Which sprayer type commonly includes mechanical agitators to keep the pesticide mixture from settling or separating?

• A. Hydraulic Sprayer
• B. Knapsack Sprayer
• C. Labeling
• D. Micron

Answer: (A)

Keeping pesticide mixtures uniform is essential because many formulations tend to settle or separate over time. An agitator stirs the liquid so solids stay in suspension and the liquid remains consistent as you spray. In hydraulic sprayers, the pump pressurizes the tank mix and pushes it through the nozzle, which can cause components to separate if there’s no constant movement. A mechanical agitator—like an impeller or paddle inside the tank—keeps everything in suspension, helping maintain even concentration, reducing nozzle clogging, and producing a uniform spray. Knapsack sprayers are portable and may rely more on manual shaking or intermittent agitation rather than a built-in mechanical agitator. That’s why agitation is not as universally built into them, even though some models might have one. The other choices aren’t sprayer types at all—one refers to labeling, and the other to a measurement related to spray quality—so they don’t describe devices that would include an agitator. So, the hydraulic sprayer is the type most commonly designed to include a mechanical agitator to keep the mixture uniform during application.
