Which device helps keep the spray mixture in suspension to prevent settling in the tank?

• A. Tank
• B. Nozzles
• C. Pressure Gauge
• D. Agitation

Answer: (D)

Maintaining a uniform spray mixture is essential to ensure every load applied has the same concentration. Keeping the liquid in motion through agitation prevents the solids from settling out of the suspension. When agitation is active, the mixer (often a paddle or impeller driven by the pump or an external agitator) continually circulates the contents, pulling liquid from the bottom and sending it back through the mix. This keeps active ingredients evenly distributed, reduces the risk of clogged filters or nozzles, and ensures consistent coverage across the field. The tank simply holds the liquid, the nozzles spray it, and the pressure gauge shows how forcefully it’s being pushed out. None of those by themselves keep the mixture from settling; agitation is specifically what maintains suspension and stable concentration during spraying.
