According to OPB, Oregon is the first state to take steps to limit neonicotinoid pesticides related to bee die-offs.
The restrictions apply to the pesticide ingredients dinotefuran and imidicloprid. Officials say they believe those ingredients – when sprayed on trees that have their own natural toxicity – become fatally toxic to bees and other pollinators.
To prevent more bee kills, Oregon is prohibiting the use of products containing those two ingredients on linden trees, basswood and other Tilia species that have similar natural toxins. The products will have to be labeled with the restriction before they can be sold in Oregon.
