What is an inert ingredient?

• A. Active ingredient
• B. Carrier or filler
• C. Surfactant
• D. Emulsifier

Answer: (B)

Inert ingredients are the parts of a pesticide product that don’t kill pests themselves. Their job is to aid delivery, handling, or stability—things like providing bulk or acting as a vehicle to carry the active ingredient. A carrier or filler fits this role because it adds volume and helps apply the product without contributing pesticidal activity. The component that actually controls pests is the active ingredient, so it isn’t inert. Surfactants or emulsifiers can also be inert in many formulations by helping the product spread or mix, but the classic example of an inert ingredient is the carrier or filler.
