Let’s assume now that you have a boom sprayer. ![]() Therefore, make sure you use the proper units and/or conversions in your tank mix calculations. For boom sprayers, the application rate is usually given in gallons per acre (GPA). For small sprayers, the rate may be expressed in ounces, quarts, or gallons per 1,000 feet. Calculations and concepts are the same whether you are using a manual backpack sprayer with a 5-gallon tank, a lawn mower/ATV sprayer with a 15-gallon tank, a pull-type sprayer with a 500-gallon tank, or a 1,500-gallon self-propelled sprayer. The amount of chemical needed per tankful depends on the recommended rate and the size of area you intend to treat per tank of spray. The second label recommendation not only requires proper calibration and operation of the sprayer, but it also requires that the spray mixture contains the right concentration of the actual product applied. The first requirement can be attained by proper calibration and operation of the sprayer. ![]() Labels give two types of application rates: volume of spray mixture (pesticide and water) applied per unit area (gallons per acre, ounces per 1,000 square feet, etc.), and the amount of actual chemical applied per unit area (ounces, pints, or quarts per acre or 1,000 square feet).

For information on calibrating a sprayer, see FABE-520 and FABE-529 which describe two different calibration procedures. One way to achieve this is to make sure the sprayer is in good condition, set up properly, works well and is calibrated correctly. The applicator’s job is to apply the amount recommended on the label. The directions on the container label tell which application rates give the best results. We cover every major style used by non-professional gardeners-from small handheld options ideal for potted plants to large-capacity sprayers for large yards-and offer products to consider across price points, from value-packed to premium picks.Applying herbicides at the proper rate is essential to achieving satisfactory pest control. All of the garden pump sprayers we feature are from top brands, with average customer ratings of at least 4 stars.

Also, note that some garden sprayers aren’t made for acid-based solutions or other corrosive chemicals. ![]() Generally speaking, things like adjustable or extra nozzles, locking triggers, telescopic wands, and ergonomic handles will make operation easier and more convenient, especially if you're maintaining a large property. ![]() There are several other features to consider, depending on the style of sprayer you choose. The most basic sprayers are manual pumps, but there are also higher-end battery-powered options. Non-professional garden sprayers are typically made of polyethylene plastic and/or stainless steel, and can hold anywhere from a few ounces to several gallons stored in tank that you wear on your back. You’ll want a sprayer large enough that it won’t need to be refilled every 20 minutes, but not something that’ll needlessly weigh you down. When shopping for a garden pump sprayer, first think about the amount of ground you have to cover.
