Integrated management of pastures and hayfields sometimes require the application of broadleaf herbicides to manage weeds. Weed infestations are usually caused by a variety of factors including but not limited to drought, poor grazing management, and feeding weed infested hay in pastures. Weeds can adversely affect livestock access to forage as well as reduce forage quantity and quality. Producers are often hesitant to apply herbicides to manage weeds because of the effect the herbicides will have on forage legumes present in the pasture.
