Abstract

The severity of Sclerotinia sclerotiorum as detected on aerial infrared photography was correlated with actual yield losses in the field. Peanut pod losses in the soil increased as disease severity became more pronounced as determined by imagery interpretation. In areas of fields on the imagery interpreted to be slightly, moderately and severely infected with S. sclerotiorum, pod losses due to infection were 2, 5 and 7 times greater, respectively, than normally expected losses in nondiseased areas (ca. 300 kg/ha). Sclerotial populations were 10 times greater in soil from severely infested areas on the field than from slightly and noninfested areas.
