We’re very lucky to have on the show two well-respected agronomic experts to talk about current weed management challenges. They share with us the weeds that have been the most difficult to manage, how high prices and supply chain challenges are impacting the tools farmers have at their disposal, and what the future of weed control looks like.
Joining me today are Joe Ikely, extension weed specialist at North Dakota State University, and Jason Hanson, owner and operator of Rock N Roll Agronomy. Joe’s work includes both extension and research in weed control with an emphasis on corn soybeans and dry beans. Jason is an independent crop consultant working directly with farmers as well as consulting with ag retailers on a contract basis.
“Kochia, that's definitely from my perspective, the top weed issue of this year….kind of a reminder for those who haven't had to battle kochia for a while, that once we get dry conditions, there's still plenty of plants around producing seeds, spreading them around.” - Joe Ikely
What makes Kochia unique is the ability to develop an “aggressive root system” that will reach and take advantage of any moisture available. When the climate is dry, the crops struggle to compete with that root system. Compounding the issue for producers is herbicide resistance limiting the efficacy of inputs. These factors have impacted farming practices this year and are expected to continue next year.
“Now I've got a higher (kochia) population. There's definitely more kochia that has been cut, harvested and is rolling and tumbling around the countryside on some of our windy days. So we'll definitely have more pressure to deal with in 2022.” - Jason Hanson
