Which option describes a disadvantage of Flowable (F) that might be relevant to performance?

• A. Safe for most surfaces
• B. Spray mix needs constant agitation
• C. Odorless
• D. Stable in heat

Answer: (B)

Flowable formulations are suspension concentrates, meaning the active solid particles are dispersed in a liquid but tend to settle out when not in motion. Because of this, keeping the spray mixture uniformly mixed requires constant agitation in the tank. If agitation isn’t maintained, solids settle, causing the concentration to drift during spraying, which leads to inconsistent coverage, under- or over-dosing in the treated area, and possible nozzle clogging. These issues directly affect performance, making constant agitation a notable disadvantage of using a Flowable formulation. The other traits listed describe favorable or neutral characteristics—being safe for most surfaces, odorless, and stable in heat—so they don’t present the same performance drawback.
