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-1), benomyl (EC50 = 0.14-0.97 mg L-1) and
especially to prochloraz-Mn (EC50 = 0.02-0.09 mg L-1). The minimum inhibitory concentration
(MIC) of benomyl was 4 mg L-1, while those of prochloraz-Mn and iprodione exceeded
1000 mg L-1. The minimum fungicide concentration (MFC) of benomyl was 4 mg L-1, and
none of the tested concentrations of prochloraz-Mn and iprodione were lethal to any of the
investigated Cladobotryum spp. isolates. Trinaest izolata Cladobotryum spp., dobijeno je iz obolelih plodonosnih tela Agaricus bisporus
iz gajilišta šampinjona u Srbiji tokom 2003-2006. godine. Ispitivanje osetljivosti izolata
na fungicide je pokazalo da su svi izolati visoko osetljivi na benomil (EC50 = 0.14-0.97
mg L-1), iprodion (EC50 = 0.35-2.30 mg L-1) i naročito na prohloraz (EC50 = 0.02-0.09 mg L-1).
Minimalna inhibitorna koncentracija (MIC) benomila je bila 4 mg L-1, a prohloraza i iprodiona
veća od 1000 mg L-1. Minimalna fungicidna koncentracija (MFC) benomila je takođe bila
4 mg L-1, a nijedna od testiranih koncentracija prohloraza i iprodiona nije bila letalna za
Cladobotryum spp. izolate.
