Dear Ms. Phoenix:
RE: Cancellation of Registration for DeltaGard G Insecticide Granules (EPA Reg. No. 432-824) in New York State
This letter is to advise you that the New York State Department of Environmental Conservation
(Department) is canceling the registration of the above-referenced pesticide product in New York State, effective 30
calendar days from the date of service of this notification. This registration is being canceled due to a
misclassification of the application type, resulting in the product being registered by the Department in error.
Consequently, the material required to be submitted, at the time of application, did not comply with the provisions of
New York State Environmental Conservation Law (ECL) Article 33 and the implementing standards.
DeltaGard G Insecticide Granules (EPA Reg. No. 432-824) is labeled for outdoor use on the home lawn and
around other residential buildings. It contains the active ingredient deltamethrin. The active ingredient deltamethrin
was previously evaluated by this Department in the products RUC 161 Insecticide (EPA Reg. No. 432-763) and DeltaTech
(EPA Reg. No. 432-762). RUC 161 Insecticide is labeled to control insect pests in and around residential, industrial
and institutional structures and their immediate surroundings and on various modes of transportation. DeltaTech is
labeled for formulation into insecticides for these uses. As a result of our technical review, we concluded that the
use pattern for RUC 161 as an outside perimeter treatment did not pose a significant threat to human health and
environmental resources in New York State. Both products were registered in New York State on August 5, 1996 (reference
letter from N. Nosenchuck to J. Stern dated August 5, 1996, enclosed).
The application to register a new routine product, DeltaGard G Insecticide Granules, was received on
October 24, 1996. However, the application was improperly identified as an initial registration type (I.B.1) and as a
result, the product was inadvertently accepted for registration on October 30, 1996. DeltaGard G Insecticide Granules
expands the perimeter treatment use of deltamethrin to use on home lawns and should have been identified as a major
change in labeling. The application for DeltaGard G Insecticide Granules was not identified by AgrEvo as a major change
in use pattern and no supporting data was submitted with the application. Section II(A)(2) of the "New York State
Pesticide Product Registration Procedures" handbook
(August 1996 - copy enclosed) states that applications must be clearly identified by the applicant as to the
registration type. Because the application was misidentified, the evaluation required for an application constituting a
major change in labeling was not conducted.
Pursuant to our letter dated August S, 1996, the Department informed AgrEvo that any additional uses for
deltamethrin, at or above the maximum application rate for
RUC 161, would have to be reviewed and supported by additional data. Based upon our initial evaluation, the Department
was concerned about potential toxicity to fish, invertebrates and mammals from use of deltamethrin in outdoor settings
beyond the approved perimeter treatments. Data was suggested which could be submitted to address the Department's
concerns if AgrEvo intended to apply for expanded outdoor uses for deltamethrin.
AgrEvo agreed to the destruction of the data package submitted to support the registration of RUC 161. In
a letter dated August 26, 1996 (copy enclosed), the Department confirmed that the data had been destroyed, per AgrEvo's
concurrence, because there was, and is ently, no capacity to store inactive data packages.
The Department did not evaluate the use of deltamethrin on home lawns under the previously-submitted
application for RUC 161 as it was not a proposed use in that application. It is our procedure to evaluate only the
use(s) proposed on the product label submitted with an application. Any changes or additions to the general use pattem
which is currently registered for the active ingredient must be reviewed separately pursuant to a separate application
identifying the change as a major change in use pattern for the active ingredient in New York State.
The use of deltamethrin on home lawns must be evaluated by this Department for potential risks to human
health and environmental resources in New York State. Deltamethrin is potentially toxic, on an acute and chronic basis,
to fish and invertebrate in both fresh and saltwater, and may be toxic to small mammals. RUC 161 was determined not to
pose significant risks to fish and wildlife resources in New York State because of the limited outdoor use pattern for
the product. The limited use pattern for RUC 161 was a mitigating factor in our decision of whether to register the
product. However, use on home lawns increases the potential for fish, invertebrate, and mammals to be exposed to the
Under Section II(C)(1) of our Procedures handbook, a major change in use pattern is defined as a change
that is likely to increase the exposure of any nontarget organism or that increases the potential for significant impact
to humans, property, or the
environment. DeltaGard meets that criteria. The procedures for reviewing applications constituting a "new active
ingredient" or a "major change in labeling" were discussed at our New York State Pesticide Product Registration
Workshop on December 12, 1995. AgrEvo was invited to attend the December 12, 1995 workshop, responded to the Department
that a representative from AgrEvo would attend, but did not attend. Our Pesticide Product Registration Section will
continue to operate under the procedures established in the "New York State Pesticide Registration Procedures" handbook
As previously noted, the cancellation of the registration in New York State for DeltaGard G Insecticide
Granules is effective 30 calendar days from the date of service of this notification.
Please be advised that AgrEvo may, in accordance with ECL§33-0713(3) and
within this 30-day period, respond by making the necessary corrections, filing a petition requesting that the matter
be referred to an advisory committee, or file objections with the Department and request a public hearing.
If no response is received within the time frame noted above, the cancellation will be final and AgrEvo
must take the necessary actions to remove the product from the channels of trade in New York State.
After the effective date of cancellation, DeltaGard G Insecticide Granules may not . be used,
distributed, sold or offered for sale in New York State. Products found to be offered for sale will be quarantined and
AgrEvo will be subject to penalties. Additionally, please provide the Department within this 30-day period a detailed
plan of action to remove the product from the channels of trade in New York State.
If you intend to reapply for registration of DeltaGard G Insecticide Granules in New York State, you must
submit a new application along with the information previously requested in our August 5, 1996 letter. The application
must meet the requirements outlined in the New York State Pesticide Product Registration Procedures handbook.
If you have any questions, please contact Maureen Serafini, Supervisor of our Pesticide Product
Registration Section, at (518) 457-7446.
