As glyphosate-resistant pigweed spreads throughout the Mid-South, growers are having to develop new strategies for weed control and pull some old tools from the closet.

If you want to arm yourself with the latest information on control, be sure to attend the PigPosium Nov. 17, at 8:45 a.m., at East Arkansas Community College, Forrest City, Ark.

The University of Arkansas Cooperative Extension Service and Delta Farm Press are presenting a one-day seminar of reports and recommendations from a blue ribbon panel of weed scientists and other experts.

PigPosium topics include best management practices for control of pigweed in soybean and cotton, economics of pigweed management, wick applicators, crop rotation and new technology. (Tell us which strategies are most important in our latest DFP Poll.)

Experts will also discuss the characteristics of glyphosate-resistant pigweed. Before you put together a plan for control, be sure to sit in on this session to gain a better understanding of pigweed’s growth and reproduction requirements.

Other weed scientists, including Nilda Burgos, University of Arkansas, Larry Steckel, University of Tennessee and Jason Bond, Mississippi State University, will help producers understand how glyphosate-resistant pigweed developed in the Mid-South.

The PigPosium will wrap up with a panel discussion on managing the soil seed bank and farmer programs that work, and conclude by 3 p.m.

That panel will include Mid-South farmers David Wildy and Adam Chappell, as well as Arkansas weed scientists Jason Norsworthy, Bob Scott and Ken Smith. They’ll describe their research on aggressive control techniques such as tillage and cover cropping, overlapping residuals and hand chopping.
