Isolation and identification of Mycogone perniciosa,
causing wet bubble disease in Agaricus bisporus
cultivation in Kashmir
Button mushroom is an important edible fungus cultivated in
Kashmir, but it is often attacked by disease causing
organisms, including fungi, bacteria and viruses. Some of
them cause huge losses by reducing the yield significantly
or result in serious crop failures, depending upon the
severity and stage of appearance. One of the mycoparasite,
Mycogone perniciosa, the cause of wet bubble disease,
was observed in samples collected from mushroom farms of
three districts: Srinagar, Budgam and Pulwama of Kashmir
Valley. This fungal pathogen was constantly associated with
the disease and produced typical and characteristic symptoms
of wet bubble disease. Isolation of the pathogen was made
from diseased fruiting bodies. The pathogenicity proved in
accordance with the Koch’s postulates both in vivo as
well as in vitro. The pathogen was found to attack
button mushroom at all the growth stages but the immature
mushroom were found more susceptible than the mature ones,
and characteristic symptoms developed on all the inoculated
sporophores. The mushrooms were malformed with swollen
stipes and with deformed caps. The in vitro
interaction between Agaricus bisporus and M.
perniciosa mycelia indicated the hyphal collapse of the
former at the point of contact between the two fungi. There
was no zone of inhibition, found in this interaction.
Key words:
Yield, symptoms, susceptible, sporophores, interaction,
hyphal collapse.
