Field studies were established in 1996 and 1997 in Atascosa Co. in south Texas to evaluate the response of six peanut cultivars to Rhizoctonia pod rot when sprayed with the fungicides azoxystrobin and tebuconazole. Compared to unsprayed plots, significant disease reduction occurred when cultivars were sprayed with either fungicide. Disease reductions were similar with both fungicides. Tamrun 96 displayed the lowest disease incidence both years with and without a fungicide application. Yields were significantly enhanced both years when either azoxystrobin or tebuconazole was applied to all six cultivars. Tamrun 96 was the highest yielding cultivar in 1996 when sprayed with azoxystrobin and in 1997 when sprayed with tebuconazole. Both fungicides improved grade (TSMK) when compared to the unsprayed checks.
