Charcoal rot of soybean is caused by the soilborne fungus Macrophomina phaseolina, which can infect over 500 agricultural crop and weed species. This disease has recently emerged as a threat to soybean in the North Central region of the U.S. and Ontario, Canada, where warmer summer and winter temperatures and reduced rainfall have likely contributed to its prevalence.
Growers in the North Central region of the United States—especially Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, and Wisconsin—will find management practices that will help them manage charcoal rot in their soybeans using resistant varieties and certain cultural practices (8 pages; 2014).Download
