摘要：Collar rot of tuberose caused by Sclerotium rolfsii causing heavy damage to the cropwas recorded in Odisah.The disease as characterised by the appearance of chlorotic rotting patches and white mycelia masses on the leaves, followed by drooping and drying..To study about this disease, with a chain of operations like planting material collection, isolation of pathogens, sterilisation of glassware, preparation of different media and inoculation in the media were conducted. The highest incidence /mortality of tuberose plants was observed when 12.5-15g. Of inoculums were used.Test conducted in vitro suggested that clayey soul was most favourable for stem rot infection in tuberose plant.Incidence of the disease ws very low in sandy soil indicating its unsuitability for sclerotium rolfsii to cause collar rot.
