Abstract:
Maize is considered to be the third most important cereal after rice and wheat in India. It is being cultivated worldwide in a wider range of environmental conditions, due to its greater adaptability. It is known to be affected by more than 62 diseases. Among them, turcicum leaf blight caused by Exserohilum turcicum (Pass.) Leonard and Suggs is of significant importance as it drastically reduces the yield by reducing photosynthetic activity of the plant. Hence, in order to know the disease occurrence and extent of its severity, an extensive roving survey was conducted in Shivamogga and Davanagere districts. The highest percent disease index (PDI) was recorded in Honnali taluk of Davanagere district (61.28) as against least in Soraba taluk of Shivamogga district (18.55).
