At an upcoming waterhemp management plot tour on O’Brien Family Farm in Brooklyn, Wis., I’ll be hearing from Rodrigo Werle, weed scientist at the University of Wisconsin-Madison, as well as others as they walk us through their weed suppression research. 

This is a look at the university’s cereal rye weed suppression research, featured at the 2023 plot tour. I’ll have an update on that in the coming weeks.  

“This was treated about 20 days ago with 32 fluid ounces of Liberty plus 3 pounds of AMS 15 GPA. And here is what we are seeing 20 days after. My next treatment here is Enlist. Enlist was sprayed about twenty days ago — 32 fluid ounces of Enlist 1 or 2,4-D choline, 15 GPA and 2 pounds of AMS. Now I am going to walk you to one of the treatments where we just mix the two treatments together because that has been a common question for our growers — should we be mixing Enlist and 2,4-D, and this is what we are seeing here. So this is the plot where we mixed Enlist 1, which is 2,4-D choline, plus Liberty, which is glufosinate, together so 32 and 32 fluid ounces of each product, plus 3 pounds of AMS, and here you see the excellent control.”

You can catch Rodrigo Werle at the 2024 National Strip-Tillage Conference in Madison, Wis., on Thursday, August 8 as he gives a presentation about applying integrated weed management in strip-till systems, or tune in to the next episode of Conservation Ag Update to see the results from the 2024 trials.
