Funding from New York Corn & Soybean Growers Association Soybean Checkoff will greatly aid to assess the frequency and distribution of herbicide-resistant tall waterhemp and Palmer amaranth populations across NY soybean fields to most frequently used herbicides. This information in conjunction with periodic monitoring would also help to identify any shift in herbicide susceptibility of these two newly invaded pigweed species in NY soybean fields. Findings from this herbicide resistance screening will aid in further work and research efforts aimed at utilizing integrated herbicide programs (PRE and POST) for tall waterhemp and Palmer amaranth management in Enlist soybean production systems. This research will provide answers to the producer-based question: What is the current status of herbicide-resistant pigweeds (tall waterhemp and Palmer amaranth) and how can those herbicide-resistant biotypes be managed in NY soybeans. The ultimate goal of this project is to improve the sustainability and economic viability of current weed management systems for NY soybean producers.
