Mushrooms are affected by a large number of biotic and abiotic agentsdirectly or indirectly.
Fungal pathogens like Mycogene perniciosa, Lecanicillium fungicola, Cladobotryum causes
Dry bubble, Wet bubbleand Cob web disease in mushroom respectively. Trichoderma is the
other species responsible for green mould (T.aggressivm in button mushroom, T.pleurotum in
oyster mushroom & T.harzianum in shitake mushroom). Pseudomonas tolaasii is the
bacterium that is responsible for causing Bacterial brawn blotch disease in Mushroom. The
activities of these microbes against mushroom are controlled by usingchemical fungicides
that includesBitertanol, Captan, Carbendazium, Hexaconazole and Mancozeb. Unfortunately,
the usage of these fungicidescauses negative impact on human health and environment. The
aim of our study is to utilize the natural plant extracts as an antifungal for treating the fungal
pathogens affecting mushroom. It is observed that these extracts used exhibit the maximum
activity in controlling the pathogens.
