ABSTRACT

Four isolates of Mycogone perniciosa, separated from diseased culinary-medicinal button mushroom Agaricus bisporus fruiting bodies collected in mushroom farms in Serbia, were studied. The isolates were identified by observing their colony morphology and pathogenic characteristics. Peat/lime casing was the primary source of infection. A sensitivity test for the selected fungicides has shown that all isolates were highly sensitive to iprodione (EC50 = 3.10−4.08 mg L−1), benomyl (EC50 = 0.28−0.46 mg L−1), and, especially, prochloraz-Mn (EC50 = 0,0002−0,008 mg L−1). The minimum inhibitory concentration of prochloraz-Mn was 5 mg L−1, benomyl 10 mg L−1, and iprodione was higher than 1000 mg L−1. The same benomyl concentration had a fungicidal effect, whereas none of the tested iprodione and prochloraz-Mn concentrations were fungicidal for the M. perniciosa isolates. Among seven essential oils, Thymus vulgaris oil possessed the highest antifungal activity against the studied mycopathogen, with a minimum inhibitory concentration and minimum fungicidal concentration of 0.02 μL mL−1 of air. Pistacia terebinthus essential oil demonstrated the lowest antifungal effect, with minimum inhibitory and minimum fungicidal concentrations of 0.16 and 0.65 μL mL−1 of air, respectively.
