Aaron Hager, PhD
University of Illinois Targets Weed Control Approaches
Manage Weeds to Protect Soybean Yields
Aired: June 2013
Weed control is one of the most critical factors for preserving the yield potential of your crops. As more Illinois farms experience resistant weeds farmers will need to take new approaches to weed management; checkoff-funded research continues to provide new recommendations for a more complete and effective weed management plan.
Listen to Aaron Hager, PhD., discuss the research findings and practices farmers can implement now to manage weeds more effectively.
- Understand the biology of the weeds already present in the field.
- Use a diversified approach to weed management that focuses on preventing seed production and reducing the seed bank already in the soil.
- Use an effective burndown strategy for growers who are planting in weed-free fields.
- Plant weed-free crop seed.
- Scout fields regularly during the season to keep an eye out for weeds that might have survived early-season application work.
- Use multiple modes-of-action herbicides that are effective against the most troublesome weeds.
- Apply herbicides at the recommended label rates and for the recommended weed sizes.
- Use mechanical weed control methods along with biological ones when it is appropriate to do so.
- Prevent field-to-field movement of weed seed by cleaning equipment before it moves out of a particular patch of land.
- Manage weed seed spread at harvest time.
- Prevent an influx of weed seed by monitoring field borders (where potential resistant weeds might have been missed during any in-season application work).
