A season-long approach that relies on multiple herbicide modes of action is important. Ryan Miller, Ph.D., market development and new technology specialist, highlights a few additional tips for a successful weed control program. Farmers who remain diligent can control their most challenging and stubborn weeds.
Here are Miller’s six suggestions for developing an effective weed control strategy:
- Know the field history. It’s important to know what weeds have been in the field, especially during the previous year, when implementing a weed control program. If a field harbors resistant marestail, Palmer amaranth or any other tough weed, make sure to use herbicides that are effective against those species.
- Start with a clean seedbed. Aim for a weed-free field at planting. Consider a burndown program that targets key weeds. Glyphosate and 2,4-D often are effective burndown options.
- Use herbicides with residual activity. Add residual herbicides for additional modes of action that help control weeds in the current year and preserve the efficacy of postemergence herbicide technologies.
- Rotate modes of action. Rotating modes of action helps prevent the development of herbicide resistance. Scout fields and, when weeds emerge, hit them with postemergence herbicides that deliver more than a single mode of action, whether with a tank mix or a pre-mix product. Enlist Duo® herbicide, consists of new 2,4-D choline and glyphosate, while Enlist One™ herbicide is a straight-goods 2,4-D choline that allows you to tank-mix with other effective partners such as glufosinate. Both Enlist Duo and Enlist One feature Colex-D® technology, which reduces drift and provides near-zero volatility.
- Keep field borders clean. It’s important to control weeds in ditches and turnrows to prevent weed escapes. Weeds in these areas may develop resistance because they often avoid exposure to full rates of effective herbicides.
- Adopt a zero-tolerance policy. Controlling weeds effectively throughout the growing season is essential to curbing the expansion of herbicide resistance.
It’s vital to be good stewards of effective herbicides. This will preserve their efficacy as we strive for long-term weed control.
Sound weed management plans are critical to boosting opportunities for long-term profitability. The best practice is to keep the farm free of weeds. A field that’s clean helps protect more of the yield potential of every seed planted.
