Burndown benefit: The early bird gets the weed

Weeds are becoming more persistent. As more farmers adopt minimum-tillage programs, weeds are coming up earlier and thicker. With more weeds developing resistance to certain herbicides, an effective burndown program is almost essential to a successful campaign against weeds.

“Starting with a clean field is paramount to maximizing the yield potential in today’s production systems,” says David Hillger, Ph.D., Enlist field specialist. “If you allow weeds to have a head start, no matter how small they are, they can rob potential profit from your operation.”

It’s a classic case of “if you snooze, you lose.” Sure, weather and other farm-related responsibilities can make it difficult for farmers to achieve timely burndowns of every field. But retailers can help remind customers about the importance of starting with a clean field and keeping it clean the entire growing season.

A helpful burndown option
Tyler Tietjen, a Nebraska farmer, used Enlist Duo® herbicide as a burndown last spring. “I want clean fields when I start,” Tietjen says. “I expect the field to be 100 percent clean. Enlist Duo got everything. The field was clean after using it for burndown.”

Hillger encourages farmers to try Enlist herbicides for burndown. Enlist Duo® herbicide contains new 2,4-D choline as well as glyphosate. The combination helps control a broad range of tough and stubborn weeds.

Enlist One herbicide is a straight-goods 2,4-D choline that offers additional tank-mix flexibility. This allows farmers to tailor their burndown program by combining modes of action to target their specific weed challenges.

Get the jump on weeds
“Not having a good burndown program is like beginning a marathon an hour after the starting gun goes off,” Hillger says. “It might be possible to get those weeds back under control, but any delays or missteps makes it more difficult to avoid yield losses due to competition for resources.”

Hillger notes the highest yield potential during the season is when the crop is planted. “Doing whatever we can to give that crop the best opportunity to establish and compete in its surroundings helps us preserve more yield,” he says.

Retailers can help customers design an effective burndown program. Most university websites cite 2,4-D as a growth regulator herbicide that offers effective broadleaf control for burndown applications.

“Using 2,4-D simply works,” Hillger says. “It’s predictable. It’s been a staple of weed control programs for many years.

“The advantages we see with the new Enlist Duo and Enlist One are that you have the proven effectiveness of 2,4-D while gaining the added comfort of lower odor and improved on-target application from the Colex-D technology found in these products,” Hillger says.

Four key benefits
Like those using Enlist herbicides for postemergence applications, farmers who use these products for burndown experience the benefits of Colex-D® technology:

  • Near-zero volatility
  • Minimized potential for physical drift
  • Low odor
  • Improved handling characteristics

“It’s important to get effective herbicide modes of action onto the field early,” Hillger says. “Generally speaking, it’s the early bird that gets the weeds.”
