True or False: All the ingredients active and inert in a formulation must be named on the label.

The statement is false because while active ingredients must be listed on the label of a pesticide formulation, inert ingredients do not have to be named specifically. The Environmental Protection Agency (EPA) requires that active ingredients, which are responsible for the pesticide's effectiveness against pests, be clearly identified by name and percentage on the label. However, inert ingredients—those that do not have a pesticidal effect—can be listed collectively under the term "inert ingredients," without needing to specify each individual component.

This distinction is important because it allows manufacturers some flexibility in protecting proprietary formulations while still providing regulators and users with crucial information about the efficacy and safety of the product. Consequently, while all active ingredients must be disclosed, only a general category for inert ingredients is mandated, leading to the conclusion that the correct answer is false.
