The pathogen is a serious concern to soybean farmers and can cause detrimental yield loss during the growing season. Since 2000, the fungus has been present in the northern and southern U.S. states as well as 27 other countries spanning North and South America, Europe Africa and Asia (Lin and Kelly 2018). The fungus is very prevalent in the southern U.S., but in previous years it has spread to northern soybean fields (Smith, 2020). During a wet season, the fungus can cause up to a 30% loss of soybean crop in some fields (Bayer, 2018). Other authors note a yield loss as high as 60% due to the reduction in photosynthetic area, early leaf loss and reduced seed quality (Lin and Kelly, 2018).
