Wheat Disease Update
April 7, 2017
Winter wheat growth in Nebraska is progressing at a steady pace, with most fields now green with little or on disease; however, growers are urged to continue scouting their wheat for early signs of disease as current and forecasted wet weather this spring is likely to lead to severe disease outbreaks.
Start Scouting for Wheat Diseases
March 24, 2017
The wheat-growing season is off to an early start due to a mild winter. Wheat fields are looking green from a distance (Figure 1), but closer examination reveals freeze damage in some fields caused by periods of subfreezing temperatures that occurred after growth had resumed (Figures 2 and 3).

Growers Urged to Keep a Watchful Eye for Wheat Viruses This Spring
January 25, 2017
While the mild fall promoted wheat establishment, it also favored survival of wheat curl mites, the leading vector of several viruses common to Nebraska wheat. While much of the state's wheat crop entered winter in very good condition, growers are urged to scout for viruses this spring and assess yield potential of individual fields when making management decisions.

Reports of stripe rust in wheat continued throughout the Panhandle this week, particularly in Kimball and Banner counties. With additional sightings from central and southwest Nebraska, the disease appears to be widespread statewide this fall.
Stripe, Stem, and Leaf Rust in Fall-Planted Wheat
November 11, 2016
Stripe rust, leaf rust, and stem rust have been identified in fall planted wheat in Nebraska, extending into areas where it had previously not developed in the fall. Plant Pathologist Stephen Wegulo looks at the outbreak, conditions contributing to rust development this fall, and the economic and management issues.
Stripe Rust of Wheat Identified in the Panhandle
