SUPPLEMENTARY INFORMATION:
I. General information
A. Does this action apply to me?
You may be potentially affected by this action if you are an
agricultural producer, food manufacturer, or pesticide manufacturer.
The following list of North American Industrial Classification System
(NAICS) codes is not intended to be exhaustive but rather provides a
guide to help readers determine whether this document applies to them.
Potentially affected entities may include:
<bullet> Crop production (NAICS code 111).
<bullet> Animal production (NAICS code 112).
<bullet> Food manufacturing (NAICS code 311).
<bullet> Pesticide manufacturing (NAICS code 32532).
If you have any questions regarding the applicability of this
proposed action to a particular entity, consult the person listed under
FOR FURTHER INFORMATION CONTACT.
B. What should I consider as I prepare my comments for EPA?
1. Submitting CBI. Do not submit CBI to EPA through email or
<a href="https://www.regulations.gov">https://www.regulations.gov</a>. If you wish to include CBI in your
comment, please follow the applicable instructions at <a href="https://www.epa.gov/dockets/commenting-epa-dockets#rules">https://www.epa.gov/dockets/commenting-epa-dockets#rules</a> and clearly mark the
information that you claim to be CBI. Information so marked will not be
disclosed except in accordance with procedures set forth in 40 CFR part
2.
C. What is EPA's authority for taking this action?
Under section 18 of the Federal Insecticide, Fungicide, and
Rodenticide Act (FIFRA) (7 U.S.C. 136p), at the discretion of the EPA
Administrator, a Federal or State agency may be exempted from any
provision of FIFRA if the EPA Administrator determines that emergency
conditions exist which require the exemption. EPA implementing
regulations are set forth in 40 CFR part 166.
II. What action is the Agency taking?
EPA is announcing receipt of requests submitted to EPA under FIFRA
section 18. This notice does not constitute a decision by EPA on the
application itself. The regulations governing FIFRA section 18 require
publication of a notice of receipt of an application for a specific
exemption proposing use of a new chemical (i.e., an active ingredient)
which has not been registered by EPA.
II. Summary of the Request Received
The Arkansas and Missouri Departments of Agriculture have requested
the EPA Administrator to issue specific exemptions for the use of
tetflupyrolimet on rice to control Barnyardgrass resistant to multiple
herbicides. Information in accordance with 40 CFR part 166 was
submitted as part of this request. As part of this request, the
applicants assert that emergency conditions exist due to insufficient
means to control Barnyardgrass resistant to rice herbicides, especially
Barnyardgrass resistant to multiple herbicides, which leaves rice
growers without an effective control option. The use of tetflupyrolimet
will help avert significant economic losses.
The Applicants propose to make up to two applications of 8.6 fluid
ounces of the unregistered product, KEENALI HERBICIDE (containing 35.0%
tetflupyrolimet, equivalent to 3.34 lbs. of tetflupyrolimet per gallon
of product) on up to a total of 646,000 acres of rice (546,000 in
Arkansas and 100,000 in Missouri), from March 1, 2026 to July 1, 2026.
If a maximum of two applications are made to the maximum requested
acreage, a potential of 43,399 gallons of product (equivalent to
146,080 pounds of tetflupyrolimet) could be used.
The Agency will review and consider all comments received during
the comment period in determining whether to issue the specific
exemptions requested by the Arkansas and Missouri Departments of
Agriculture.
Authority: 7 U.S.C. 136 et seq.
Dated: February 2, 2026.
Charles Smith,
Director, Registration Division, Office of Pesticide Programs.
