Dear Ms. Burgwin:
Re: Registration of the New Active Ingredient Ampelomyces quisqualis
Isolate M10; Contained in the Pesticide Product AQ10 Biofungicide
(EPA Reg. No. 55638-16)
Ecogen Inc. applied for New York State registration for AQ10
Biofungicide (EPA Reg. No. 55638-16) which contains the new active
ingredient Ampelomyces quisqualis Isolate M10.
AQ10 Biofungicide is a fungus that parasitizes powdery mildew.
Following rehydration and application, AQ10 spores germinate into the
powdery mildew mycelia and parasitize it. AQ10 Biofungicide is for use
to control powdery mildew on the following field and greenhouse crops:
apples, cucurbits, grapes, ornamentals, strawberries and tomatoes. The
application rate is 1 oz./acre, which is equal to 0.036 lb. active
ingredient/acre, or 1.4 x 1011 viable spores/acre. The estimated
maximum number of applications is 12 per season or 0.43 lb. active
ingredient/acre per season.
The New York State Department of Environmental Conservation (the
Department) has completed the review of the information supplied to date
in support of the pesticide product registration application for AQ10
Biofungicide, which contains the new active ingredient Ampelomyces
quisqualis Isolate M10.
Ampelomyces quisqualis Isolate M10 is a naturally occurring biological
pesticide and the United States Environmental Protection Agency (EPA)
required only limited toxicological and non-target organism data. The
EPA waived all other data requirements for this product, including
chronic mammal and avian, freshwater fish, marine/estuarine, aquatic
plant, and environmental fate studies, due to its nontoxic nature and
target specificity. The EPA did not require data on crop residues and
determined that establishment of a tolerance for food crops is not
necessary to protect the public health from AQ10 Biofungicide use.
Ampelomyces quisqualis Isolate M10 does not appear to be very toxic or
pathogenic in laboratory animals. There have been no reported cases of
adverse reactions associated with the production or use of AQ10
Biofungicide. The uses specified on the AQ10 Biofungicide product label
should neitner significantly increase exposure of the general population
to Ampelomyces quisqualis Isolate M10 nor pose risks to workers adhering
to the personal protection equipment requirements and recommendations.
Therefore, the Department hereby accepts AQ10 Biofungicide (EPA Reg. No.
55638-16) for registration.
Enclosed are your New York State stamped "ACCEPTED" label and a copy of
the Certificate of Registration.
Please contact Ms. Maureen Serafini, of my staff, at (518) 457-7446, if
you have any questions.
