Timing of Cover Crop Termination and Related Factors
April 20, 2018
Should the cold spring delay cover crop termination? Growers walk a fine line between growing cover crops long enough to get the biomass they want without reducing yield in the following grain crop. This discussion from an agronomist, entomologist and weed scientist looks at various factors to consider.
How Temperature and Rain Can Affect Burndown Herbicides
April 3, 2020
Finding a good time for burndown herbicide applications has been a little tricky this spring, given the below-normal temperatures the first half of April and intermittent snow and rain, all of which can decrease herbicide efficacy. Checking the forecast can help identify an optimal window for application.
Dicamba Off-target Injury Issues in Nebraska Soybean
January 8, 2018
To avoid some of the off-target dicamba injury that occurred in 2017, new label requirements and application recommendations are being made for 2018. This is an article from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics.
Market Journal on Importance of Following Dicamba Labels
April 6, 2018
This week on Market Journal Greg Kruger, Nebraska extension weed science and application technology specialist, discusses the importance of reading, studying, and following dicamba product labels.
University Research: Ragweed Can Pose a Serious Threat to Soybean Yield
March 30, 2018
Once thought to be an innocent bystander to field crop production, common ragweed can "drastically reduce soybean yields," according to University of Nebraska-Lincoln research. In dense populations, the loss was shown to be 40-76%.
Pre-emergence Residual Herbicides are the Foundation of Soybean Weed Control
March 29, 2018
Even with new dicamba-resistant soybeans, pre-emergence, residual herbicides are needed to mitigate yield loss due to weed competition, provide a longer time for soybean to establish, and reduce selection pressure for weeds resistant to post-emergence herbicides.
Sulphur Cinquefoil — An Invasive Species in Nebraska
March 16, 2018
Sulphur cinquefoil is a perennial forb and aggressive invasive species that establishes quickly in disturbed areas and over-grazed sites. Prevention and, if necessary, timely identification and management are the best routes to containing this invader.
Controlling Weeds in and Fertilizing Winter Wheat, Particularly Late-Seeded Fields
March 15, 2018
With many wheat fields planted later than normal due to rain, stands are not as competitive with weeds and younger plants may be susceptible to herbicide injury, making a good weed management plan even more important this year.
