According to the Oregon Department of Agriculture (ODA), the state 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 a report entitled “In the wake of large bee kills, ODA takes steps in an abundance of caution,” we find that the ODA restricts use of certain dinotefuran pesticides. They are 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.”
