Phaseolus dry beans are the leading grain legume crop with an annual world production of 20 million metric tons (mmt) and the U.S. is the leading export nation marketing 40% (0.4 mmt) of all dry bean production overseas. Dry or dry edible beans (DEB) are produced in the U.S. on 1.7 million acres by nearly 11,000 farms with estimated sales at $1.8 billion. Production occurs in fourteen states and includes fifteen different varieties of beans. However, dry bean diseases can dramatically reduce yield, quality of harvested beans and therefore, greatly affect grower profits. White mold in particular is a key pest of dry beans in Michigan. Serious losses can occur when weather conditions are favorable for disease development and disease organisms are present. Except for the driest seasons, 100% of crop acres are at risk and up to 40-50% can be affected, with yield losses as high as 50% occurring within 2 weeks late in the growing season.
