Download or read book Low Herbicide Concentration Found in Streamflow After a Grass Cover is Killed written by and published by . This book was released on 1969 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: The grass cover on a steep Appalachian watershed was sprayed in 1966 with herbicides--first with atrazine and paraquat and later with atrazine and 2,4-D. Although grass growing in the stream channel was sprayed during the first treatment, atrazine and paraquat levels in water samples were low. for the second treatment, a 10-foot strip on either side of the channel was left unsprayed. No increase in atrazine concentration was noted, and no 2,4-D was detected. Thus, use of these chemicals does not appear to constitute a water pollution hazard when reasonable care is taken to protect streamside vegetation and the stream from direct contamination.
