Description

Diaporthe/Phomopsis species are pathogens on a wide range of hosts including soybeans (Glycine max L.), and responsible for several diseases, some of which are of economic importance. Under favorable environmental conditions, these diseases can result in in significant yield losses (Backman et al. 1985). For example, yield losses from Stem canker in the Midwest have ranged from minor to in excess of 50% (Hartman et al. 1999). Four Diaporthe species have been reported pathogenic on soybean – Diaporthe sojae, the causal agent of pod and stem blight; Diaporthe caulivora and Diaporthe aspalathi, causal agents of Northern and Southern stem cankers, respectively; and Diaporthe longicolla, causing seed decay (Hartman et al. 1999).
