Researchers are working to learn more about a little-known corn disease that has surfaced in nine states across the U.S. this summer. DTN reports the disease is known for now as bacterial leaf streak blight, which originated in South Africa. Colorado State University says there is limited information about the disease and its impacts on corn production. It’s possible the disease entered the U.S. two years ago, as researchers say the lack of information led to a delay in confirming the disease. Currently, researchers have no recommendations for farmers regarding management. Bacterial leaf streak has surfaced in field corn, seed corn, popcorn and sweet corn. Researchers say the disease has been confirmed in Colorado, Iowa, Illinois, Kansas, Minnesota, Nebraska, Oklahoma, South Dakota and Texas.
