I. INTRODUCTION 

The Food Quality Protection Act (FQPA) of 1996, mandated a registration review program. 

All pesticides distributed or sold in the United States (U.S.) generally must be registered by the 

Environmental Protection Agency (EPA or the Agency), based on scientific data showing that 

they will not cause unreasonable risks to human health or the environment when used as directed 

on product labeling. The registration review program is intended to make sure that, as the ability 

to assess risk evolves and as policies and practices change, all registered pesticides continue to 

meet the statutory standard of no unreasonable adverse effects to human health or the 

environment. Changes in science, public policy, and pesticide use practices will occur over time. 

Through the registration review program, the Agency periodically reevaluates pesticides to make 

sure that as change occurs, products in the marketplace can be safely used. Information on this 

program is provided on EPA’s website.1

In 2006, the Agency implemented the Registration Review program pursuant to FIFRA 

Section 3(g), and will review each registered pesticide every 15 years to determine whether it 

continues to meet the FIFRA standard for registration. 

Pursuant to 40 CFR §155.50, the Agency formally initiated registration review for 

tebufenpyrad (case 7435) in September 2014. The following timeline highlights significant 

events that have occurred regarding the registration review of tebufenpyrad: 

 April 8, 2014 – The sole registrant of tebufenpyrad products, Nichino America, Inc., 

informed the Agency that it was requesting to voluntarily cancel all tebufenpyrad product 

registrations (EPA Reg. Nos. 71711-22, technical formulation, and 71711-23, end use 

formulation). 

 August 6, 2014 – Publication announcing receipt of the request to voluntarily cancel all 

of Nichino America, Inc. tebufenpyrad product registrations in the Federal Register (79 

FR 45803, FRL-9914-36). No comments were received during the 30-day public 

comment period. 

 September 24, 2014 – Publication of a final Cancellation Order for all tebufenpyrad 

product registrations in the Federal Register (79 FR 57087, FRL-9916-69). 

 September 24, 2014 – Publication of the Tebufenpyrad Preliminary Work Plan in the 

tebufenpyrad docket (EPA-HQ-OPP-2014-0218) for a 60-day public comment period. 

No comments were received.

psylla, serpentine leafminer, thrips, and whiteflies. Tebufenpyrad is not currently manufactured 

for use. All registrations for tebufenpyrad have been canceled as discussed below. 

Prior to initiation of the registration review for tebufenpyrad, the sole registrant of 

tebufenpyrad products, Nichino America, Inc., informed the Agency that it was intending to 

request voluntarily cancellation of all of its tebufenpyrad product registrations (EPA Reg. Nos. 

71711-22, technical formulation, and 71711-23, end use formulation). On April 8, 2014, 

Nichino America, Inc., submitted a letter requesting voluntary cancellation of all of their 

products containing the active ingredient tebufenpyrad and waiving the 180-day public comment 

period in lieu of a 30-day public comment period under FIFRA Section 6(f). 

On August 6, 2014, the Agency issued a Notice of Receipt of Requests to Voluntarily Cancel 

Nichino America, Inc.’s technical and end-use product registrations. The notice initiated a 30-

day public comment period during which the Agency received no comments. After the close of 

the public comment period, the Agency issued a Final Cancellation Order on September 24, 

2014 cancelling all tebufenpyrad product registrations (copies of those notices are included in the 

docket for this registration review) effective on September 24, 2014. EPA Reg. Nos. 71711-22 

and 71711-23 were the last tebufenpyrad pesticide product registrations in the United States. 

The existing stocks provisions for these products are as follows: The registrant may continue 

to sell and distribute existing stocks until September 24, 2015, which is one year after the 

publication of the cancellation order. Thereafter, the registrant is prohibited from selling or 

distributing the products except for export in accordance with FIFRA section 17, or for proper 

disposal. Persons other than the registrant may sell, distribute, or use existing stocks of products 

until existing stocks are exhausted, provided that such sale, distribution, or use is consistent with 

the terms of the previously approved labeling on, or that accompanied, the canceled products. 

III. REGISTRATION REVIEW CASE CLOSURE 

As stated in the Tebufenpyrad Preliminary Work Plan, the Agency anticipated closing the 

registration review case for tebufenpyrad once all tebufenpyrad product registrations were 

cancelled. A cancellation order issued on September 24, 2014, canceled all tebufenpyrad 

product registrations in the United States. In view of the cancellation order, the Agency is 

closing the registration review case for tebufenpyrad pursuant to 40 CFR §155.42(c) which 

provides that the Agency “will close a registration review case if all products in the case are 

canceled.” This document concludes the tebufenpyrad registration review case.
