Abstract
Epidemics of Alternaria blight (Alternaria helianthi (Hansf.) Tubaki and Nishihara: A. alternata (Fr.) Keissler) simulated at different plant growth stages showed yield losses as high as 57 and 48 percent in "Morden" and "APSH11" varieties of sunflower respectively. Other yield attributes like test weight of seed and number of seeds per head were also significantly reduced. Regression equations developed on percent disease severity and yield losses gave a coefficient of determination between 0.88 and 0.96.
Keywords: Sunflower, blight, Alternaria helianthi, Alternaria alternata, yield.
