Reminder of mandatory no spray zones

Dear Watershed Councils:

As spray season gets underway, we are writing with a request that you notify your contacts about the mandatory no-spray zones along salmon-supporting waters in Oregon, Washington, and California.

The attached graphic files are designed for quick reference, and are a reminder that these buffers are required specifically for salmon and steelhead protection. No-spray buffers along designated salmon-bearing waterways in Washington, Oregon and California are currently required to be 60 feet for ground applications, and 300 feet for aerial applications of pesticides containing any of the following active ingredients (some common trade names are shown in parentheses):


bromoxynil     (Buctril, Maestro, Moxy)

carbaryl         (Sevin, Duocide, Liquid Fruit Tree Spray)

chlorpyrifos    (Dursban, Lorsban, Nufos)

diazinon         (Diazinon)

malathion       (Fyfanon, Malathion)

methomyl       (Annihilate, Corrida, Lannate)

metolachlor    (Bicep, Cinch, Dual, Me-Too-Lachlor, Parallel)

prometryn      (Caperol, Vegetable Pro)

1,3-dichloropropene    (Telone, 1,3-D)


The attached pdf has live links that get people to the EPA Salmon Mapper site ( which helps identify exactly where the buffers apply. Links to the state pesticide regulatory agencies are also provided.


These no-spray zones will remain in place for carbaryl, chlorpyrifos, diazinon, malathion, and methomyl until EPA implements any necessary protections for Pacific salmon and steelhead based on reinitiated consultations with the National Marine Fisheries Services.  Buffer zones for the remaining four chemicals will remain in place until final Biological Opinions are completed by National Marine Fisheries Service.


We appreciate your help in distributing this information to your contacts. Posting this information on your website, as well as distributing by email, Facebook, Twitter, or newsletter would all be great ways to get the reminder out. We’re attaching the graphic as a jpg file, as well as pdf.


Thank you for your assistance. Please contact us or your state pesticide regulatory agency with any questions.
