Summary
The EPA issued a data call-in requiring registrants of pendimethalin pesticide products to submit Endocrine Disruptor Screening Program (EDSP) studies. Affected parties must provide specific toxicology and exposure data to support EPA's evaluation of potential endocrine-disrupting effects.

What changed
The EPA has issued a data call-in under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) requiring registrants of pendimethalin-containing pesticide products to generate and submit Endocrine Disruptor Screening Program studies. This mandate obligates registrants to conduct and submit specific toxicology data to support EPA's ongoing review of potential endocrine-disrupting effects of pendimethalin.
Registrants with pendimethalin products face immediate compliance obligations to initiate required studies and submit data within EPA's specified timeline. Failure to respond to this data call-in may result in EPA initiating registration review procedures, including potential suspension or cancellation of affected product registrations. Companies should review their pendimethalin product portfolios and allocate resources for required EDSP study generation.
What to do next
- Submit required EDSP studies to EPA by the specified deadline
- Review all pendimethalin product registrations for affected data requirements
- Contact EPA if unable to meet data submission timeline
Penalties
Registration suspension or cancellation for failure to comply with data call-in requirements
