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.

NY Small Farms Summit 2025: Stronger Together
December 5, 2025
Alfred, NY
We hope you will join us on December 5th for the 2025 New York Small Farms Summit! This is an opportunity to meet other farmers and ag supporters, learn about research and education projects, and set priorities for future efforts to grow small farm success.
At the Allegany County site, we will focus on giving trees a chance and how trees build resiliency on small farms. Whether attracted to fruit, nuts, vegetables, fodder or shade, trees can be an integral part of a successful farming system. Join us as we explore the opportunities for resiliency that come from adding tree crops or managing wooded areas of your farm for agroforestry or silvopasture systems.
