Abstract
A roving survey was carried out for peduncle blight and anthracnose of tuberose caused by Lasiodiplodia theobromae and Colletotrichum gloeosporioides respectively, in major affected areas of northern Karnataka. From the results obtained, it was clear that, vegetative state is more vulnerable to the attack of the pathogens then flowering stage irrespective of the locations. Red soil type recorded higher disease severity as compared to black soil. Among the surveyed areas, the severity of peduncle blight of tuberose was maximum in Tumminakatti village (45.33%) of Haveri district while anthracnose severity was maximum in Saidapur farm (31.11%) of Dharwad district. Least disease severity of peduncle blight and anthracnose was recorded in Chandanamatti (13.33%) and Nigadi (6.67%) villages of Dharwad taluk of Dharwad district respectively.
