NOTES Participants: Tom Steeger, Katrina White, Kris Garber , and Marietta Escheverria (EPA/EFED), Christina Scheltema, Tom Moriarty, Tracy Perry, and Patty Parrott (EPA/PRD), Meredith Laws (EPA/RD), Mike Gorrell, Dave Fisher , and Lisa Ortego (Bayer CropScience ), and Jonathin Akins (TKI). Meeting Summary: The purpose of the meeting was to discu ss a registration review data requirement for a pollinator field study for carbaryl. Bayer CropSci ence, the carbaryl registrant of record, requested the meeting to better understand EPA’s rationalefor requiring the study. Bayer had previously conducted a field pollinator study for the Sevin XLR formulated product (to satisfy a Data Call-In for reregistration) and agreed to implement labeling to mitigate risk to bees as part of the reregistration process. Bayer gave a short presentation summarizing their perspective. This included a brief discussion of the recently developed risk assessment framework for pollinators, the existing label language for carbaryl, and existing pollinator field studies for carbaryl. This was followed by a discussion of EPA’s concerns for uses that were not addressed by the labeling as we ll as EPA’s data needs for registration review. The Agency is requiring additional data to fulfill the remaining data gaps and uncertainties regarding pollinator exposure to and risk from labeled uses of carbaryl. EPA staff clarified the rationale for the data requirement, as well as the specific data requirements for a larval study and a semi-field study on intact hives. EPA staff also clarified that the semi-field study should be conducted using a crop that is attractive to bees and is a good source of pollen and nectar 1

Although the current carbaryl labels prohibit application to plants during bloom, the semi-field study should beconducted with a crop in bloom to evaluate the effects of carbaryl to a hive under worst-case conditions. Bayer requested until February 15, 2013 to submit a testing proposal. EPA agreed, provided that protocols follow shortly thereafter.

# Carbaryl Bee Label Language Sevin XLR Plus, 4F

• BEE CAUTION: This product is highly toxic to honeybees and other bees exposed to direct treatment or residues on crops or weeds in bloom. This product may show residual toxicity to honeybees, especially in humid climates or under slow drying conditions. Notifying beekeepers within 1 mile of treatment and at least 48 hours before product is applied will allow them to take additional steps to protect their bees. limiting application to times when bees are least active, e.g., within 2 hours of sunrise or sunset, will minimize risk to bees • For crops in bloom (except soybean and corn): Do not apply this product to target crops or weeds in bloom. • For soybean and corn: If application cannot be avoided when target crops or weeds are in bloom, limiting applications to times when bees are least active, e.g., within 2 hours of sunrise or sunset, will minimize risk to bees
