Many growers know from experience that glyphosate-resistant pigweed (Palmer amaranth) can quickly overtake a cotton field if not managed properly and thoroughly.
A new webcast – titled “Zero Tolerance: Designed for Seedbank Reduction” – has been added to the Focus on Cotton online series from the Plant Management Network and Cotton Incorporated.
This 27-minute talk by Tom Barber, professor and Extension weed scientist at the University of Arkansas, provides information to help 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.
During the presentation, Barber provides information to help viewers recognize the aggressiveness and weaknesses of pigweed, adopt and execute “zero tolerance” management practices, and reduce future pigweed outbreaks and herbicide resistance.
This webcast is part of the Focus on Cotton series made available by the Plant Management Network and Cotton Incorporated. The Focus on Cotton series contains more than 40 webcasts on various aspects of cotton crop management, including agronomic practices, crop protection and ag engineering. The presentations are accessible online at any time.
The resource also features a newly improved Cotton Extension Search tool, where users can conveniently search for extension resources across all U.S. land-grant universities serving cotton producers.
