In vitro toxicity of fungicides of different mode of action to Agarics Bosporus (Lange) imbach

Isolates of Agarics Bosporus strains F56 and U3 were tested for sensitivity to several selected fungicides in vitro. The analysis showed that flusilasole + carbendazim and cyproconazole + carbendazim were the most toxic fungicides to A. bisporus strain F56 with respective EC50 values of 0.04 and 0.23 mg/l. The least toxic fungicides were carbendazim (EC50 = 16.58 mg/l) and trifloxystrobin (EC50 = 20.69 mg/l) to A. Bosporus F56 and binomial (EC50 = 14.99 mg/l) to A. Bosporus U3.
