Protocol Streamlines Development of Storage Stability and Corrosion Characteristics Studies for Some Pesticides

The new test protocol that will, for some pesticide products, reduce the time and costs involved in conducting a one-year study required to fulfill the agency’s data requirements for pesticide registration and re-evaluation. Pesticide registrants are encouraged to consider this protocol as an alternative to the  Shelf life/Storage Stability 

The new accelerated study, which takes only 14 days to conduct, provides adequate data in some circumstances to allow the EPA to make a regulatory finding regarding the stability of a pesticide product and the effect of the formulation on the product packaging.  It has been observe that there were no significant differences between the test results from the new accelerated test protocol and the existing test protocols which take one year to complete.  The Office of Pesticide Programs’ Science Policy Council reviewed the new protocol and determined that it provides high-quality data.

Not all products and materials, however, are suitable for the new accelerated study protocol because it tests pesticides at an elevated temperature of 54 degrees C.  Registrants must consider the physical and chemical properties of their pesticide products and determine whether the new accelerated protocol or the one-year study is appropriate.
