3 tips for fighting herbicide resistance in wheat

April 28, 2016

We’ve mentioned before that it’s important to prevent weed seed bank build up and make an effective herbicide application, but what else goes into fighting herbicide resistance? Syngenta outlines 3 important tips to help fight herbicide resistance:

  1. It’s all about herbicide timing

Many variables impact herbicide application timing, including planting date, soil temperature, and amount of rainfall that occurs both before and after planting. By utilizing a post-emergence treatment, growers ensure overlapping coverage that keeps fields protected season long.

  1. Full, recommended herbicide rates help delay onset of resistance

Help prolong the effectiveness of available herbicides and delay the onset of resistance in wheat fields by utilizing herbicides with different modes of action and using the full recommended rates.

  1. Diversify modes of action to reduce the risk of herbicide resistance

In addition to using full rates, it’s also important to diversify herbicide modes of action (MOA). Syngenta offers a robust portfolio of cereal herbicides that include multiple grass, broadleaf and cross‐spectrum options with varying MOAs including:

  • Axial® XLand Discover® NG herbicides for excellent control of grass weeds
  • Sierra™and Axial Star for cross-spectrum options and the ability to tailor weed control programs to the specific spectrum in each field
  • Orion®herbicide for highly effective control against yield robbing broadleaf weeds, and an effective tank-mix partner with Axial brands for one-pass grass and broadleaf weed control

Pending registration for the 2017 growing season, Talinor™ herbicide will deliver excellent standalone control of resistant and other tough-to-control broadleaf weeds in barley, spring wheat (including durum). It contains the newest active ingredient in cereal herbicides, bicyclopyrone, combined with bromoxynil, to deliver excellent standalone control of resistant and other tough-to-control broadleaf weeds, including kochia and Russian thistle.

Proactive practices can help minimize the evolution of herbicide resistance in wheat fields. Remember when applying herbicides that timing, using the full recommended rates and utilizing different MOAs will help fight herbicide resistance and ultimately grow more wheat.
