SUMMARY: EPA has received a specific exemption request from the Arizona
Department of Agriculture (hereafter referred to as the ``Applicant'')
for use of the pesticide, bifenthrin (Capture), to control sweetpotato
whitefly (SWF) on up to 5,500 acres of leaf lettuce and 6,100 acres of
cauliflower in Arizona. In accordance with 40 CFR 166.24, EPA is
soliciting public comment before making the decision whether or not to
grant the exemption.
DATES: Comments must be received on or before September 14, 1995.

SUPPLEMENTARY INFORMATION: Pursuant to section 18 of the Federal
Insecticide, Fungicide, and Rodenticide Act (FIFRA) (7 U.S.C. 136p),
the Administrator may, at her discretion, exempt a State agency from
any registration provision of FIFRA if she determines that emergency
conditions exist which require such exemption. The Applicant has
requested the Administrator to issue a specific exemption for use of
the bifenthrin, available as Capture 2EC from FMC Corporation, to
control sweetpotato whitefly on up to 5,500 acres of leaf lettuce and
6,100 acres of cauliflower per season in Arizona. Information in
accordance with 40 CFR part 166 was submitted as part of this request.
According to the Applicant, the lack of hard freezes during the
past winter
[[Page 45160]]
has allowed a large number of whiteflies to survive. Although
imidacloprid was recently registered as an alternative to control the
SWF, a single soil application of imidacloprid will not adequately
protect the crop throughout the full production cycle. Imidacloprid is
systemic and can be taken up by the seedling as it emerges through the
soil, and will have minimal impact on beneficial predators and
parasites of the whitefly. Foliar application will be needed to provide
additional control of whiteflies later in the season. It might be
possible to utilize imidacloprid for these foliar applications, but its
mode of action is such that development of resistance is a major
concern. The mode of action of this product depends on its ability to
interact with a specific neuroreceptor of the pest. Should pest
populations develop in which this neuroreceptor is altered, resistance
would result. Bayer is well aware of this fact and will not support
continued use of their product later into the vegetable growing season.
The Applicant believes the use of bifenthrin as a foliar spray in
combination with imidacloprid at planting will provide excellent
control of whiteflies. Without the use of bifenthrin, the Applicant
claims that growers will suffer significant economic loss this growing
season.
Under the proposed exemption, a maximum of four applications per
crop season for lettuce, and a maximum of 5 applications per crop
season for cauliflower would be made at [0.08 to 0.1 lb of active
ingredient (a.i./A)] (5.2 to 6.4 fl. ozs. of product per acre) by
ground or air equipment. Not to apply within 20 days of harvest. Do not
apply by ground equipment within 25 feet or by air within 150 feet of
lakes, reservoirs, rivers, permanent streams or natural ponds estuaries
and commercial fish farms. A 200-yard buffer shall be observed around
aquatic habitats containing endangered species (desert pupfish,
woundfin and Gila topminnow).
This notice does not constitute a decision by EPA on the
application itself. The regulations governing section 18 require that
the Agency publish notice of receipt in the Federal Register and
solicit public comment on an application for a specific exemption if an
emergency exemption has been requested or granted for that use in any 3
previous years, and a complete application for registration of that use
has not been submitted to the Agency [40 CFR 166.24(a)(6). Exemptions
for the use of bifenthrin on lettuce have been requested and granted
for the past 3 years, and an application for registration of this use
has not been submitted to the Agency.
A record has been established for this notice under docket number
``[OPP-180979]'' (including comments and data submitted electronically
as described below). A public version of this record, including
printed, paper versions of electronic comments, which does not include
any information claimed as CBI, is available for inspection from 8 a.m.
to 4:30 p.m., Monday through Friday, excluding legal holidays. The
public record is located in Room 1132 of the Public Response and
Program Resources Branch, Field Operations Division (7506C), Office of
Pesticide Programs, Environmental Protection Agency, Crystal Mall #2,
1921 Jefferson Davis Highway, Arlington, VA.
Electronic comments can be sent directly to EPA at:
opp-docket@epamail.epa.gov
Electronic comments must be submitted as an ASCII file avoiding the
use of special characters and any form of encryption.
The official record for this notice, as well as the public version,
as described above will be kept in paper form. Accordingly, EPA will
transfer all comments received electronically into printed, paper form
as they are received and will place the paper copies in the official
record which will also include all comments submitted directly in
writing. The official record is the paper record maintained at the
address in ``ADDRESSES'' at the beginning of this document.
Accordingly, interested persons may submit written views on this
subject to the Field Operations Division at the address above. The
Agency will review and consider all comments received during the
comment period in determining whether to issue the emergency exemption
requested by the Arizona Department of Agriculture.
