Abstract
Dry bubble disease induced by Verticillium fungicola has been observed as an important disease of white button mushroom (Agaricus bisporus) in India. The symptoms produced on differentiated fruit body are localized light brown depressed spots. The adjacent spots coalesce together and form irregular blotches. If the pathogen infection is established before differentiation, sclerodermoid fruiting bodies appear on casing surface. Five plant extracts tested by poisoned food technique inhibited the growth of both host and pathogen. But their cumulative effect was found to improve the mushroom yield. Azadirachta indica (Neem) effectively controlled the pathogen and increased the yield of white button mushroom by 16.52% compared to control. Key words: Agaricus bisporus, Verticillium fungicola, dry bubble, wheat straw compost, compost, long method of composting, short method of composting, Azadirachta indica, Parthenium parthefolium.

Haryana has become one of the leading states in white button mushroom production with 5312 tons/annum (Tiwari, 2004). The most common fungal diseases of white button mushroom are cobweb, dry/wet bubble, false truffle and green mould (Sharma, 1995). Dry bubble caused by Verticillium fungicola is prevalent in all mushroom growing areas and has 25-50% incidence (Sharma, 1995).
