INTRODUCTION 

The purpose of this document is to convey usage information and a broad overview of the pest 

management roles of pesticides that are beginning to undergo registration review. The 

anticipated audience consists of the team of EPA staff currently evaluating the registration status 

of tebufenpyrad, and eventually the general public. This document builds upon the data already 

1 
provided in the LUIS label report that is also provided to Registration Review teams by BEAD. 

The document is based on information and data available to BEAD as of March 27, 2014. 

Tebufenpyrad is a miticide/insecticide for use on non-edible ornamental plants grown in 

commercial greenhouses. It targets some mites, aphids, whiteflies, and mealybugs. There is no 

evidence that this product has been marketed in the United States. 

COMMON FORMULATIONS AND APPLICATION METHODS 

It is registered as an emulsifiable concentrate. It may be applied with hydraulic, backpack, 

compressed air, low volume, electrostatic, and other types of sprayers. 

USAGE 

There are no reported usage data for this chemical in proprietary or California Department of 

Pesticide Regulation databases. 

HISTORY OF TEBUFENPYRAD and BEAD PRODUCTS 

Tebufenpyrad (Trade Names: MasaiTM, PyranicaTM, PestanalTM,) is an insecticide registered for 

use in the United States in 2002 and in the U.K., Australia and Japan primarily as an Acaricide. 

There are no records of prior BEAD benefit assessments or reviews of emergency exemption 

requests for tebufenpyrad. 

DATA NEEDS RELEVANT TO BEAD'S FUTURE WORK ON TEBUFENPYRAD 

Obtaining information on the following items would improve future BEAD assessments of the 

importance of tebufenpyrad and may be required as part of the registration review of this 

pesticide. Should the registrant decide to manufacture this product for sale in the United States, 

It would be helpful for BEAD to know the amount of chemical expected to be used or being used 

in commercial greenhouses, the application rate, the number of applications, the percent crop 

treated, the total amount applied, the geographic locations of the greenhouses (states where it is 

used), the specific pests targeted, and the specific agricultural and horticultural sites 

(ornamentals) to which it is being applied.
