Which of the following is a disadvantage of Flowable (F) when preparing a spray mix?

• A. Spray mix needs constant agitation
• B. Easy to store
• C. Non-fouling residue
• D. Compatible with all sprayers

Answer: (A)

Flowable formulations are suspensions of tiny solid pesticide particles in a liquid. Because those particles tend to settle out, keeping the spray mix uniform requires constant agitation throughout mixing, filling, and application. If agitation stops, the settled material can cause uneven dosing, reduced efficacy, and potential nozzle or screen clogging, making agitation a practical drawback of using Flowables. The other statements describe favorable traits—easy to store, minimal residue, and compatibility with sprayers—that don’t represent a disadvantage.
