Impact of fungicides used for wheat treatment on button mushroom cultivation

Abstract

SUMMARyLittle information is currently available on the potential environmental risks that fungicides applied during wheat cultivation and remaining in straw may have for mushroom production. The substrate for many cultivated mushrooms is mostly based on cereal straw. This review aimed to answer the question whether residues of the fungicides commonly used in wheat production and remaining in straw could be directly or indirectly responsible for changes in yields of Agaricus bisporus. Potential chemical risks of eight fungicides (for wheat treatments) for A. bisporus: mancozeb, carbendazim, thiophanate-methyl, carbendazim+cyproconazole, carbedazim+flusilasole, captan, chlorothalonil and trifloxystrobin are disscused. Only the value of maximum residue level of flusilasole and its formulation was evaluated as higher than medium effective concentration of the fungicide for A. bisporus. As a conclusion, flusilazole treatment could be a limiting factor for using straw for composting and mushroom cultivation.

Characterisation of the interaction of Pseudomonas putida and Pseudomonas tolaasii with Trichoderma aggressivum

“…White button mushroom (Agaricus bisporus (Lange) Imbach) accounts for 15% of total mushroom production worldwide, with a production of 4.43 billion kg in 2013 and it is the most commonly cultivated mushroom in North America and Europe (Royse et al 2017). In mushroom cultivation, naturally occurring bacteria and fungi coexist in the compost, breaking down nutrient rich straw and manure and preparing the substrate for A. bisporus growth (Chang and Miles 2004;Potocnik et al 2012). Minor green mould diseases are caused by several species of the genus Trichoderma which have been present in mushroom industry for many years (Sinden and Hauser 1953;Fletcher and Gaze 2008).…”
