This just in from the Oregon Department of Ag: ODA is temporarily restricting the use of 18 pesticides containing dinotefuran while it investigates the death of thousands of bees near Portland this month. Dinotefuran is a neonicontinoid, a class of pesticides that have been linked to honeybee die-offs.
In the wake of large bee kills, ODA takes steps in an abundance of caution
ODA restricts use of certain dinotefuran pesticides
June 27, 2013… The Oregon Department of Agriculture is restricting the use of 18 pesticide products containing the active ingredient dinotefuran while it continues the investigation of a large kill of bumblebees in Wilsonville and Hillsboro this month. By adopting a temporary rule, ODA is taking action, in an abundance of caution, to avoid the potential of similar large bee kills this summer due to specific pesticide applications.
“I have directed the agency to take this step in an effort to minimize any potential for additional incidents involving bee deaths connected to pesticide products with this active ingredient until such time as our investigation is completed and we have more information,” says ODA Director Katy Coba. “Conclusions from the investigation will help us and our partners evaluate whether additional steps need to be considered.”
The ODA restriction focuses on ornamental, turf, and agricultural pesticide products that are used by both professional applicators and homeowners. Products with the active ingredient dinotefuran registered in Oregon for other uses, such as flea and tick control on pets or home ant and roach control, are not affected by the restriction. ODA’s concern is focused on those uses that may impact pollinators.
By statute, ODA has legal authority to establish limitations and procedures deemed necessary and proper for the protection of bees and other pollinating insects. The temporary rule, which goes into effect immediately, will be enforced for 180 days, by which time ODA is expected to complete its pesticide use investigations of the Wilsonville and Hillsboro incidents. Those investigations will determine if the pesticide applications were in violation of state and federal pesticide regulations, and will assist ODA in addressing any potential future actions.
ODA’s Pesticide Program has established a website with more information on the dinotefuran restriction, including a list of specific products affected as well as instructions for those who may have purchased these products. Go to <http://oregon.gov/ODA/PEST/Pages/Pollinator.aspx>.
