|New FMC videos explain pyrethroid label changes.|
I shared EPA's May 1 label interpretation with Dr. Jim Fredricks at the National Pest Management Association. He and his legislative colleague, Bob Rosenberg, followed up with EPA on this information. In an email dated 19 June 2012, Rosenberg received a response from EPA stating that their original "response (the one I received) was not correct... the 10 mph wind restriction applies only to products labeled for preconstruction termiticide applications." [my emphasis]
To those of you who read my comment, I apologize for passing on the wrong information. Thanks to NPMA for following up and ensuring that all of us get the correct information about pyrethroid label changes and what they mean. BTW, this is a great example of the kind of service tha the NPMA provides its membership as it looks out for the interest of the industry.
I have since removed the incorrect information from the April post's comments; however pyrethroid labels may include advisory language recommending application should be made during "calm weather when rain is not predicted for 24 hours". This may be more difficult to gauge and document than the 10 mph requirement.
As usual, if in doubt, read the label. If it's a pyrethroid label, be extra careful over the next few months to check every pesticide container. During this transition period some containers will have labels that have the new language, and others will not. While technicians are OK if they use a product with the old language, it would be a good idea to train and require all your employees to start following the tighter restrictions now.
FMC Professional Products has produced some nice new videos explaining the new pyrethroid labels. Check them out at the FMC YouTube Channel.
