To help farmers and agronomists identify, scout, and manage corn diseases a new Corn Diseases booklet, published by Iowa State University Extension and Outreach, is now available to crop producers and industry professionals. The up-to-date publication provides current recommendations for management, along with identification and scouting information. Also included are illustrated disease cycles for primary diseases, a foliar disease estimation chart, and corn growth and development and staging information.
