How Do I Choose the Best Backpack Sprayer?

A backpack sprayer can help keep your garden and lawn looking like spring all year round. From flower beds to farm fields, chemical applicators can keep animals and pests away. They usually have a tank, a hose, and a wand with separate spray nozzles, and inside the tank there will be one of three types of pumps.
  • Piston pumps are the simplest, and produce a high PSI for thicker chemicals.
  • Diaphragm pumps have closed-off cylinders that are more resistant to corrosive chemicals over years.
  • Motorized pumps are the easiest to use, but the hardest to clean and replace internally.
So lace up your work boots, grab your gloves, and put on your best face shield while we take you through the different types of backpack sprayers!
Price
A variety of factors affect the price of a backpack sprayer, including features, design, materials, size, and manufacturing quality. Tanks can range from small ½-gallon models to large, 5-gallon tanks. Although it may be tempting to buy a cheap backpack sprayer, any container of hazardous chemicals needs to be dependably reinforced.
Features
As any gardener and landscaper will know, it’s important to have different nozzles depending on the task. A single stream can be perfect for large ranges and huge fields, but a gentle mist or spray may be more appropriate for your flowerbeds and leaves. Hose and wand length can help for hard-to-reach hanging plants, and special features such as a locking valve for easy shut-off can prevent leaks during storage. Look for extra features such as padded straps, additional belt straps, a handle for carrying, and name-brand seals for longevity.
Construction and Design
As with most tools, the beauty is in the details. High-density polyethylene tanks are naturally resistant to corrosion and chemical destruction, and are standard for most backpack sprayers. Tanks are usually designed to fit comfortably and distribute weight evenly over long periods of time, and the cleverest designs have wide or funneled mouth openings for spill-free filling. Hose construction is usually clear polyethylene as well, and wands are normally created with stainless steel, brass, or more polyethylene.
Performance and Ease of Use
When choosing a backpack sprayer, most will require some quick and easy assembly. Double check to make sure you have any necessary tools before arrival. After that, the most important choice is going to be a manual vs. automatic sprayer. Both are convenient and easy to use, although automatic sprayers can help if you have multiple acres of fields to cover without aerial support.

Automatic backpack sprayers operate differently from manual pumps, and have their pros and cons. Larger fields may be easier to spray continuously, but parts, repair, and overall cost may be more expensive. Range is normally predetermined and unalterable, but you simply won’t find a more convenient way to apply pesticides, protective chemicals, and pest repellants over a large surface area.

Manual applicators come in two varieties: diaphragm pumps and piston pumps. In manual sprayers, a separate chamber inside the tank collects liquid and pressurizes it. Manual backpack sprayers usually operate between 25 and 90 PSI — enough for a 35 to 50-foot range. The less complicated design makes repair and replacement of parts easier and less expensive, although it will take more effort to spray larger crops.
