Which statement accurately contrasts agitation needs for WP and LF?

Which statement accurately contrasts agitation needs for WP and LF?

• A. WP requires good and constant agitation; LF requires moderate agitation.
• B. WP requires heating; LF requires heating.
• C. WP requires no agitation; LF requires constant agitation.
• D. WP and LF require identical agitation.

Answer: (A)

Wettable powders are finely divided solids that tend to settle out of suspension quickly in water. To keep the active ingredient evenly distributed for effective spray coverage, they require good, continuous agitation during mixing and application. In contrast, the LF liquid formulation behaves more like a true liquid and stays mixed more readily, so it generally needs only moderate agitation to stay uniform. Heating isn’t a standard requirement for either, and claiming identical agitation or no agitation for WP isn’t accurate. So the best contrast is that WP needs good, constant agitation while LF needs only moderate agitation.
