Including on-site demonstrations of projects for control of
Glyphosate-Resistant Palmer amaranth in Soybean
- Palmer amaranth, a member of the pigweed (Amaranthaceae) family, is one of the most troublesome weeds in soybean fields.
- Greenhouse dose-response studies have confirmed glyphosate-resistant Palmer amaranth in Nebraska.
- Field experiments will demonstrate how to control resistant Palmer amaranth in field and seed corn production fields in Nebraska.
ON-SITE DEMONSTRATION OF PROJECTS
- How row spacing and herbicide programs can affect glyphosate-resistant Palmer amaranth control in Roundup Ready 2 Xtend Soybean
- Management of Palmer amaranth in
- Balance GT/Liberty Link Soybean (resistant to isoxaflutole and glufosinate)
- Enlist E3 Soybean (resistant to 2,4-D choline, glyphosate, and glufosinate)
- Critical period of Palmer amaranth removal affected by residual herbicides in Roundup Ready 2 Xtend Soybean
Jason Norsworthy is a Professor and the endowed Chair of Weed Science at the University of Arkansas. He grew up on a vegetable farm in southern Ar-kansas, where he quickly learned the need for weed management in crops. Norsworthy has documented eight herbicide-resistant weeds in Arkansas, includ-ing glyphosate-resistant Palmer amaranth. He has been invited nationally and internationally to present his research on management of resistant Palmer amaranth. He presently serves as Editor-in-Chief for Weed Technology, a journal of the Weed Science Society of America that publishes applied weed science research.
