A survey of in vitro sensitivity of 13 isolates of the mushroom pathogen Cladobotryum
spp. to the fungicides thiophanate-methyl, carbendazim, cyproconazole+carbendazim and
flusilazole+carbendazim was undertaken. The isolates were collected from diseased fruiting
bodies of Agaricus bisporus sampled from mushroom farms in Serbia over the period
2003-2006. Sensitivity to the selected fungicides was tested and all isolates were found to
be highly sensitive to carbendazim (EC50 = 0.24 - 2.92 mg l-1), cyproconazole+carbendazim
(EC50 = 0.33 - 1.82 mg l-1) and especially to flusilazole+carbendazim (EC50 = 0.02 - 0.11 mg
l-1). All the isolates tested were weakly resistant to thiophanate-methyl and had EC50 values
in the region of 6.53 to 12.09 mg l-1. Iz obolelih plodonosnih tela Agaricus bisporus prikupljenih u gajilištima šampinjona u
Srbiji tokom 2003-2006. dobijeno je trinaest izolata Cladobotryum spp. Ispitana je njihova
osetljivost na fungicide tiofanat-metil, karbendazim, ciprokonazol+karbendazim i
flusilazol+karbendazim in vitro. Ispitivanje osetljivosti izolata na fungicide je pokazalo da su
svi izolati visoko osetljivi na karbendazim (EC50=0,24-2,92 mg l-1), ciprokonazol+karbendazim
(EC50=0,33-1,82 mg l-1) i naročito na flusilazol+karbendazim (EC50=0,02-0,11 mg l-1). Svi testirani
Cladobotryum spp. izolati su bili umereno rezistentni na tiofanat-metil sa EC50 vrednostima
u rasponu od 6,53 do 12,09 mg l-1.
