High-volume liquid application pumps have which characteristic?

• A. They use only dry formulations
• B. They mix pesticide in advance and store on-site
• C. They pump directly from the pond water with no mixing
• D. They take water from the application target and add pesticide to it

Answer: (D)

High-volume liquid application pumps work by injecting the pesticide into the water that is being pumped for application, using that water as the carrier. This means the mix is created on the fly as the water flows through the system, resulting in the correct dilution and even coverage over a large area. It also avoids storing pre-mixed solutions and aligns with typical label directions that require the pesticide to be added to the water at the point of use, not pre-mixed in advance. In short, the water from the application target becomes the diluent, and the pesticide is metered into it as it’s pumped.
