Dear Mr. McMaster:


The New York State Department of Environmental Conservation has reviewed your letter 
of January 31, 1995 regarding the registration of your pesticide products Broadstrike + 
Dual and Broadstrike + Treflan.


The Department will allow the use of these products in the 1995 growing season in 
New York State providing DowElanco continues to contribute to the collective registrant 
effort in the development of the generic Corn Herbicide Management Plan as stated in our 
registration letter of December 14, 1994 (copy enclosed).


Groundwater monitoring samples as described in our December 14, 1994 letter, must be 
collected by the fall of 1996 by either the State developed monitoring program, or in 
the absence of a State program, it will be the responsibility of DowElanco to collect 
these samples and provide the analytical results to the Department for review.


A mesocosm study will not be required at this time. However, if adverse impacts are 
noted to non-target aquatic vegetation resulting from the normal use pattern of the 
Broadstrike products, the Department will require a runoff study or additional limiting 
label language for use in this State.


The Broadstrike + Dual product will retain the classification of "restricted use" 
due to the potential of the formulated products to impact the groundwater resources 
of New York State.


The restricted use classification has been a consistent approach used in all 
registration decisions where groundwater impacts are a concern.


Enclosed is an updated Certificate of Pesticide Registration reflecting the status 
of Broadstrike + Treflan.


Your New York State Pesticide Product Registration expires December 31, 1995. 
A continuance of this registration will be dependent upon any observed adverse 
effects to non-target and aquatic vegetation resulting from the normal use pattern 
of the Broadstrike products and DowElanco's contribution to the continued efforts of 
the development of the generic Corn Herbicide Management Plan which includes the 
monitoring component.


The results, interim or final, of the prospective groundwater studies conducted by Ciba 
Plant Protection for the presence of metolachlor and selective degradates must be
delivered to this Department, when available.


Additionally, Jim Colquhoun (Phone 518/457-6178), Chief of the Division of Fish 
and Wildlife's Bureau of Environmental Protection, would like to speak to you about 
DowElanco doing a runoff study. Please call him to discuss.


Please contact Ms. Maureen Serafini, Supervisor.of our Pesticide Product Registration 
Section, at (518) 457-7446, if you have any additional questions on this registration.


Sincerely,
Norman H. Nosenchuck, P.E.
