Oregon Officials Finalize Restrictions on Bayer’s Tree-Killing Herbicide, Stop Short of a Full Ban

(Beyond Pesticides, May 16, 2019)  Use of the tree-killing herbicide aminocyclopyrachlor (ACP) is now restricted in Oregon, according to rulemaking finalized last week by the state’s department of agriculture (ODA). While an important step in the right direction, many environmentalists are perplexed by the state’s decision not to proceed with a ban on all uses of the inherently toxic chemical, which has killed thousands of old-growth pine trees along state scenic highways. Over five thousand comments from Oregonians and concerned individuals across the country urged ODA to scrap its convoluted proposed rule and simply eliminate the chemical from state commerce. While advocates will continue to urge ODA to completely eliminate ACP use, the current restrictions did not come without a fight. Public meetings were attended by representatives from the chemical’s manufacturer, Bayer. The company strongly opposed any restrictions on its product, and acted to delay the original implementation date for ODA’s rule. Oregon had intended to finalize the rule in late March. “We were pretty much set to file the final paperwork,” said Oregon pesticide program manager Rose Kachadoorian to The Bulletin. But through the work of its corporate lawyers, Bayer was able to track down an arcane Oregon law that […]

Tell Oregon Department of Agriculture to Ban Tree-Killing Herbicide, Aminocyclopyrachlor (ACP) [Perspective]

(Beyond Pesticides, February 11, 2019) Aminocyclopyrachlor (ACP) is a tree-killing pesticide masquerading as a broadleaf herbicide. The Oregon Department of Agriculture (ODA) has the opportunity to lead the country in banning this inherently dangerous chemical. According to ODA, nearly 1,500 dead or dying trees have been reported along Oregon’s iconic Interstate 20, home to old growth ponderosa pines. Many of these 150- to 300-year old trees are now dead from ACP exposure. ODA indicated that “because [ACP] is a relatively new herbicide it is unknown how many trees stressed from past applications of [ACP] will die in the future.” Even at tiny levels, ACP run-off and drift kills trees. Tell Oregon’s Department of Agriculture to lead the country in completely banning its use. In 2014, DuPont chemical company settled a nearly $2 million lawsuit with the U.S. Environmental Protection Agency (EPA) after the herbicide (under the brand name Imprelis®) was found to kill trees at golf courses, homeowners associations, businesses, and private residences. Despite this history, regulators left ACP on the market. Its use was banned on lawns and turfgrass, but allowed for roadside rights-of-way. A couple years ago, Bayer purchased the rights to ACP from DuPont and continues to market […]

Oregon Temporarily Bans Herbicide Known to Kill Trees… after the Herbicide Is Found to Kill Trees

(Beyond Pesticides, October 5, 2018) The Oregon Department of Agriculture (ODA) is temporarily banning the use of any products containing the herbicide aminocyclopyrachlor to rights-of-way after finding widespread tree deaths along a scenic highway that cuts across the center of the state. While Oregon is the first state to ban the chemical, it is not the first instance of the pesticide killing stands of established, otherwise healthy trees. In 2014, chemical company DuPont settled a class action lawsuit totaling over $1.8 million in civil penalties after its aminocyclopyrachlor product Imprelis was cited for misbranding and failure to report adverse incidents of trees dying after applications. Oregon first encountered evidence of abnormal growths, curling, and die-backs of coniferous trees along roadsides back in 2012. A report on tree damage produced by ODA in 2015 narrowed the cause down to the use of aminocyclopyrachlor-based herbicides, including DuPont’s Imprelis, as well as Bayer’s Perspective. At the time, ODA indicated the U.S. Forest Service (USFS) had sent letters to the agency requesting the cessation of aminocyclopyrachlor use along roadsides. Oregon officials indicate that the contractor did stop spraying the chemical in areas cited in the report. An update to the first report, published in […]

DuPont Pays $1.9 Million Penalty to EPA, Fails to Disclose Data on Pesticide Hazard

­ ­ ­(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 […]

GAO Report Questions Adequacy of EPA’s Conditional Pesticide Registration System

(Beyond Pesticides, September 11, 2013) In a report released Monday, the Government Accountability Office (GAO) finds that the U.S. Environmental Protection Agency (EPA)’s use and oversight of conditional registrations is lacking and unreliable. Conditional registration allows pesticides onto the consumer market without all the required data to assess the chemical’s safety. This has created many serious human and environmental health problems, including bee decline, tree death and potential increases in human health risks. GAO recommends that EPA better track conditional registrations, however, Beyond Pesticides and other concerned groups urge the agency to cancel registrations until all relevant data is submitted and reviewed. According to the findings of the GAO’s report, EPA’s system for tracking pesticides with conditional registration is unreliable and thus, the total number of conditional registrations granted is unclear.   This lack of a reliable system for managing conditional registrations constitutes an ”˜internal control weakness’ because the agency lacks an effective mechanism for program oversight and decision making, according to federal internal control standards cited by GAO. The report states, “The extent to which EPA ensures that companies submit additional required data and EPA reviews these data is unknown. Specifically, EPA does not have a reliable system, such […]

DuPont’s Liability for Toxic Herbicide Mounting

(Beyond Pesticides, July 6, 2012) The agribusiness conglomerate DuPont has received more than 30,000 damage claims arising from its sale of a pesticide that resulted in death and injury to hundreds of thousands of evergreen trees, particularly Norway spruce and white pine. DuPont marketed the pesticide, sold under the trade name Imprelis, based on a conditional registration that the U.S. Environmental Protection Agency (EPA) granted in 2010. Soon after Imprelis became commercially available the next spring, EPA began receiving widespread reports of tree death and injury from landscapers and residential users who had applied the pesticide according to its label conditions. EPA issued an immediate stop sale order for Imprelis on August 11, 2011 after DuPont submitted reports of more than 7,000 reports of tree damage. The New York Times reports that DuPont has set aside $225 million for claims that have already been submitted, and that the payout could ultimately reach $575 million. These figures do not include costs related to a class-action lawsuit filed by thousands of homeowners, landscapers and others, consolidated in federal court in Philadelphia. Some claimants are frustrated by the pace of the claims process and communications from the company. “We’re hearing nothing,” said Janet […]

DuPont To Issue Recall of Pesticide Linked to Tree Deaths

(Beyond Pesticides, August, 8, 2011) In a move that highlights serious concerns regarding the pesticide registration process, DuPont has announced that it plans to issue a total recall of its new herbicide, Imprelis, following widespread evidence and complaints that the product has caused the deaths of trees around the country. After originally giving conditional approval to the new pesticide, the U.S. Environmental Protection Agency (EPA) has now stated that it is preparing to issue a “Stop Sale” order to halt any further use of the product. According to a letter posted on DuPont’s website Imprelis-Facts.com, the company is implementing a “voluntary suspension” of Imprelis sales. It intends to ask distributors to collect all Imprelis containers, even those partially used, that they have sold and return them to the company for a refund. Earlier this year, in what some said was one of the biggest disasters of its kind since the emerald ash borer killed millions of trees, Imprelis was linked to white pine and Norway spruce trees turning brown or dying all across the country. Tree damage was reported throughout the Midwest, in East Coast states and as far south as Georgia. Many landscapers in Michigan and elsewhere switched to […]

New Lawn Chemical Suspected in Mysterious Deaths of Trees

(Beyond Pesticides, July 13, 2011) Millions of dollars’ worth of Norway spruce and white pine trees are mysteriously turning brown and dying this summer, and the chief suspect is a new lawn chemical. The product, Imprelis, a new herbicide manufactured by DuPont, is suspected by State officials and lawn care professionals who say they think Imprelis may be attacking pines and spruces. Once again, this new incident exposes the deficiencies in the registration process for new pesticides put onto the market without a full data set. In what some say could be one of the biggest disasters of its kind since the emerald ash borer killed millions of trees, white pine and Norway spruce trees are turning brown or dying all around the country. Tree damage has been reported throughout the Midwest, in East Coast states and as far south as Georgia. Many landscapers in Michigan and elsewhere switched to Imprelis (See the MSDS here) this year to control weeds such as dandelions because it was touted as “safer” by DuPont for the environment than predecessors such as 2, 4-D. So many trees have died -from the East Coast west to Iowa – that the damage is projected to be […]
