A solvent or dry carrier in a pesticide formulation is an example of which ingredient type?

• A. Active ingredient
• B. Inert ingredient
• C. Safener
• D. Carrier

Answer: (B)

In pesticide formulations, the ingredients are split into the active ingredient (the chemical that controls pests) and inert ingredients, which are all the non-active parts. A solvent or a dry carrier is used to dissolve, suspend, or carry the active ingredient so it can be applied effectively. They don’t have pesticidal action themselves, so they’re classified as inert ingredients. A safener is a different type of additive that helps protect crops from injury, and a carrier is a specific kind of inert ingredient used to give the product its physical form (like a dust or granule), but the general category for these non-active components is inert ingredients.
