The response of a commercial strain of Agaricus bisporus (L) Sing to the fungicides famoxadone, tebuconazole and trifloxystrobin was studied in vitro and in vivo. Mycelial growth of A. bisporus on casing medium in tubes was not affected by the reference fungicides carbendazim, prochloraz and mancozeb at 5 mg L −1 and by famoxadone, tebuconazole and trifloxystrobin at 3.27, 0.1 and 1.0 mg L −1, respectively. Overall biological efficiency of mushrooms obtained in pilot-scale cultivation was more affected by single applications of trifloxystrobin than famoxadone. The performance of the latter was comparable to prochloraz or carbendazim. Tebuconazole at 0.8 g m −2 reduced severely total yield and caused pileus deformations. Regarding sporophore whiteness at harvest and after cool storage, carbendazim at 1.2 g m −2 gave better results than prochloraz, famoxadone or trifloxystrobin applied at the same rate. A deviation in sporophore colour at harvest and after cool storage was observed only in the presence of tebuconazole at 1.2 g m −2. Split applications of the fungicides did not favour whiteness retention under cool storage.
