlling effect was carried out in field by conventional spray. The results showed that the Sclerotinia sclerotiorium was highly sensitive to tebuconazole, pochloraz, fluazinam, carbendazim, boscalid, procymidone and pyraclostrobin, EC50 of which were between 0.005 μg/mL and 0.174 μg/mL, but insensitive to mancozeb. Procymidone, carbendazim,tebuconazole,pyraclostrobin showed better controlling effect in field, with efficacy of 86.44%, 82.48%, 81.35% and 77.40%, respectively.
