A great way to start the soybean season with a clean slate is to make an early spring burndown application. So, you may be wondering what will work best to burn down the weeds on your farm. If you’re dealing with a mix of grasses and broadleaves (marestail in particular), we have some suggestions for you.

Recipe for a Good Burndown

Historically, many farmers have relied on an early spring burndown mix of glyphosate and dicamba to control broadleaf and grass weeds in their soybean fields. However, over the years, a large swath of the weed spectrum has developed resistance to glyphosate. This is likely something you’ve noticed on your own operation.

The problems go beyond glyphosate resistance. 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 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. Unfortunately, this mix won’t necessarily control all the weeds you need to control, Steckel says. He explains glyphosate and clethodim can be weak on some broadleaves, particularly glyphosate-resistant marestail (horseweed).

Elevate Your Burndown

In his article, Steckel says he’s heard from many farmers asking what they can add to this burndown mix that will control those broadleaves without sacrificing control of grass weeds. 

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 include in an early spring burndown, because it controls broadleaf weeds — especially marestail — well without antagonizing ryegrass control from glyphosate/clethodim. 

Here is what you need to know about Elevore:

  • The active ingredient in Elevore, Arylex® active, provides thorough control of labeled broadleaf weeds, including marestail (horseweed), without regrowth. In fact, the solution can control marestail up to 8 inches tall.
  • Elevore has a low use rate of 1 ounce per acre, making it a great fit if you have a reduced- or no-till operation.
  • Elevore is tank-mix-compatible with many commonly used burndown and residual partners, including glyphosate. 
  • Elevore can be applied up to 14 days before you plant soybeans.


If you’re dealing with broadleaf and grass weeds this spring and you need a good burndown mix to clean them up, Elevore, clethodim and glyphosate could be just the ticket. Talk with your local ag retailer about using Elevore on your soybean fields this spring.
