Which statement about granules is true?

They dissolve instantly in water. They are highly volatile. They require heat to activate. They have low drift potential.

Correct Answer:

They have low drift potential.

Explanation:

Granular formulations are designed to stay where they are spread, which minimizes drift. Their solid, heavier particles settle quickly and are not easily carried by wind, so they remain near the application site and deliver the active ingredient where it’s intended. This is what gives granules their low drift potential. Granules don’t dissolve instantly in water; they’re made to release the active ingredient gradually as moisture interacts with the material. They are not highly volatile, since volatility involves turning into a vapor, and granules remain as solids rather than evaporating. They also don’t require heat to activate; many are moisture-activated or rely on soil moisture to release the active ingredient, rather than heat.
