Goss's bacterial wilt and leaf blight of corn—prevalent in the U.S. corn belt during the 1970s and ‘80s—has re-emerged in susceptible corn hybrids in past decade with confirmed infections from Texas to Manitoba.
Providing information about the resurgent disease is a new educational presentation from the Plant Management Network (PMN) entitled "Goss's Bacterial Wilt and Leaf Blight of Corn," now available as part of the Focus on Corn resource for producers, consultants, and extension agents.
The webcast, developed by Tamra Jackson-Ziems, Plant Pathologist at the University of Nebraska–Lincoln Extension, provides information about the disease’s ability to over-winter in field residue and infect plants through wounds and natural openings.
The presentation discusses the cropping practices and environmental factors that have the greatest affect on the development of Goss's wilt and provides information about how to:
- Identify common symptoms during plant maturation
- Accurately diagnose infections using a combination of tests
- Avoid infections using resistant hybrids and crop rotations
- Reduce severity through tillage, weed control, and chemical interventions
The 30-minute presentation will remain open access through June 30 in the Focus on Corn webcast resource.
