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,

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.

Director, Registration Division, Office of Pesticide Programs.
