Liberty-resistant Palmer amaranth confirmed in Arkansas
Joshua Putman, Field Crops and Forage Specialist
Southwest New York Dairy, Livestock and Field Crops Program
Researchers from the University of Arkansas have identified Palmer amaranth populations that survived several applications of Liberty (glufosinate) Herbicide. Seed was collected and tested in the greenhouse showing a resistance of 16 times the typical field use rate. These findings represent the first documented case of a broadleaf resistance to Liberty Herbicide in the world. Liberty link traits are an additional tool to help corn and soybean producers control problematic weeds like Palmer amaranth, waterhemp, and marestail. Palmer amaranth is now present in 3 counties in New York State, one of which is in Southwest NY. Seed was collected from these populations in the fall of 2020 and are being tested for resistance to our commonly used herbicides. Stay tuned as we conduct research on these NY populations.
