A power sprayer, also known as a pressure sprayer or sprayer pump, is a versatile agricultural tool used for the application of liquids, such as pesticides, herbicides, fertilizers, and disinfectants. It utilizes pressure to atomize and distribute the liquid in a controlled manner.

The key feature of a power sprayer is its ability to generate and maintain high pressure, which allows for efficient and precise spraying. It typically consists of a tank to hold the liquid, a pump to generate pressure, and a spray nozzle or boom to disperse the liquid over the target area.

Power sprayers are available in various sizes and configurations, ranging from handheld models to larger tow-behind or mounted units. They can be powered by gasoline engines, electric motors, or connected to the power take-off (PTO) of tractors.

Power sprayers are widely used in agriculture for crop protection, weed control, and fertilization. They provide uniform coverage and effective distribution of the liquid, reducing the risk of uneven application or wastage. They are also used for pest and disease control in orchards, vineyards, and greenhouse operations.

In addition to agricultural applications, power sprayers are utilized in landscaping, horticulture, forestry, and public health sectors for various spraying needs.

Safety precautions should be followed when operating power sprayers, including wearing protective clothing, proper handling of chemicals, and adherence to recommended application rates and guidelines.
