Fusarium Head Blight Risk Rising in Nebraska: What Growers Need to Know

Jun 09, 2025

By Amanda Easterly and Stephen Wegulo et.al

As Nebraska’s wheat crop enters the critical flowering stage, experts are urging growers — particularly in the Panhandle and western regions — to stay vigilant for signs of Fusarium head blight (FHB), also known as scab.

Dr. Stephen Wegulo, small grains extension plant pathologist at the University of Nebraska–Lincoln, points to recent rainfall events and their timing relative to crop development as major contributors to increased risk.

“Heavy and continuous rainfall before and during flowering poses the highest risk, especially where cereal stubble remains on the soil surface,” Wegulo said.

He recently recommended a fungicide application for a field in Grant following significant precipitation and observed that a nearby trial site was flowering and at heightened risk.

However, Wegulo cautions that fungicide decisions must take economics into account.

Video: Dicamba Returns for Georgia Farmers: What the New EPA Ruling Means for Cotton Growers

After being unavailable in 2024 due to registration issues, dicamba products are returning for Georgia farmers this growing season — but under strict new conditions.

In this report from Tifton, Extension Weed Specialist Stanley Culpepper explains the updated EPA ruling, including new application limits, mandatory training requirements, and the need for a restricted use pesticide license. Among the key changes: a cap of two ½-pound applications per year and the required use of an approved volatility reduction agent with every application.

For Georgia cotton producers, the ruling is significant. According to Taylor Sills with the Georgia Cotton Commission, the vast majority of cotton planted in the state carries the dicamba-tolerant trait — meaning farmers had been paying for technology they couldn’t use.

While environmental groups have expressed concerns over spray drift, Georgia growers have reduced off-target pesticide movement by more than 91% over the past decade. Still, this two-year registration period will come with increased scrutiny, making stewardship and compliance more important than ever.
