Includes bibliographical references. "This work evaluates the losses of atrazine and metolachlor in transient runoff eventsfrom an agricultural watershed. Twenty-five runoff events monitored in this watershed during 1990 and 1991 were used for the evaluations. The evaluation identified that majority of the losses of atrazine and metolachlor occurred within 70 days of application and during a large storm event, shortly after a herbicide application. The surface runoff combined with interflow is a major pathway for the losses of the two herbicides. The results of this work are useful for fine-tuning of agricultural practices and for watershed management considerations in the protection of water quality of the Great Lakes Basin.
