Dear Audrey Sehn:
The U.S. Environmental Protection Agency is in receipt of your application for notification under Pesticide
Registration Notice 98-10 for the above referenced product. The EPA has conducted a review of this request
for its applicability under PRN 98-10 and finds that the action requested falls within the scope of PRN 98-10.
The labeling submitted with this application has been stamped "Notification" and will be placed in our records.
Should you wish to add/retain a reference to your company’s website on your label, then please be aware that
the website becomes labeling under the Federal Insecticide, Fungicide, and Rodenticide Act and is subject to
review by the EPA. If the website is false or misleading, the product will be considered to be misbranded and
sale or distribution of the product is unlawful under FIFRA section 12(a)(1)(E). 40 CFR § 156.10(a)(5) lists
examples of statements the EPA may consider false or misleading. In addition, regardless of whether a
website is referenced on your product’s label, claims made on the website may not substantially differ from
those claims approved through the registration process. Therefore, should the EPA find or if it is brought to
our attention that a website contains statements or claims substantially differing from statements or claims
made in connection with obtaining a FIFRA section 3 registration, the website will be referred to the EPA’s
Office of Enforcement and Compliance Assurance.
If you have questions, please contact Senedu Alemu via email at alemu.senedu@epa.gov.
