Why would you need a backpack sprayer?

Simply put, the best backpack sprayer offers the user a lot of versatility for applications that involve spraying. It can be used to disperse chemicals in on bushes or trees, in a garden, or across the lawn. A homeowner can use a backpack sprayer with detergents to clean their home exterior or other parts of their property. These sprayers can also be used to apply stains and water-sealants over wooden decks or fences.

A gardener may need to apply chemicals that will kill weeds near their vegetables. They may also need to treat a row or section of produce for bugs. In both cases, a backpack weed sprayer will save them energy and time. These dispersal devices can target individual plants or small groupings, or are capable of spraying larger swaths of vegetation.

Container gardens are popular choices, especially in more urban settings. Small containers that contain individual plants or larger ground containers that contain a variety of species can be sprayed using the same device. The plants can be covered quickly and without the chemicals spilling or spraying outside of the containers. A hanging garden is easier to maintain as the wand on a backpack sprayer provides an extended reach.

For those of us who constantly battle weeds in our yard, this type of sprayer allows us to cover our property quickly with a pinpoint application. This is also the case for driveways and sidewalks. The versatility of these sprayers makes treating bushes, shrubs, and trees easier. The extended reach provided by the wand can spray in locations that would require step-ladders otherwise.

Larger properties or community gardens can be sprayed more quickly. Individuals who operate a property maintenance service will find a backpack sprayer saves both money and time on the job site.

Features to consider

Battery powered backpack sprayers vs manual power

Traditionally, even the best backpack sprayers have been manual units. A handle is used to pump up the pressure in the backpack. One hand is used for pumping while the other hand is used to activate the wand and to direct the spray. A manual sprayer can tire an operator’s arm out, so a good feature to look for will be a sprayer that can be used either left or right-handed.

Due to their simple design, a manually powered sprayer weighs less than a motorized backpack will. The manual applicator does not rely on an electrical motor, making these units less expensive. The sprayer is ready to go at any time and will require less maintenance.

A battery powered backpack allows the user to spray without having to wear their arms out. An electric motor builds the pressure required for operation. Remember to keep in mind that a battery powered applicator will cost more, weigh more, and will require more upkeep.

Pressure (PSI)

The pump on a backpack sprayer builds-up pressure in the container, that is measured in Pounds per Square Inch (PSI). A backpack applicator is able to create pressures ranging from 15 to 95-psi (some commercial units can go even higher). Manually powered backpacks tend to spray around 60-psi or more. This is a feature that favors battery powered units for those who will require higher pressures.

The generated pressure provides the consistency of the spray as well as the distance that the spray reaches. Motorized sprayers are capable of reaching two or three times farther than a manually powered unit will. With some products, the pressure will decrease slowly as the reservoir is emptied. This will shorten the distance the sprayer is able to reach as the session progresses.

A decrease in the pressure can also affect the consistency of the spray as well. This can be important for chemical application and crucial for detergent, sealant, and stain coverage. A great feature to look for on backpack sprayers would be a valve that regulates pressure. Another item that can prove beneficial is a pressure gauge.

Main components of a backpack sprayer

Tank and capacity

One of the features that make a backpack sprayer stand out is the tank’s capacity. Most residential sprayers have a tank capable of holding anywhere from two gallons to four gallons of liquid. This size range should be fine for most residential properties. Larger properties may require tank sizes that are found on larger commercial backpack sprayers.

Sprayer wand

Another consideration is the wand attached to the backpack. The main advantage of a good wand is the reach that it provides. A wand allows the user to reach above their head to spray or to apply the liquids near the ground without having to bend over. They also allow a homeowner to reach into bushes or plants that contain branches or thorns that may be painful to touch. The wand and trigger should be comfortable to use over an extended period of time.

Garden sprayer nozzles

Nozzles provide the pattern and spray flow for the unit. The best backpack sprayer will have multiple nozzles for various patterns or an adjustable nozzle that eliminates the need for more than one nozzle.

The amount of liquid a nozzle can spray at one time is also an important consideration. Nozzles that can deliver up to a half-gallon of liquid per minute from the backpack fogger are satisfactory.

Backpack sprayer harness

Another design feature to look at is the harness of the backpack fogger. It should be comfortable to wear for extended periods. Waist straps can add additional support and provide increased stability while the backpack pump sprayer is being used.

Fertilizer, pesticide and herbicide sprayer features

Most garden sprayers will be required to be compatible with general liquid fertilizers, pesticides and herbicides. Due to the rigid materials used in modern weed sprayers, this should not be an issue. But as best practice, always rinse the backpack sprayer tank and wand before storage with fresh water to get rid of remains of chemicals.

Backpack sprayers are particularly useful when covering larger areas infested with crabgrass (see crabgrass killers here) or dallisgrass.

Best protection is always prevention, so looking after the lawn properly and using quality seeds is very important.

Conclusion – The Best Garden Sprayer for 2018

As we can see from the reviews above, there are many features that can make up the best backpack sprayer. One of the most important design features a user must consider is battery power or manual pumping. For smaller gardens or yards a handle pump backpack sprayer will work just fine. Larger properties or intensive workloads may require a homeowner to favor the less labor-intensive electric motor power for the backpack fogger.

The best garden sprayer will be capable of holding enough liquids to cover the project. It will also provide the reach needed to save time. Again, smaller gardens and projects can be covered by a hand-pump unit while a large yard will benefit from the extra spray length offered by a battery-powered applicator. A larger selection of nozzles will provide a greater variety of applications.

Finally, don’t forget that small hand-held tanks are available for those smaller jobs.
