Thirteen isolates of Cladobotryum spp., isolated from diseased fruiting bodies of Agaricus bisporus, sampled from mushroom farms in Serbia during 2003-2006, were studied. Sensitivity to several selected fungicides was tested and all isolates were found to be highly sensitive to iprodione (EC50=0.35-2.30 mg/L), benomyl (EC50=0.14-0.97 mg/L) and especially to prochloraz-Mn (EC50=0.02-0.09 mg/L). The minimum inhibitory concentration (MIC) of benomyl was 4 mg/L, while those of prochloraz-Mn and iprodione exceeded 1000 mg/L. The minimum fungicide concentration (MFC) of benomyl was 4 mg/L, and none of the tested concentrations of prochloraz-Mn and iprodione were lethal to any of the investigated Cladobotryum spp. isolates.
