"This manuscript was presented at the First International Symposium on Watermilfoil held in Vancouver, BC, in July 1985. It will be published in the Proceedings of that Conference, and the contents are subject to change". Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "The recent invasion of Canadian waters by Eurasian watermilfoil has resulted inincreased use of the herbicide 2,4'—D and increased public concern with the safety of such chemical control measures. This study was an Environment Canada response to such concern expressed in areas as diverse as the Trent-Rideau-Severn waterway and the Okanagan Lakes in British Columbia. Our study was designed to determine the fate and impact of the butoxyethyl ester and I N,N-dimethylarnine formulations of 2,4“-D. The ester is the only approved formulation in Canada for aquatic use, and the amine was being considered by Agriculture Canada as a replacement. This report summarizes two previous reports and is intended as a synopsis of Environment Canada's research on 2,4-D in artificial pond ecosystems"--Exec. summary.
