Regulatory Issues

Update

The Oregon Department of Agriculture (ODA) held a public hearing on January 21, 2015, regarding a proposed new rule. The rule, as proposed, would prohibit the application of any product containing dinotefuran, imidacloprid, thiamethoxam, or clothianidin, regardless of application method, to linden trees, basswood trees or other Tilia species. 

Comments were accepted on the proposed new rule from December 12, 2014, until
5 p.m. January 21, 2015. These comments were carefully reviewed and considered by ODA. Some of the commenters suggested that ODA should only prohibit the use of dinotefuran and imidacloprid, and not also prohibit the use thiamethoxam and clothianidin on linden trees.

After much deliberation, the department decided to prohibit the application of any product containing dinotefuran, imidacloprid, thiamethoxam, or clothianidin, regardless of application method, to linden trees, basswood trees or other Tilia species.

The permanent rule (OAR 603-057-0388) went into effect on February 27, 2015. The rule supersedes label language. This means that even if a pesticide user has a pesticide label which provides directions for use on linden trees, ornamental trees (or a similar site), the product can not be used on linden trees, basswood trees or other Tilia species in the State of Oregon.

Pollinators

Pollinators are extremely important to Oregon's agricultural community, pollinating many crops. Oregon is proactive in protecting bees and other pollinators and currently requires specific label language prohibiting the use of the neonicotinoid pesticides, dinotefuran and imidacloprid, on linden, basswood and Tilia species trees.

At the federal level, the Environmental Protection Agency (EPA) has required special label restrictions to neonicotinoid pesticides in order to protect pollinators. The active ingredients that will have special label language are as follows:

  • Clothianidin
  • Dinotefuran
  • Imidacloprid
  • Thiamethoxam
