摘要： Agaricus bisporus(Lange) Imbach is the most widely cultivated mushroom globally. Wet bubble disease (WBD), mainly caused byMycogone perniciosa, is a major threat toA. bisporusproduction worldwide. In the current study, it was expected to select safe fungicides that can successfully control WBD on mushroom due to the biological similarity ofA. bisporusandM. perniciosa. Thein vitrosensitivity of 24M. perniciosaisolates and fiveA. bisporusisolates to 26 different fungicides were tested. The control efficacies of 13 fungicides against WBD and their effects onA. bisporuswere also determined in the field. The mean EC(50)values of the fungicides onM. perniciosaisolates ranged from 0.0020 to > 100 mu g/ml (P < 0.05). Variation factor values suggested that the fungicides assayed had a narrow range of EC(50)values forM. perniciosa, with the exception of thiabendazole. In addition, fiveA. bisporusisolates exhibited highly variable sensitivities (mean EC(50)0.0275 to > 100 mu g/ml) to these fungicides. Apart from thiophanate-methyl and prochloraz-manganese, hymexazol, trifloxystrobin, fluazinam, fludioxonil, diniconazole, fenbuconazole, imazalil, mancozeb and iminoctadine trialbesilate showed good potential for the control of WBDin vitrosensitivity test. In field trials, prochloraz-manganese and thiabendazole continued to be useful to manage WBD and little effect on mushroom. Fludioxonil, diniconazole, imazalil and fenbuconazole at high doses exhibited better control of WBD and greater yields than other fungicides. And importantly, more rigorous fungicide application and novel cultural strategies are needed for management of WBD with high-qualityA. bisporus.
