New ‘Focus on Cotton’ Webinar Helps Growers Manage Herbicide-Resistant Pigweed Populations

Glyphosate-resistant pigweed (Palmer amaranth) can quickly overtake a cotton field if not managed properly and thoroughly.

A new Focus on Cotton webcast titled “Zero Tolerance: Designed for Seedbank Reduction” helps cotton growers, consultants, and other industry experts employ manual control methods to limit pigweed plants from dropping seed and contributing to the soil seedbank—effectively reducing the potential for future outbreaks due to its short seed viability.

This 27-minute talk by Tom Barber, Professor and Extension Weed Scientist at the University of Arkansas, provides information that helps users: 

  • Recognize pigweed’s aggressiveness and weaknesses
  • Adopt and execute ‘zero tolerance’ management practices
  • Reduce future pigweed outbreaks and herbicide resistance
  •  This presentation is available at no charge, courtesy of Cotton Incorporated, through the ‘Focus on Cotton’ webcast resource located at the Plant Management Network,  ‘Focus on Cotton’ contains over 35 webcasts on various aspects of cotton crop management.
