Researchers at the University of Illinois have cooperated with field scouts and visually examined many hundreds to thousands of specimens in annual surveys for the past several years, and we have evaluated numerous soybean lines/cultivars for pathogen resistance. Recently, they have developed quantitative, DNA-based molecular assays for the soy pathogens causing charcoal rot, sudden death syndrome, Phytophthora root and stem rot, anthracnose, and Phomopsis seed decay. Other laboratories have developed similar assays for the soy pathogens causing brown stem rot, frog eye leaf spot, Rhizoctonia root rot, and soybean cyst nematode, rust, and possible others. We have used some of these as well....
