Do not have direct effect on pest, added to make the product safer (safener), more effective, or easier to use (ex: solvent or dry carrier).

• A. Active ingredients
• B. Inert ingredients
• C. Adjuvants
• D. Carriers

Answer: (B)

Non-active components in a pesticide product are inert ingredients. They do not directly affect pests but are added to make the product safer (safeners), more effective (by improving delivery, stability, or coverage), or easier to use (such as solvents or dry carriers). This description fits inert ingredients, which cover these supportive roles without being the pest-killing chemical itself. Carriers are a type of inert ingredient used to deliver the active ingredient, while active ingredients are the substances that kill or control pests. Adjuvants are additives that can improve performance but aren’t the broad category described here.
