“…These fungicides are applied to casing soil. However, fungicide resistance of the causal agents in button mushroom cultivation has been frequently reported (Berendsen et al, 2010;Medvediev et al, 2019). Apart from this, toxic effects of fungicides on button mushroom (Kosanović et al, 2015) should not be overlooked as well.…”

Button mushroom (Agaricus bisporus) is the predominant mushroom species cultivated around the world. In the button mushroom cultivation, casing soil is one of the main substrate inducing emergence of mushrooms but presence of Trichoderma aggressivum f. aggressivum (causal agent of green mould disease) in casing soil causes devastating yield losses. However, little is known about management of the green mould in button mushroom cultivation. The aim of this study was to examine efficacy of several disinfectants and heat treatments against T. aggressivum f. aggressivum in casing soil and mushroom yield. In this respect, by considering yield (total amount of sporophores) values, in vivo experiments were separately set up according to randomized block design with three replications. As a result, compared to controls, disinfectants [hydrogen peroxide (H202), formaldehyde (CH2O), sodium hypochlorite (NaOCl) and hypochlorous acid (HOCl)] and heat treatments (60, 90 and 120 °C) significantly (P˂0.01) increased mushroom yields up to 18.74 and 24.06% in the treated plots, respectively. Biological efficiency values ranged from 87.16 to 105.72% in the disinfectant treatments, while they varied from 93.15 to 95.68% in the heat treatments. However, applications of the disinfectants at high doses had negative influence on growth of A. bisporus. The overall results suggest that the tested disinfectants and heat treatments may significantly increase button mushroom yield by suppressing development of T. aggressivum f. aggressivum in casing soil. The present study not only reveals management practices that can be used against the green mould in the in vivo but also presents new knowledge for mushroom industry.

“…Repeatedly using the same antifungal agents to control mycopathogens can result in resistant strains or strains with reduced sensitivity. Although prochloraz remains the most effective fungicide to control mushroom diseases, decreased sensitivity of Lecanicillium and Cladobotryum to this chemical has been recorded [1,12,13] . In addition, many chemicals lost approval for use in Europe, for example, chlorothalonil, carbendazim, and benzimidazoles, which have been banned or their use discouraged due to the adverse effects that they may have on the environment [1,14] .…”

This study aimed to determine the possible control of selected pathogenic and competitive fungi of A. bisporus by three nanosilver clay composites and establish the effective concentrations of the composites for inhibiting pathogens. Nanosilver (AgNPs) clay (zeolite, montmorillonite, and palygorskite) composites were synthesized by a microwave‐assisted surface functionalization technique, and various techniques characterized the products. Zeolite and montmorillonite composites showed uniformly distributed spherical AgNPs with an average size of 3.33 nm and 2.85 nm, respectively, whereas palygorskite presented agglomerated and unevenly distributed AgNPs. The influence of the various composites on 9 fungi, including strains of T. aggressivum f. aggressivum, L. fungicola, C. dendroides, and Mycogone sp., was determined in vitro at different concentrations. At 10 mg/mL, AgNP‐zeolite and AgNP‐montmorillonite inhibited 8 out of 9 pathogens, while AgNP‐palygorskite only inhibited 1 pathogen. The nanosilver clay composites tested against A. bisporus revealed no adverse effects on mycelial growth at any concentrations tested. This study confirms that AgNP‐zeolite and AgNP‐montmorillonite composites have effective antifungal properties and can be used as alternative fungicides against mushroom pathogens without affecting A. bisporus growth. However, further investigation is required to unravel the mechanism of selective antifungal activity observed in this study.
