Bacillus thuringiensis var. buibui - Small-Scale Field Testing of a Non-indigenous Microbial Pesticide 8/94

[OPP-50800; FRL-4906-7]
Receipt of a Notification to Conduct Small-Scale Field Testing
of a Non-indigenous Microbial Pesticide
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.
------------------------------------------------------------
SUMMARY: EPA has received from Mycogen Corporation of San Diego,
California a notification (53219-NMP-R) of intent to conduct
a small-scale field testing of a non-indigenous microbial pesticide.
The Agency has determined that the application may be of regional
and national significance. Therefore, in accordance with 40
CFR 172.11(a), the Agency is soliciting public comments on this
application.

DATES: Written comments must be received on or before September
30, 1994.

ADDRESSES: Comments in triplicate, must bear the docket control
number OPP-50800 and be submitted to: Public Docket and Freedom
of Information Section, Field Operations Division (7506C), Office
of Pesticide Programs, Environmental Protection Agency, 401
M St., SW., Washington, DC 20460. In person bring comments to:
Rm. 246, CM #2, 1921 Jefferson Davis Highway, Arlington, VA.

   Information submitted in any comment(s) concerning this notice
may be claimed confidential by marking any part or all of that
information as "Confidential Business Information" (CBI).
Information so marked, will not be disclosed except in accordance
with procedures set forth in 40 CFR part 2. A copy of the comment(s)
that does not contain CBI must be submitted for inclusion in
the public record. Information not marked confidential may be
disclosed publicly by EPA without prior notice to the submitter.
Information on the proposed test and all written comments will
be available for public inspection in Rm. 246 at the Virginia

FOR FURTHER INFORMATION CONTACT: By mail: Phil Hutton, Product
Manager (PM) 18, Registration Division (7505C), Office of Pesticide
Programs, Environmental Protection Agency, 401 M St., SW., Washington,
DC 20460. Office location and telephone number: Rm. 213, CM
#2, 1921 Jefferson Davis Highway, Arlington, VA (703-305-7690).

SUPPLEMENTARY INFORMATION: A notification of intent to conduct
small-scale field testing pursuant to EPA's Statement of Policy
entitled, "Microbial Products Subject to the Federal Insecticide,
Fungicide, and Rodenticide Act and the Toxic Substances Control
Act," published in the Federal Register of June 26, 1986 (51
FR 23313), has been received from Mycogen Corporation of San
Diego, California (53219-NMP-R). The proposed small-scale field
trial involves the release of a non-indigenous microbial pesticide
Bacillus thuringiensis serovar japonensis strain Buibui (B.t.
buibui) into the field in order to evaluate the efficacy of
this microbial pesticide against certain Coleopteran pests for
the control of white grubs in turfgrass relative to the commercially
available pesticides.

   Field trials will be classified as small or micro-plot studies
and will be conducted within areas of approximately 50 ft. by
100 ft. Treatments will include three to five replicates per
treatment. Testing will consist of one or two applications which
coincide with specific stages of larval development, 1st, 2nd,
and 3rd larval instars.
   Field trials will be conducted using prototype liquid flowable
formulations and some limited testing with dry granular formulations.
Liquid treatments will be applied to plots in the test area
using a handheld compressed air sprayer with nozzles. Granular
formulations will be applied using a pre-calibrated drop spreader.
The proposed field trials will be conducted during July - September
1994 and monitored 21 days following initial application. Following
the review of American Cyanamid Company's application and any
comments received in response to this notice, EPA will decide
whether or not an experimental use permit is required.

   Dated: August 19, 1994.

Stephen L. Johnson,
Director, Registration Division, Office of Pesticide Programs.
