The mission of the Cornell Weed Management Extension Program has been to evaluate weed management strategies for agronomic crops in New York State, to incorporate these research results into management guidelines, and to conduct educational programs on the implementation of these guidelines. Research is focused on chemical and cultural weed management practices including herbicide evaluation for control of problem weeds such as triazine-resistant annual weeds, control/management of perennial broadleaf weeds such as hedge bindweed and dandelion,use of perennial forage grasses to suppress weeds in alfalfa, evaluation of buckwheat as a nurse crop during establishment of perennial forages and as a cover crop for weed suppression between crops, and development of weed control programs for conventional and genetically modified corn and soybeans.
