Description

Brown stem rot (BSR) is a common and important soilborne disease of soybean in the North Central U.S. and Canada. BSR can reduce yields over 25%, but losses are typically lower due in part to crop rotation and the use of resistant cultivars. Some have suggested that BSR may be the most undermanaged soybean disease in parts of the North Central Region and it doesn’t get the respect it deserves. Although this could be debated, the fact remains that since BSR was first discovered in Illinois about 70 years ago it has been a persistent yet erratic drag on soybean yields in many areas. The BSR pathogen infects the inner stem and can cause damage to leaves, but symptoms often do not develop on leaves and then BSR may be overlooked in the field.
