Dear Harold,

Thank you for allowing comment on the proposed napropamide mitigation measures.

There are some errors in the letter regarding the percent of acres treated with napropamide in California. Several listed crops do have more than 5% of the total acres treated. This indicates needed uses and these should not be deleted from the label. In California the following crops use napropamide on more than 5% of the acres: Basil, Blackberry, Blueberry and Persimmon. This information was obtained from the California Pesticide Use Report for 2003 (the most recent year available).

The recommended use rates do not appear to pose a problem, as they are not exceeded in the reported use.

Sincerely,

Rick

Subject: Mitigation Proposal/Napropamide

Here is EPA's mitigation proposal on napropamide. If anyone has any concerns, let me know. Looks OK from my perspective based on what I have heard from out in the field.
