Abstract

Diaporthe phaseolorum var. caulivora is a fungus that can infect soybeans (Glycine max) and cause development of stem cankers that usually result in girdling of stems and death of plants. Stem canker disease of soybean was first described by Welch and Gilman (11) when they differentiated the stem canker fungus from D. phaseolorum var. sojae, which causes pod and stem blight of soybean. Welch and Gilman first identified the causal organism of stem canker as D. phaseolorum var. batatatis, a fungus described by Harter and Field (6) as being pathogenic on sweet potato. Athow and Caldwell (1) revised the variety name to the one in current use because of differences in morphology and pathogenicity between cultures of D. phaseolorum var. batatatis, known to be pathogenic on sweet potato, and the stem canker fungus.
