Other than lack of water, diseases are the number one yield-limiting factor of peanut, Arachis hypogaea L. Recently released peanut cultivars, ‘C-99R', ‘Georgia-01R', ‘DP-1', and ‘Tifrunner', with significantly improved levels of resistance to leaf spots (Cercosporidium personatum and Cercospora arachidicola), southern stem rot (Sclerotium rolfsii), and spotted wilt disease (caused by tomato spotted wilt tospovirus), were evaluated for response to a reduced fungicide application program. The standard of eight fungicide applications was compared to four fungicide applications. Trials were conducted in crop years 2003 and 2004 on the University of Georgia's Ponder Farm. Within each cultivar, there was no difference (p<0.05) in percent southern stem rot when sprayed four or eight times with fungicide. Tifrunner had significantly higher southern stem rot, 41%, than the other cultivars (9-16% range). In 2003, spotted wilt disease was significantly higher averaged across all four cultivars when sprayed only four times compared to eight fungicide applications. Leaf spot ratings were not significantly different on all cultivars when fungicides were applied four or eight times.
