Public Comment on Pyrethroid Insecticides

Below is a request by Dr. Stormy Sparks. Please take a minute to go to the EPA website to comment on this very import issue.

 

ALL pyrethroid insecticides (bifenthrin, Warrior/Karate, Mustang Max, Baythroid, Asana, Permethrin, etc.) are currently undergoing registration review at EPA.

Nine are specifically being evaluated, but serve as surrogates for all 19 active ingredients.

The preliminary evaluation shows that all pyrethroids exceed “Levels of Concern” for exposure to aquatic invertebrates. THIS IS MAJOR. If LOCs are exceeded, the exposure must be mitigated. This can be done in a variety of ways, but generally means loss of uses, reduced rates, reduced number of applications, or other use restrictions.

IF PYRETHOIDS ARE IMPORTANT IN PRODUCTION OF YOUR CROPS, YOU ARE ENCOURAGED TO SUBMIT COMMENTS TO EPA ON THIS EVALUATION.

The current deadline is January 31. An extension has been requested but has not been granted as yet. Please comment now if possible.

EPA particularly needs to know why and specifically how you use pyrethroid insecticides.

Your comments should include:

Who you are and why you are commenting (grower, consultant, etc.; acres grown and other pertinent information as to your qualifications).

Why pyrethroids are important to you (why you use them over other products; why alternatives are not adequate or preferred; etc.)

YOUR USE PATTERNS (be very specific if at all possible):

For EACH crop (and possibly season) indicate which pyrethroid(s) you use, the pest(s) targeted, the use rate, number of applications, re-treatment interval, and pre-harvest interval (particularly if a short PHI is necessary).

The general importance of pyrethroids is important (about the only broad spectrum products we have left), but the specific use information is needed to adjust the exposure estimates.
