To protect bees and other pollinators from outdoor foliar applications, the US EPA
has enacted new pesticide label language for four insecticides. According to EPA,
multiple factors play a role in bee colony declines, including pesticides.
The four nitroguanidine neonicotinoid insecticides are: imidacloprid, dinotefuran,
clothianidin and thiamethoxam. Several hundred pesticide labels will be revised in the
next coming months. To determine which products contain these active ingredients,
go to PICOL, http://cru66.cahe.wsu.edu/labels/Labels.php
The new label language will include specifically tailored use restrictions for:
•CROPS UNDER CONTRACTED POLLINATION SERVICES
•FOOD CROPS AND COMMERCIALLY GROWN ORNAMENTALSNOT UNDER CONTRACT FOR POLLINATION SERVICES BUT AREATTRACTIVE TO POLLINATORS
Labels for products containing dinotefuran* and clothianidin will have an additional
pollinator protection statement to protect managed honey bees post-application.
In addition to the new restrictions, the new labels will have a Bee Advisory Box and
icon with information on routes of exposure and spray drift precautions.
On Feb. 1, 2014, all product produced must bear the new labeling. Previously labeled
product can continue to be sold by pesticide dealers and used by applicators until
supplies are exhausted. Note to Pesticide Users - Follow the label directions on the
container in your possession.

Future: EPA is working with USDA and other partners to promote Best Management
Practices for growers, professional applicators and beekeepers. EPA is also reviewing
the most current data and determining additional ways to reduce risks to pollinations.
They are considering the various application methods (soil drench etc.), and types
of exposure (for example systemic).
* Currently the use of dinotefuran is prohibited for use on plants. For more
