Recent warmer temperatures and adequate moisture have set the stage for rapid weed growth in the coming weeks. Timely and effective herbicide applications will carry much of the weight in […]
Iowa: Weed Science Field Day, Ames, July 14 May 27, 2022
This year’s Weed Science Field Day will be held on Thursday, July 14 at the Iowa State University Curtiss Farm, Ames, IA. Although the 2022 cold and wet spring has […]
This spring’s weather has resulted in an unusually slow start to the growing season, especially when compared with the past two years. In springs like these, field operations are condensed […]
One of the topics that we get many questions about is picking a residual herbicide for soybean production that helps with waterhemp control.
University of Illinois weed scientists have confirmed resistance to the herbicide dicamba in a Champaign County waterhemp population. In the study, dicamba controlled 65% of the waterhemp in the field […]
Tennessee: Dicamba-Resistant Waterhemp Confirmed Nov 12, 2021
Results from greenhouse experiments and in-field research this summer confirm that our state now has dicamba-resistant (DR) waterhemp. Moreover, our survey of weed escapes this fall sponsored by the Tennessee […]
Catching weed seeds before they start a new generation of herbicide-resistant plants is the tactic behind a relatively new method in the United States that weed scientists in Arkansas, Iowa, […]
Scientists in Tennessee and Illinois have confirmed dicamba-resistant waterhemp populations.
Waterhemp is a new weed to North Carolina. It looks a lot like the other pigweeds- redroot pigweed and Palmer amaranth. Waterhemp often already has herbicide resistance. This short video […]
With support from the United Soybean Board, in 2019 and 2020 we conducted a screening of 212 waterhemp populations from 7 different states to characterize their abilities to withstand applications […]
