Influence of Planting Date and Cultivar on Soybean Sudden Death Syndrome in Kentucky

Abstract

In a 3-yr study in western Kentucky, soybean (Glycine max) cultivars differed in susceptibility to soybean sudden death syndrome (SDS), and their reactions, while not always consistent, were affected by planting date. In 1987 and 1988, May plantings resulted in higher SDS levels for most cultivars than did plantings in mid-June through early July. The reverse occurred for some cultivars in 1986, and others were unaffected by planting date. While the relative SDS reactions of most cultivars were generally consistent among years, all cultivars were affected, at least moderately, in one or more plantings (...)
