Which of the following is a disadvantage of Dry Flowable/Water Dispersible Granule formulations?

• A. They are easy to mix with water.
• B. They do not require constant agitation.
• C. They are non-abrasive to equipment.
• D. They can be abrasive.

Answer: (D)

Dry Flowable/Water Dispersible Granule formulations are dry particles designed to disperse in water for application, but their solid particles can act like tiny abrasives. As the mixture is pumped and circulated, these hard granules can wear down equipment components such as pump seals, gaskets, impellers, and nozzle internals. That wear leads to more maintenance, potential leaks or spray inconsistencies, and shorter equipment life, which is why abrasion is a documented disadvantage of this formulation type. Some statements describe practical positives—easy to measure and mix, good shelf stability, and predictable dispersion—while others imply that constant agitation isn’t needed. In reality, agitation is often important to keep the suspension uniform and prevent settling, so claiming no need for agitation isn’t accurate. Saying they are non-abrasive to equipment would also be incorrect.
