Although glyphosate provided superior weed control in the early years, most of the weeds in the dataset showed signs of adaptation to the chemical in just two to three years.
Vanessa Corriher-Olson, Ph.D., Overton, and Jamie Foster, Ph.D., Beeville, said careful management early in a drought can minimize long-term stand damage and help maintain forage yields when rains do come.
This webinar explores the current situation with herbicide resistance in North America, discusses some smoking guns out there that are increasing the problem, and delves into some strategies for farmers to incorporate on their farms to combat this on going challenge.

Glyphosate-resistant horseweed, or marestail, remains one of the primary weed management challenges in no-till soybean production. Designing effective herbicide control strategies for horseweed is challenging because of its emergence patterns. Read more in this article from Penn State University Extension.
Recent studies defending the use of occasional tillage are interesting reads but leave a lot of questions and problems with this approach that are left unaddressed. Read on to see why you should keep the tillage equipment in your shed.
Seeking to better understand herbicide resistance, researchers exposed more than 70 million grain amaranth seeds to a soil-based herbicide. Though preliminary, the findings suggest that the mutation rate in amaranth is very low, and that low-level herbicide application contributes little — if anything — to the onset of new mutations conferring resistance, say researchers at the University of Illinois.
A primary principle in no-till farming is that tillage dramatically disturbs the soil, decreasing water infiltration capacity and increasing the likelihood of erosion, and yet many farmers continue to use tillage to deal with weeds that would otherwise hamper crop production in their fields. A no-till system offers techniques for killing weeds which do not destroy the structure of the soil the way tillage does.
Dawn Equipment Co. unveils its RowMow weed management system, ideal for an organic no-till soybean system. Two levels of triangle-shaped blades mow weeds between rows and above.

On this episode of Conservation Ag Update, brought to you by Titan International, we catch up with young Kentucky no-tiller Quint Pottinger to see how he autonomously planted his entire crop in 2026. Senior editor John Dobberstein checks in from the CTIC Conservation in Action Tour in Scotland Neck, N.C., where no-tiller Zeb Winslow III talks about his multi-species cover crop program.
We have engineered and developed the most advanced concave system that threshes all crops, eliminates rotor loss, improves grain quality, gives you a cleaner sample – all with one set of XPR concaves.
