Abstract
Gray leaf spot, caused by the fungus Pyricularia grisea, was reported in the early 1970s to be a damaging disease of annual ryegrass grown for forage in the southeastern United States. Forage yield losses were so severe that the disease was named ryegrass blast.
This NebFact discusses the diagnosis, future occurrences, and management of gray leaf spot in Nebraska and surrounding states.
