TAR SPOT RATINGS
Something went wrong. Please try again later...
First discovered in the United States in 2015, tar spot (Phyllachora maydisis) is a fungal disease of increasing agronomic importance in corn. As of 2021, it has been confirmed in an expanding swath of counties in the central and eastern Corn Belt. Fortunately, some hybrids show more tolerance to the disease than others. Corteva Agriscience researchers recently developed a rating scale that accurately rates tolerance levels for Brevant® brand products.
