Download PDF


Glyphosate-resistant Palmer amaranth (also known as pigweed) continues to be a major problem for cotton producers across Georgia. Roundup-, Liberty-, or Roundup plus Liberty-based programs are provided in this publication and are developed from years of research. However, keep in mind programs should be adjusted for each farming operation. In addition to these programs, growers share the top six factors that have helped them improve Palmer amaranth control. Programs for dicamba or 2,4-D will be provided on a separate circular when those products receive registration. Generic products are available for Direx, Dual Magnum, Gramoxone, Liberty, Prowl, Reflex, Staple, Treflan and Valor. Read and follow all label requirements.
