Wheat Disease Update for Central to Western Nebraska
June 22, 2018
Wheat diseases were found at varying levels across a wide area of fields surveyed this week in western Nebraska in conjunction with the 2018 Wheat Tours.
Wheat Update: Diseases Increasing
June 13, 2018
Recent rains have created favorable conditions for disease development in wheat. If irrigating, manage applications to reduce further development and spread of diseases.
Wheat Diseases Minimal
June 8, 2018
Diseases continue to be absent or at very low levels in Nebraska wheat, with no reports of stripe rust or leaf rust and low levels of powdery mildew. Prevailing high temperatures and dry conditions in many areas have reduced the risk of significant disease development.
Wheat Disease Update — Levels Still Low
May 31, 2018
Wheat fields in southeast and south central Nebraska were green with little disease and high yield potential, based on this week's field survey. Recent rains relieved moisture stress in wheat in some areas of the state, but more rain is needed in southeast Nebraska to alleviate stress.
Wheat Disease Update: Southeast Nebraska
May 24, 2018
A survey of wheat in southeast Nebraska found diseases generally absent or at very low levels, mainly due to recent dry conditions. Continued scouting for foliar diseases is recommended, especially in areas that receive rainfall and where the wheat crop has not yet headed.
Wheat Disease Update
May 18, 2018
A survey of wheat fields in central, southwest, and Panhandle regions of Nebraska found little disease. In addition recent rains have helped alleviate moisture stress.
Addendum to May 11 Wheat Disease Update
May 14, 2018
To differentiate sulfur deficiency from nitrogen deficiency in wheat, look for field patterns. Symptoms of yellowing limited to certain areas is more typical of sulfur deficiency. In addition, symptoms of sulfur deficiency are more conspicuous when soil temperatures are cold as in early spring.
Wheat Disease Update
May 11, 2018
No diseases were found during a survey of wheat fields in south central and southeast Nebraska this week, but growers are urged to continue scouting as recent rains may create conditions favorable to disease development.
