Tips for Giant Ragweed Management

Apr 28, 2015

ST PAUL, Minn.  -- Giant ragweed is one of the most problematic weeds in soybean producing areas of the United States. Yield losses can approach 100%, and some populations of this weed are developing resistance to ALS, glyphosate, and PPO herbicides, making it even harder to control the damage.

A new Focus on Soybean presentation, titled - Click the following link to find the presentation.

Author Bill Johnson, Professor of Weed Science at Purdue University, discusses the various control methods for minimizing yield losses due to giant ragweed, as well as minimizing weed seed production.

In this webcast, Johnson particularly covers:

  • The importance of proper burndown herbicide selection
  • Postemergence application timing
  • The integration of burndown, residual, and postemergence herbicides for effective control throughout the season
