Postemergence Weed Control in Alfalfa May 9, 2018
New alfalfa seedlings do not compete well with weeds and are best managed when small. Here are management tips for when you mow or use chemical control measures.
Residual Herbicides Best Suited to Spring Marestail Management May 2, 2018
Marestail, also called horseweed, is sensitive to most herbicides labeled for its control early in its growth stage, i.e. the rosette stage. Delaying treatment can allow it to compete with corn and soybean, potentially causing significant yield reduction.
Q&A: Which Dicamba Product Should I Use to Kill Broadleaf Cover Crops or Burndown Weeds Before Xtend Soybean? April 27, 2018
With a delayed or compressed planting season, this week several growers asked whether they could immediately plant soybeans after a dicamba application. See how Extension Weed Scientist Amit Jhala replied.
Q&A on Terminating Cereal Rye, Applying a PRE April 25, 2018
A grower asked: My cereal rye cover crop is only 3 to 5 inches tall going into planting season. Can I combine two field operations in one by applying glyphosate to terminate cereal rye and tank-mixing it with a residual herbicide for early season weed control?
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 18, 2018
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.
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%.
