Brief Project Summary:

The PRE's that provided the best residual control regardless of soil type of GR Palmer amaranth were Prefix, Authority MTZ and Boundary. A PRE applied herbicide that provides about four weeks residual control coupled with post applied herbicides on small Palmer (<3) was the best program. Pyroxasulfone a new herbicide in our research provided good residual Palmer control. We also evaluated a number of Liberty based systems in Liberty Link soybeans. Those systems where a PRE was followed by two applications of Liberty provided the most consistent Palmer control. This data has helped lay the foundation for the Palmer amaranth control section of the TN Weed Control Manual. Studies were conducted...
