How much yield loss from ASR can farmers expect?
Risk analyses indicate that ASR could cause yield losses of greater than 10 percent in any United States soybean-growing region. In the southeastern coastal states, losses of up to 50 percent are possible because of more favorable environmental conditions and earlier infection due to the closer proximity to overwintering sources of ASR. Actual losses will depend on weather conditions during the growing season, where the pathogen overwinters, and when the pathogen enters Virginia.
