Field Crop Weed identification and control Series 2022 (virtual)
Lynn Sosnoskie, Asst. Prof. of weed ecology and specialty crop systems, Cornell
Weeds are a significant threat to crop production due to 1) competitive interactions that limit yield potential, 2) physical interference that reduces harvest efficiency, and 3) serving as an alternate host for pests and pathogens. The evolution of herbicide resistant weeds (in particular marestail/horseweed/Canada fleabane, Palmer amaranth, waterhemp) further complicates weed control efforts by limiting the utility of commonly applied chemical tools. This talk will focus on the current state of herbicide resistance in NY and the future of chemical weed control. Novel weed management strategies, such as harvest weed seed control (HWSC) and electrical weeding will be discussed and recent research updates provided. Best management practices for suppressing unwanted vegetation, including combine and equipment clean-out to limit seed spread, will also be presented.
