The following request came in from EPA. Let me know of any niche (important but less than 5%) uses for napropamide (Devrinol) in your areas.

Thanks.

Hi, Harold:

BEAD is currently conducting a benefits analysis for napropamide where intend to target the uses with the highest percent crop treated (strawberries, tomatoes, peppers, tobacco, artichokes, and eggplant - % crop treated ranges from 10 - 20%). We wanted to also get an idea of the benefits for crops that are not in that group. For those commodities that are 5% crop treated or less, we would like to know if you are aware of any niches for these uses? There are a number of crops that fall into that category.

BEAD has also identified that there could be significant use for ornamentals for some crop/state combinations (for example, nursery grown azaleas and rhododendrons in Washington and ornamental grasses in Michigan). If you could provide some information concerning these issues, we would really appreciate it. If you could expedite this information to us at your earliest convenience, it would be helpful. Let me know if you have any questions. Thanks for your help.
