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.

This is thanks to an 8-amp hour, lead-acid battery that produces power for much longer durations than smaller lithium options.

Overall, this sprayer is easy to assemble, simple to use, very sturdy, and extremely maneuverable. It’s ideal for those needing a do-all backpack sprayer that offers top-shelf battery life.

Key Features

Power Source: Manual
Material: Brass
Tank Capacity: 4 gallons
Maximum Pressure: 150 psi
Weight: 12.8 pounds
Warranty: 1 year
Price: $84.97

Pros

Good max psi
Easy to maintain
Durable 21-inch poly wand

Cons

Manual power source
Heavier than competing products with plastic components

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.

The Tomahawk 5-Gallon Backpack Sprayer is a powerful and versatile option for spraying everything from mosquito insecticide to liquid fertilizer. The versatility comes from its easy throttle control, 50 to 450 psi, and the Tomahawk’s wide range of attachments.

The most versatile attachment is the twin-tip nozzle, which produces small droplets in a wide spray pattern. If you need to spray tall trees or buildings, you can swap to the foundation gun, which can spray up to 30 feet. Or if you need a nice even spray of medium droplets, the fan tip nozzle is a great choice. One thing to note is that the sprayer comes with one nozzle, and extras are sold separately.

The 50 to 450 psi range and 25-foot hose length makes it possible to cover up to 1 acre in just 15 minutes. This model also boasts lower vibration levels, which is suitable for those who will be in the field for longer periods. It’s compatible with herbicides, pesticides, and insecticides.

This is a viable selection for most needing a fuel-powered backpack sprayer, but especially those wanting some of the unique features this one offers, such as the versatile nozzles and powerful 450 psi.

Key Features

Power Source: Manual

Warranty: 5 years
Price: $149.99

Pros

Great self-cleaning technology
Incredible warranty
Impressive price point

The Chapin 63900 requires less cleaning maintenance due to the patented JetClean pump technology. It uses a powerful burst of liquid through the tank filter with each downward pump stroke, effectively keeping the filter free of debris and clogging. It’s compatible with herbicides, pesticides, and most fertilizers.

The Chapin breaks the mold with its external pump, in a market where most sprayers have internal pump systems. It also includes a large opening with a filtration system to pour liquids effectively and safely into the tank. It even sports a durable wand handle with an ergonomic grip that feels more comfortable than most. This model has a 48-inch hose, stainless steel wand, and three nozzle types (fan, cone, and adjustable brass). The swing-away pump handle can be set up for right- or left-handed use.

While this sprayer does require cleaning, it is perfect for those who tend to fall short with this chore, as it can withstand less-effective cleaning maintenance than other options on the market.

Another area this sprayer really shines is the back support and padding. It offers more comfort than most other options on the market. The padding is in the right spot and provides good support in key areas.

Things to Consider Before Buying One of the Best Backpack Sprayers

Using backpack sprayers to spray water during a controlled burn. Realtree

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.

FAQs

Q: What is the best backpack sprayer to buy?

This varies depending on specific needs. Affordability, capacity, design, component materials, power source, pump type, pump location, weight, and more, all impact what sprayer will be best for an individual.

Q: What coverage area is a backpack sprayer best suited for?

Generally, backpack sprayers are limited to those spraying less than one acre.

Backpack sprayers are quite easy to maintain, but this varies depending on pump type, pump location, power source, and component materials.

Backpack sprayers can be purchased at farm, home, hunting, and garden stores, either in-store or online. Common retailers include Amazon, Farm and Fleet, Home Depot, Lowe’s, Sportsman’s Guide, Tractor Supply Company (TSC), and independent (local) retailers.

Q: How much should I spend on a backpack sprayer?

Oftentimes, backpack sprayers range from $25-700. Cheaper ones offer fewer features, and in some cases, less quality. More expensive options tend to offer more features and better durability.
