(Beyond Pesticides, September 17, 2014) DuPont agreed to pay the U.S. Environmental Protection Agency (EPA) $1.853 million to settle charges from the agency that the chemical giant’s herbicide product ImprelisTM was responsible for killing and damaging thousands of acres of spruce and pine trees in 2011. On Monday, EPA filed a Consent Agreement and Final Order against DuPont for violations of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) for selling and distributing its pesticide product -ImprelisTM herbicide. EPA contends that DuPont failed to submit in a timely manner field trial studies indicating potential ecological adverse effects from the use of Imprelis. In 2011, in what some say was one of the biggest disasters of its kind, Norway spruce and white pine tree damage and deaths were reported throughout the Midwest, in East Coast states, and as far south as Georgia. It was determined that Imprelis, marketed as a “low environmental impact” pesticide, was applied during the spring to control weeds on lawns and other landscapes in the vicinity of the non-target evergreen trees. Imprelis, whose active ingredient is the potassium salt of aminocyclopyrachlor, was conditionally registered by EPA in September 2010, in a regulatory process reminiscent of […]

(Beyond Pesticides, August 6, 2010) Organic farmers and gardeners across a Washington state county suspect that herbicide-contaminated manure and compost obtained from non-organic farms and dairies are responsible for severe crop loss reported throughout the region, raising questions about the adequacy of the U.S. Environmental Protection Agency’s (EPA) pesticide registration process. Tests of soil and tissue samples of local dairy manure that is used in soil and compost mixtures revealed small amounts of aminopyralid, a potent and persistent herbicide approved for use by EPA in 2005. Aminopyralid is generally used for weed control in pastures and fields that grow silage crops for dairy cows. When cows eat the grass that has been treated with the chemical, it passes through them unchanged and remains in their manure in concentrations that can still be high enough to damage broadleaf crops if the manure is used to fertilize them. Aminopyralid is produced by Dow AgroSciences, a subsidiary of Dow Chemical Co., and often manufactured under the product name Milestone. Former coordinator of the Washington State University master gardeners’ program Jill Cotton has noticed the damage in her garden and said reports continue to filter in from other gardens around the county.

(Beyond Pesticides, July 2, 2008) Gardeners in the United Kingdom (UK) have been warned not to eat home-grown vegetables that have been exposed to the new and persistent herbicide, aminopyralid. Domestic gardens and allotments have been contaminated by manure originating from farms where the herbicide aminopyralid was sprayed on fields. All across the UK harvests of withered and rotten potatoes, beans, peas, carrots, salad vegetables and deformed tomatoes have been reported by confused and angry gardeners. It is believed that contamination of manure arose after grass was treated with aminopyralid 12 months ago. Experts say the grass was probably made into silage, and then fed to cattle during the winter months. The herbicide remained present in the silage, passed through the animal and into manure that was later sold. Aminopyralid is gaining popularity with farmers, who spray it on grassland to control weeds such as docks, thistles and nettles without affecting the grass around them. Dow AgroSciences, which manufactures aminopyralid, has made a statement on their website saying: ‘As a general rule, we suggest damaged produce (however this is caused) should not be consumed.’ Those who have already used contaminated manure are advised not to replant on the affected soil […]
