1747 - Here's a compelling reason to consider organic gardening and landscaping at home: low-dose exposure to lawn care pesticides my cause injury to developing embryos before pregnancy is even noticed. That's according to a new study recently released by researchers at the Marshfield Clinic Research Foundation (MCRF) in Marshfield, WI, a system of 40 patient care and research and education facilities in Wisconsin. MCRF conducted the study because little is known about residential use of pesticides and their possible effects on embryonic development during the first few days of pregnancy. The study's general use of the term "pesticides" refers to a host of herbicides (weed killers), insecticides (insect killers), fungicides (fungus/mold killers) and fertilizers. The active ingredients studied include six herbicides (atrazine, dicamba, metolachlor, 2,4-D, pendimethalin, MCPP) three insecticides (chlorpyrifos, terbufos, permethrin) two fungicides (chlorothalonil, mancozeb) one drying agent (diquat) and one fertilizer (ammonium nitrate). The chemicals are typical of those used in the upper Midwest. Lawn pesticides studied are typical of those used throughout the United States.
