Do inert ingredients in pesticide formulations need to be listed by name?

In pesticide formulations, inert ingredients do not need to be listed by name on the label; instead, it is sufficient to provide their composition percentage. This practice is in line with regulatory guidelines, which distinguish between active ingredients—those that control pests—and inert ingredients, which serve various functions but do not directly affect pest control effectiveness.

Inert ingredients may include solvents, emulsifiers, and other substances that aid in the formulation but do not have pesticidal properties. Since they are not the primary components that contribute to the efficacy of the pesticide, it is deemed adequate to disclose their proportions rather than requiring full disclosure of each inert ingredient. This policy streamlines the labeling process and maintains trade secret protections for manufacturers while ensuring that users have access to essential information regarding composition.

Types of information on hazardous inert ingredients may need to be shared but generally, such details are largely focused on the active ingredients and the overall safety of the product rather than a complete list of inert components.
