Abstract
Twenty isolates of Verticillium fungicola var. fungicola collected from diseased fruit-bodies of Agaricus bisporus from prochloraz-treated crops, were exposed to a range of concentrations of six chemicals (benomyl, chlorothalonil, formaldehyde, iprodione, prochloraz-Mn-complex and prochloraz + carbendazim) in vitro. EC50 values were determined for each fungus-fungicide combination. All isolates were more sensitive to prochloraz-Mn-complex (EC50 values less than 5 mg 1−1) than to the remainder fungicides, and only seven isolates were moderately sensitive (EC50 values between 5 and 50 mg 1−1) to prochloraz + carbendazim. All isolates were moderately sensitive to formaldehyde, whereas the majority of isolates were very resistant to the other three fungicides (benomyl, chlorothalonil and iprodione).
