Northern corn leaf blight (NCLB) has been reported in numerous fields in Iowa. Most of the reports have come from central and western Iowa, but since the pathogen that causes this disease is spread by wind and rain, the disease could be more widespread.
We continue to receive several questions about Northern corn leaf blight, Goss’s wilt and fungicides. Here is some additional information.
Basics of fungicides
Parts of rural Iowa are abuzz about fungicide use to manage some emerging diseases, and we have received several questions about the basics of fungicides. A quick reminder, APS PRESS recently published a book geared towards farmers and agronomists on the basics of fungicides.
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.
