Maize (Zea mays L.) is an important food and feed crop which ranks third after wheat and rice in India and in the world. It is cultivated under diverse environmental conditions. It is affected by more than 60 diseases, among them foliar disease, turcicum leaf blight is one of the important disease causing moderate to severe losses in yield. Hence, to know its damage and the extent of severity, a survey was carried out in seven major maize growing districts of southern Karnataka. The highest disease index was noticed in Chickmagalur district, which is having a mean PDI of 55.07 succeeded by Hassan and Chitradurga district with a mean PDI of 51.2 and 48 respectively. However, the least per cent disease index was recorded in Mysore (42.4) followed by Kodagu district with a PDI of 44.5.
