Dear Dr. Rutz:
The Department registered Force 1.5G Insecticide on September 20, 1993 as a
granular soil-applied product for control of insects on field corn, popcorn,
and seedcorn. This product contains the active ingredient tefluthrin and is a
federally restricted use pesticide due to its toxicity to fish and aquatic
organisms.
One of the issues of concern raised during the registration review process was
aquatic toxicity. The registrant provided the Department with additional
information relating to product reformulation and label amendments, which we
have determined will diminish the probability of fish kills, if used according
to the approved label.
The critical factor in avoiding aquatic toxicity is the incorporation of the
product into the soil at the time of planting. The current approved labeling
is very specific as to the method of application and the need to incorporate
the product into soil.
We would appreciate the assistance of Cornell University through the
Cooperative Extension Network (CENET) or other available educational media in
educating the agricultural community in the proper use of Force 1.5G
Insecticide.
Thank you for your help on this.
Sincerely,
Norman H. Nosenchuck, P.E.
