Scouting Advised for Alfalfa Weevil
May 6, 2020
Alfalfa weevils have been reported damaging alfalfa in north central Kansas. As temperatures warm up, expect to see alfalfa weevil larvae in southern Nebraska and slightly later, in northern Nebraska.
Army Cutworm Scouting Urged in Western Nebraska Wheat and Alfalfa
March 27, 2020
Army cutworms have been spotted in Kansas and Nebraska crop fields this month. This is an important time to scout for this pest, particularly in wheat and alfalfa.
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.
Novel Strategies for the Management of the Western Bean Cutworm
January 22, 2020
The western bean cutworm is a pest of corn and dry bean. Typically, control is achieved by pyrethroids or transgenic traits. However, control with pyrethroids may prove difficult and transgenic traits are not available for dry bean. Biological control may prove to be a useful tool for growers of both crops.
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
August 23, 2019
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 It's So Important to Control Volunteer Wheat and Weeds in Wheat Stubble After Harvest
June 22, 2023
Volunteer wheat can provide the summer "green bridge" for the disease wheat streak mosaic and other virus diseases, as well as soil water loss that could translate into a substantial decrease in yields the following year.
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.
