When it comes to starting your customers’ soybean fields off right, an early spring burndown application is almost always a good idea. If the weather conditions and timing allow for it in 2022, an early spring burndown will give farmers a clean slate ahead of planting, paving the way for their preemergence herbicide applications.
Historically, many farmers have relied on an early spring burndown mix of glyphosate and dicamba to take care of broadleaf and grass weeds. However, over the years, a large swath of the weed spectrum has developed resistance to glyphosate.
The problems go beyond that resistance, too. Larry Steckel is an Extension weed specialist at the University of Tennessee Institute of Agriculture. In the article "A Shift in Early Burndown Strategy," Steckel explains that dicamba has been found to antagonize glyphosate, causing poor control of grass weeds like ryegrass, junglerice and johnsongrass.
That’s why, Steckel says in the article, he now recommends a mix of glyphosate and clethodim for early spring burndown applications. This mix isn’t perfect either though, says Steckel, who explains that it can be weak on some broadleaf weeds, particularly glyphosate-resistant marestail (horseweed).
In his article, Steckel says several farmers asked him last year what they can add to their burndown mix that will help control broadleaves without sacrificing control of grasses.
One of Steckel’s recommendations is Elevore® herbicide. He says he reviewed several data sets that were specifically related to Italian ryegrass and found Elevore to be a good choice to add to the early spring burndown mix, because it controls broadleaf weeds well without antagonizing ryegrass control from glyphosate/clethodim.
Here are some fast facts about Elevore:
If your farmers are looking for an addition to their early spring burndowns that will offer strong broadleaf control and allow for good grass control, Elevore could be a great choice for them. Talk with your local Corteva Agriscience representative about using Elevore on your customers’ soybean fields this spring.
