Developing an inert petition strategy: five key considerations

Inert ingredients are just as important in product formulations as their active counterparts. However, they are not always given the focus they deserve. As the US Environmental Protection Agency (EPA) must approve the inert ingredient first, the petition can become a limiting factor in the pesticide registration process. Therefore, it is important for registrants to identify inert ingredients early, understand their approval status, and consider the impacts of an inert petition on any anticipated regulatory timeline. In this paper, Abigail Wacek outlines the five key elements companies need to consider when developing an inert petition strategy.
