lambda-cyhalothrin (Karate, Force) Letter of Concern 9/93

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 

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 

Thank you for your help on this.
