Abstract

Abstract: 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.

Key words: Sclerotinia sclerotiorum, chemical fungicides, toxicity, controlling effect
