ABSTRACT

Since the use od phenolic disinfectants for impregnating and disinfecting of wood in mushroom- -growing cellars was banned in Poland for ecologic and hygienic reasons, the new product, namely Mycetox, containing quaternary ammonium compound and boric ad d has been registered for this purpose. Mycetox belongs to new generation products and is non toxic for man and the environment. It is first Polish product developed for the genera] disinfection as well as for impregnating purposes in mushroom farms. The efficacy of Mycetox in mushroom-growing cellars has been evaluated basing on its fungicida] properties in the different substrates used for the cultivation of mushrooms. Also its influence on mushroom spawn growth, crop yield, and the penetration of spawn into wooden cages impregnated with Mycetox as well as its influence on blanching of mushrooms has been investigated.
