Several post-emergence herbicides are available for control of marestail where spring weather may have interfered with application or efficacy of early spring burndown and/or pre-emergence herbicide applications.
On-site demonstrations of herbicides for weed control in corn, popcorn, and soybean and a study on terminating cereal rye before and after planting soybean are among those to be featured at the university's South Central Agricultural Laboratory near Clay Center.
A new dicamba-based herbicide, Tavium, has been approved for use in Roundup Ready 2 Xtend soybean (dicamba/glyphosate-resistant soybean). Like the other dicamba-based soybean herbicides, it requires special training before it can be used.
With flood, cold, and wet conditions in March/April, many producers are facing a smaller than expected window for making their burndown herbicide applications and should carefully consider required planting intervals when selecting which product to use in which crop.
"If I had RUP dicamba training in 2018, do I need training in 2019?" The answer to that question, which is "Yes," and other questions about training and new application requirements for the three RUP dicamba products are covered in this FAQ.
Pollen-mediated gene flow at a distance could allow the spread of rare herbicide-resistant alleles and favor the evolution of multiple herbicide-resistant biotypes through the accumulation of different resistant genes in an individual weed or weed population.
