 ABSTRACT

Banded leaf and sheath blight of maize is caused by a destructive and versatile pathogen Rhizoctonia solani f. sp. sasakii. To assess the occurrence of banded leaf and sheath blight (BLSB) of maize in Himachal Pradesh, an extensive survey was conducted during the month of August, 2013 in five districts of Himachal Pradesh viz., Kangra, Mandi, Hamirpur, Una and Bilaspur to record the incidence and severity index of the disease. The disease occurred throughout the state with maximum incidence of 58.8 % at Bilaspur followed by Una (52.8 %), Kangra (38.4 %), Mandi (34.3%) and Hamirpur (30.0 %) with average severity index of 61.0, 66.5, 45.9, 41.3 and 42.2 % respectively. The cultural and sclerotial characteristics of different isolates collected from different locations were recorded.

Key words: Banded leaf and Sheath blight (BLSB), Incidence, Maize, Severity index and Survey
