Abstract:
An extensive survey conducted during 2019-20 and 2020-21 in major mushroom growing farm in districts Jammu, Samba and Udhampur of Jammu division was undertaken to record the status of the disease. The main diseases that occur in mushroom are dry bubble, wet bubble, green mould, and bacterial blotch mainly and the diseases caused by competitor moulds are, white plaster mould, brown plaster mould, false truffle etc. Survey conducted at different mushroom farms of Jammu division revealed maximum incidence of wet bubble disease whereas incidence of brown plaster mould was recorded second highest in Jammu and Samba districts while in case of Udhampur district, white plaster mould was observed second highest to the green mould. In case of mixed infections dry bubble along with green mould was observed higher in Samba and Udhampur. The higher disease incidence in district Jammu could probably be attributed the levels of sanitation adopted and the method of composting was not ideal and also the growers from district Jammu were not so progressive. The onset of pathogen-favourable environmental conditions relating to temperature and high relative humidity outside mushroom production houses seem to promote competitor moulds growth and proliferation in contaminated spent compost, casing materials of button mushroom.
