Good Day!

EPA is looking at considering mitigation measures for mancozeb. For workers (applicators/handlers), they are considering the use of PPE (single layer and PF 5 respirator) for most crops. This is an improvement to the current double layer required on the label. For turf, they may require the use of water soluble packs and for seed treatments a closed capture system for dust formulations.

The current Re-Entry Interval (REI) is 24 hours for all crops. For most crops, they are proposing a change, for others they need your feedback to understand the cultural practices relative to mancozeb application.

Listed below are the suggested REIs, and questions, for each crop. If a crop is not listed, the REI will not be changed. Please let me know if there are activities growers need to do that this REI would inhibit.

Proposed REIs:

Let me know if you have any questions.
