A field experiment was carried out in deep black soil at Main Agricultural Research Station, College of Agriculture, University of Agricultural Sciences, Dharwad, Karnataka during kharif 2010, under rain-fed condition. The yield losses due to common rust were found directly related to disease severity. The avoidable yield losses due to disease were in the range of 11.75 to 60.53% in different spray schedule. Crop loss assessment at different fungicide spray schedule revealed that there was significant reduction in yield when disease severity was more than 50%. Six sprays of the Hexaconazole at 0.1% completely controlled the disease and contributed to increased yield.
Key words: Maize, common rust, Puccinia sorghi, yield loss.
