Oats Crown Rust Inoculum Abundant This Year

Crown rust is the most important fungal disease of oats in South Dakota. In years with heavy disease pressure, susceptible cultivars can have over 80% yield loss due to crown rust. The presence of crown rust inoculum on buckthorns can be an indication of the likely risk for crown rust to develop during the growing season. Buckthorns scouted recently were loaded with crown rust inoculum.
