ECA NEWS E nvironmEntal C arE a ssoCiation of i daho s pring 2012 Synthetic Pyrethroids – label changes in 2012 Changes to Label Wording – 2011-2012 EPA PR Notice 2008-1 – for “non-fogging” pyrethroid products Overview and Reasons for Label changes: In 2011 the EPA began to implement the requirement for new wording and instructions for use on all Product Labels of Synthetic Pyrethroids. These insecticides constitute a large number of the most often-used products in pest management, including such common active ingredients as permethrin, deltamethrin, bifenthrin, cypermethrin, cyfluthrin, and many others. The ruling also affects any products with multiple active ingredients where at least one of them is a synthetic pyrethroid. The timeline for compliance with this new labeling is confusing, but some product Labels began to show these changes in December 2011 and all others will be expected to comply within the first few months of 2012. It is imperative that end users of pyrethroid products carefully read the Label of the material they purchase from suppliers to be certain of the specific wording on that Label and the new restrictions that may be in place on its use. The overall intent of these changes is to minimize movement of these active ingredients into sensitive environmental areas, such as waterways or habitats of protected wildlife. Studies initiated in California, testing water in storm drains and nearby creeks, suggested that contamination with levels of pyrethroids sufficient to affect test organisms in those waters was occurring routinely. Synthetic pyrethroids, while very low in toxicity to warm blooded animals, can be very toxic to cold blooded animals (fish, frogs, reptiles) and to invertebrate animals. One aquatic invertebrate used as the test organism is Hyalella azteca , a small freshwater shrimp or amphipod. Where will the new wording be found? Much of the new wording on Pyrethroid Labels will be found in the sections on “Environmental Hazards Statements” and general “Directions for Use”, and they replace current wording with stronger wording to users of the products to avoid any application that would allow that product to move off of the intended site of use. However, there are now new limitations on the use of pyrethroid products outside of structures, and these will be extremely important to the Pest Management Professional. Environmental Hazards – intended to clarify the steps the applicator can take to avoid potential contamination. They will vary depending on the formulation – granules, liquid sprays or dust. “Directions for Use – Application Restrictions” – new wording to be added for granules, liquid, dust and ready to use formulations. In some states (CA, NY) there will be restrictions prohibiting application within 100 feet of any coastal marsh or stream that drains directly into a coastal marsh. There also may be restrictions on applications to sites that drain to habitats of protected species of animals. There may be new wording specifically restricting the intervals for a second or third application. Termite Pre-treatments are subject to label changes as well. Impact on the Pest Management Industry: • For structural general pest uses PMP’s will no longer be permitted to apply broad applications to exterior surfaces of structures, such as might be done for management of cluster flies, ladybird beetles, stink bugs, or boxelder bugs. • For turf and ornamental uses there will need to be specific attention to weather conditions, sprinkler schedules, and other factors that may encourage runoff that carries the pyrethroid material. • Attention must be given to soil conditions – frozen or saturated soils – where runoff would be likely to occur. • Extra attention must be given to applications adjacent to sidewalks or drain openings to keep all spray or granules off of these surfaces.
