Advances in Understanding the Management of the Wheat Stem Sawfly
January 28, 2020
Over the past few decades, WSS populations have greatly increased and expanded in the Nebraska Panhandle, becoming the most economically significant pest of wheat.
Management Decisions Impact Wheat Stem Sawfly Populations
August 30, 2019
University research in the Nebraska Panhandle suggests that changing two management strategies may help significantly reduce wheat stem sawfly pressure in winter wheat. Over the years, the sawfly has become a major pest in wheat with few known control measures.
Some Fields Doing Better Than Expected Without Irrigation, Some Not

Time-lapse videos and photos capture the status of crops affected by the loss of irrigation water to growers in the North Platte River Valley in eastern Wyoming and western Nebraska.
Why Control of Volunteer Wheat is Critical to Protecting 2020 Yields
July 12, 2019
Volunteer wheat can create a "green bridge," providing a route for mites to move to and infest emerging wheat. These mites can then transmit wheat streak mosaic virus, High Plains virus, and Triticum mosaic virus, or all of them to create a complex of infections.
Using Degree-Day Models to Predict Western Bean Cutworm Flights
June 21, 2019
With late planting, slow emergence, and cooler summer temperatures affecting corn development, will corn be spared from western bean cutworm damage in 2019. Unfortunately, models indicate WBC growth is also delayed. See a table of predicted dates for 2019 WBC flights in Nebraska and surrounding states.
