Banded blight - a new record on finger millet in Karnataka.


Finger millet is important small millet in Southern Karnataka. The banded leaf blight caused by Rhizoctonia solani was for the first time seen in a farm at Narasapura village in Kolar district, Karnataka during kharif 2006. The disease appeared as oval to irregular, light t6 dark lesions on the lower leaf sheath. Later central portion of lesions turned white to straw with narrow, reddish brown border. Regularly distributed such spots were also seen on leaf blades. On peduncles, fingers and glumes irregular to oval, dark brown to purplish necrotic lesions are formed. The pathogen isolated from different diseased parts of the plant yielded Rhizoctonia solani.
