This is an older report. I have seen more recent reports linking Triclopyr to cancer. Clopyralid & Triclopyr The Deadly Duo Clopyralid and triclopyr are two powerful weedkillers used to manage unwanted plants in lawns and turf, pasture, rights-of-way and various crops. Dow AgroSciences formulates these chemicals together for non-agricultural uses in a product called Confront, and alone in Lontrel (clopyralid) and Turflon (triclopyr). For agricultural uses, both chemicals are formulated in various products with other herbicides such as 2,4-D (see p. 3). Transline (clopyralid) is commonly used for invasive plant management. HEALTH AND ENVIRONMENTAL CONCERNS EPA tests show that clopyralid causes “substantial” reproductive problems, including reduced fetal weight, skeletal abnormalities, and hydrocephaly (accumulation of excess fluid around the brain). In laboratory tests, triclopyr causes a significant increase in the incidences of breast cancer and genetic damage in rat embryos. Studies also link triclopyr to kidney and reproductive problems. In 2002, Dow agreed to delete all residential uses from the label of clopyralid products after numerous studies documented widespread contamination of compost with high levels of clopyralid. This has led to further restrictions in New York, California, Oregon and Washington. Studies have shown both triclopyr and clopyralid to be very stable in soil with the potential to leach into groundwater and contaminate surface water. EPA has not evaluated the carcinogenic potential for either clopyralid or triclopyr. KEEP CLOPYRALID AND TRICLOPYR OUT OF YOUR... COMMUNITY Used on: golf courses, parks, schools, rights-of-way, and for invasive plant control. What You Can Do: Contact your local schools, parks and golf courses, and ask them to not use Confront or Lontrel on their lawns. Alert them to the dangers of clopyralid and triclopyr, and recommend an integrated pest management program that uses pesticides only as a last resort. Effective management techniques that include organic products and cultural practices prevent unwanted plants and eliminate the need for toxic chemicals. Ask golf course managers and park and school superintendents to only use and/or hire service providers that use organic and least- toxic techniques and cultural practices. As an alternative for park and schoolyard uses, recommend corn gluten (Bio-Weed, Concern and GreenSense) as a pre-emergent herbicide and Fatty-acid soap (Safer, Sharpshooter). For invasive plants, recommend an integrated plant management program that focuses on mechanical methods, grazing, biological controls, soil health and native plant restoration, and adopts an ecological-based holistic approach to land management. FOOD Used on: wheat, barley, rice, field corn, sugar beets and oats. What You Can Do: Buy organic food products whenever possible. Contact the Pepperidge Farm Company, 595 Westport Avenue, Norwalk, CT 06851, 888-737-7374, and ask the company to stop buying wheat sprayed with clopyralid and/or �������
