Weed Control for No-Till Soybeans

Regain control of your fields with Sharpen herbicide


The wet conditions experienced by many growers in the Midwest during the 2019 season may be behind us, but the effects will be long-lasting. Delayed planting and unusually high prevent plant acres left growers no choice but to abandon their preferred herbicide program compromising the timing and success of their weed control practices.


The issue with the high number of prevent plant acres combined with delayed planting is twofold. On prevent plant acres many growers were not able to effectively control weeds leading to an increase in the weed seed bank that will be problematic throughout the 2020 season. Additionally, later planting led to a delayed harvest preventing growers from applying a fall burndown treatment. This places increased pressure on current technologies and trait systems at planting because winter annuals and early emerging spring weeds will be more prevalent and tougher to control. To avoid an especially difficult and weedy season, no-till growers must use an effective burndown herbicide this spring to control emerged weeds.


“Every season, there are elements growers can’t control, but starting with clean fields is the best way to set themselves up for success,” said BASF Technical Market Manager Andrew Adams. “If growers, particularly no-till growers, didn’t have a chance to apply a burndown herbicide following harvest, they should incorporate a burndown like Sharpen® herbicide on their soybean fields before planting.”


Powered by Kixor® herbicide technology, Sharpen herbicide works quickly, driving burndown three to five times faster than 2, 4-D or glyphosate.1 The herbicide provides flexible burndown of broadleaf weeds when applied preplant and/or preemergence, controlling:

  • Bedstraw
  • Common mallow
  • Dandelion
  • Horseweed (marestail)
  • Kochia
  • Mustard (black, wild, tumble)
  • Narrowleaf hawksbeard
  • Prickly lettuce
  • Russian thistle
  • Wild buckwheat
  • Common lambsquarters
  • Pigweed spp


Key components of any effective weed management strategy today must include multiple effective modes of action, as well as multiple application timings. Sharpen herbicide allows growers the flexibility and confidence to start clean with a robust burndown program, regardless of the trait platform they choose.


“Because of the delayed harvest, we’re going to see a lot of weedy fields with a larger, denser weed canopy, especially in no-till and prevent plant acres,” said Adams. “Growers should be sure to include both pre- and postemergence herbicides, targeting small weeds, abiding by the labeled rate, and including residuals and post herbicides for longer control.”


An additional benefit of starting with a burndown like Sharpen herbicide is that cleaner fields allow no-till growers an earlier planting window and improved operational efficiency. For best performance, burndown herbicides should be applied when weeds are small and actively growing. Then, growers should follow up with additional herbicide applications in accordance with their long-term weed management plan.  To learn more about Sharpen herbicide, talk to your local BASF representative, or visit SharpenHerbicide.com.
