Ask most Mid-South and Southern soybean growers what their most troublesome weed is, and they’ll say Palmer pigweed—also known as Palmer amaranth. Not only is the weed inherently difficult to control because of its prolific seed production, but now in many areas it has become resistant to glyphosate and a host of other herbicides.

The latest Web seminar from Focus on Soybean, titled “Row Spacing and Seeding Rate and Affects on Weed Management,” discusses taking an integrated weed management approach.

Developed by Shawn P. Conley, Extension Specialist at the University of Wisconsin–Madison, the seminar includes information about the:

  • Benefits of diversifying management strategies
  • Advantages of herbicide rotation and pre-emergence applications
  • Effectiveness of adjusting row width and seeding rates

The 26-minute presentation will remain open access in the Focus on Soybean webcast library courtesy of the United Soybean Board.

Focus on Soybean is produced by the Plant Management Network, a nonprofit collaboration among the American Phytopathological Society, American Society of Agronomy and the Crop Science Society of America.
