The correct answer is the term for hand-held devices designed to regulate the application of liquid from a tank while being connected to a hose, which is referred to as a spray gun. These devices typically allow users to control the flow and direction of the sprayed liquid, making them particularly useful in turf and ornamentals applications for achieving precision in the treatment of plants and lawns.

Spray guns are essential tools for applying pesticides, herbicides, and fertilizers effectively, as they provide the user with the flexibility to adjust the spray pattern and pressure according to the specific requirements of the application. By employing a spray gun, practitioners can ensure even coverage while minimizing the risk of overspray or environmental contamination.

In contrast, pressure sprayers are generally larger devices that may not always be hand-held and often involve more complex operating mechanisms. Liquid applicators can encompass a broader range of devices, including those that are not exclusively hand-held. Hand pumps refer to devices that operate through manual pumping action, but they may not always provide the regulation and precision that a spray gun offers.
