Backpack sprayers are a common tool in the land manager’s arsenal, and these handy tools are ideal for small-scale spraying. A lot goes into deciding if you need one, and if you do, how to make the right selection.
I’ve spent hours planting and maintaining food plots, and that’s taught me that the right sprayer can make all the difference. South Carolina Wildlife Partnership State Director and Mossy Oak Gamekeepers Pro Staffer, Travis Sumner, manages about 2,000 acres, and he agrees. Most of the time, he’s using larger implements, such as a three-point hitch boom sprayer. However, in some instances, a backpack sprayer is just the right tool. So, who is the backpack sprayer for?
“Look at the amount of work to do on the property,” Sumner said. “What type or size of sprayer do you need to have to get the job done?” If your needs top out at 4 to 5 gallons of water, foliar fertilizer, or herbicide, then a backpack sprayer is a great choice. Then you just need to whittle down the sea of options to the right one for you.
That’s where this review comes in. I’ve done the leg work for you by using my years of land management experience to pick the best backpack sprayers for a wide range of use cases.

The Field King 4-Gallon Sprayer offers an internal, no-leak pump design. This makes it safer to use with harmful chemicals. It also has an internal piston pump that delivers up to 150 psi, which is incredible, especially at a budget price point. That said, it can maintain a continuous 25 psi. In the pressure department, it outperforms other options much more expensive than it.
It also has a premium, lockable shut-off valve with brass components, in-line filter to reduce clogging, easy-access pump, and no-tools-needed seal changes. It comes with four nozzles, including an adjustable brass nozzle, two flat fans, and a foaming nozzle. So the Field King can do the work of both piston and diaphragm sprayers.
The 190328 model is a great selection for those wanting a budget-level backpack sprayer. However, the 190348 model is virtually the same, except it offers better back support with a full back pad. It costs about $20 more, but for some, it’s worth the extra money.

Things to Consider Before Buying One of the Best Backpack Sprayers
There are many different things to consider when choosing a sprayer. While other factors exist, affordability, capacity, design, component materials, power source, pump type, pump location, and weight are the most important ones.
Affordability
In an age of heavy inflation, price matters more than ever before. Generally, backpack sprayers range from $25 to 500, but most options at the top end of that range aren’t quite worth the price tag (in my opinion).
Capacity
Each backpack sprayer offers a different capacity. Those with greater capacities hold more liquid, translating to larger coverage areas and longer durations between refills. But the more liquid you add the heavier your backpack sprayer becomes.
Design
Different sprayers come with different designs. This is especially true for the tank. Various designs impact comfort, though. Design elements also impact the backpack straps, hose, wand, and nozzle.
Build Material
Sprayers are crafted from metal or plastic. Generally, metal ones are more durable, but are heavier to carry and cost more. Plastic options are less durable, but are lighter and cost less.
Power Source
Backpack sprayers are available in three power sources: battery, gas, or hand pump. Obviously, these things impact psi. Battery packs are the most common power source. It better controls psi and is generally more reliable in controlling output. Hand-pump sprayers require more physical labor to power the unit but are usually lighter to carry. Gas-powered pumps are more powerful, and spray farther, but are heavier and ultimately cost more.
Power Duration
How long a sprayer can last between refills or charging is an important thing to consider if you’re working on a big project.
Pump Type
There are two types of pumps. It’s important to select between piston pumps and diaphragm pumps based on specific needs. Piston pumps are more popular but aren’t ideal for abrasive sprays, which can cause leaks and other malfunctions. A diaphragm pump is better for sprays that aren’t compatible with a piston pump. Also, there are psi differences between the two. Diaphragm pumps produce a lower pressure.
Pump Location
Some pumps are located on the outside of the sprayer, which is easier to maintain and repair. However, they can lead to leaks, which can even get on the person. Others have pumps on the interior. This makes for more time-consuming repairs but is not as messy with leaks.
