Fall Weed Control Options for Winter Wheat
August 31, 2016
Weed management is a long-term battle that needs to continue even in tight margin years.Although herbicide costs may seem prohibitive, it’s important to consider the long-term implications of limiting or eliminating the use of herbicides in crop production systems.Weeds left unmanaged after wheat harvest use valuable nutrients and water needed for the following year’s crop while producing seeds to replenish the soil seed bank.
New Herbicides & Managing Multiple Herbicide-Tolerant Crops
July 28, 2016
In Nebraska, eight weed species (common ragweed, common waterhemp, giant ragweed, kochia, marestail, Palmer amaranth, redroot pigweed, and shattercane) have been confirmed resistant to at least one herbicide. Six of them — common ragweed, common waterhemp, giant ragweed, kochia, marestail, and Palmer amaranth — have been confirmed resistant to glyphosate in Nebraska. This article reviews information presented at the Weed Management Field Day at the UNL South Central Ag Lab, focusing on field demonstrations and methods to reduce the development of further herbicide resistance.

Post-Harvest Weed Control in Winter Wheat
June 29, 2016
Timely control of weeds following winter wheat harvest can limit soil moisture loss to weeds and prevent the deposit of more weed seeds in the soil, two factors that can benefit the next crop's yield. In addition, timely control of volunteer wheat is essential in reducing the spread of wheat streak mosaic disease. See what influences effectiveness of weed control and how to make your crop more competitive.
Control Volunteer Winter Wheat and Other Weeds Now to Increase and Protect 2017 Yields, Income

By far, the greatest risk of losses from mite-vectored viruses occurs when there is a summer "green bridge" of volunteer wheat emerging before harvest. This almost always occurs as a result of wheat seed head shatter from hail storms (Figure 1).
Herbicide Injury and Pathogen Infection on Soybean Seedlings
