Diseases of White Button Mushroom (Agaricus bisporus)- A Potential Threat to Mushroom Industry

Mushrooms have been used by humans for millennia. The commonly cultivated mushrooms include Agaricus, Lentinus, Flammulina, Pleurotusand Volvariella. In India, Button mushroom (Agaricusbisporus)is the most followed Pleurotus(Shah et al., 2013). Mushrooms are mainly subjected to bacterial, fungal and viral diseases. production of fruiting bodies is severely afflicted fungal, bacterial pathogens that can cause diseases which an effect on yield quality (Potocnik 2008). Improper pasteurization compost casing soil be major source Once disease introduced in farm it carried out different agencies like air, water, machines workers (Munshi 2010). Fungal occurring white button dry bubble (Verticillium spp.), cobweb (Cladobotryumspp.), green mould (Trichoderma harzianum) viride). Over past two decades, caused T. aggressivum has serious mushroom. Among diseases, blotch (Pseudomonas tolaasii) common mushrooms. Dieback various virus strains (Gupta 2018). These a threat industries worth millions as losses due these may go up 100%. Depending upon stage severity infection, prevailing environmental conditions, often complete crop failure Considerable cultivation process occur lower productivity, decrease shortened shelf-life. Moreover, with its rapidity cropping makes suitable environment augmentation pathogen inoculum thus control more difficult (Todorovic 2012).
