Dear Mr. Rosenblatt:

Re: Quarantine Exemption Request for Use of the following fungicides to control Australasian Soybean Rust (Phakopsora pachyrhizi) on soybean crops in New York State

    The New York State Department of Environmental Conservation, as the State lead agency for pesticide matters, hereby requests approval of the referenced application (see enclosure) under Section 18 of the Federal Insecticide, Fungicide and Rodenticide Act, as amended. The enclosed application includes the information required in 40 CFR, Part 166, Subpart B (166.20). An application has been previously submitted by the States of Minnesota and South Dakota as a group Section 18. This request contains the New York State specific information required.

    Australasian soybean rust models (Appendix C of the MN/SD request) suggest that most of the soybean acres in the United States could be compromised by soybean rust at the point that the disease becomes established in the country. In New York State, 140,000 acres of soybeans may need to be treated. Soybeans are grown in all counties of New York State, including Nassau and Suffolk counties on Long Island.

    Several products have emerged as potentially efficacious against Australasian soybean rust in international trials. Products are listed in order of greatest potential for availability and preference for use.

Active Ingredient Product Name EPA Reg. No. Company Name
Propiconazole Tilt 100-617 Syngenta Crop Protection
Propiconazole PropiMax EC 62719-346 Dow Agrosciences, LLC
Propiconazole Bumper 66222-42 Makhteshim-Agan
Tebuconazole Folicur 3125-394 Bayer Corp.
Myclobutanil Laredo EC 62719-412 Dow Agrosciences, LLC
Myclobutanil Laredo EW 62719-493 Dow Agrosciences, LLC
Propiconazole + Trifloxystrobin Stratego 264-779 Bayer Cropscience
Tetraconazole Domark 60063-RE Sipcam Agro USA
Pyraclostrobin + Boscalid Pristine 7969-199 BASF Corp.
Pyraclostrobin Headline 7969-186 BASF Corp.

    Please find a list of endangered and threatened species known to occur in New York State in Appendix C. It is expected that applications by ground equipment directly to soybean fields should not pose a problem to endangered species, especially when spray drift is kept under control. Aerial applicators will need to be familiar with those areas adjacent to sprayed fields and should check with local and Regional NYSDEC biologists for endangered species residing near the spray area. Scouting of adjacent areas near soybean fields is encouraged prior to aerial applications.

    The manufacturers of the products listed above are aware of and supportive of this request. Letters of support and use directions for soybeans have been received (Appendix F).

    Please contact Robin Hackett, of our Pesticide Product Registration Section, at (518) 402-8768 if you require further assistance on this request.
