Pesticide formulations are typically a mixture of active ingredients and what other components?

• A. Active and inert ingredients
• B. Active and insoluble ingredients
• C. Active and organic solvents
• D. Active and volatile solvents

Answer: (A)

Pesticide formulations combine the active ingredient with inert ingredients. The inert components act as carriers and additives that help with handling, mixing, stability, and delivery—things like solvents, surfactants, spreaders, stickers, and other carriers. They’re not designed to attack the pest themselves, but they’re essential for getting the active ingredient to work effectively and safely.

The other options don’t fit as well because “insoluble ingredients” isn’t a standard category used to describe formulations, and “organic solvents” or “volatile solvents” are specific types of inert components rather than the general concept. In practice, a formulation is built from the active ingredient plus a mix of inert ingredients to optimize application and performance.
