The backpack sprayer is quickly becoming a favorite among landscapers, gardeners, and pest control experts, as well as renters and homeowners who just wish to have a weed- and insect-free outdoor environment.

The ergonomic design of a backpack sprayer allows you to carry fertilizer, herbicide, insecticide, or any other liquid on your back instead of lugging about a hefty metal cart or a portable sprayer. The tool also enables you to spray a consistent stream from a range of nozzles to cover not just the regions directly underneath your feet but also places that are difficult to reach, such as under the deck.

Reasons to buy a backpack sprayer: 

  • Good for spraying anything liquid – from herbicides to water;
  • Good for the spot weed control;
  • Affordable;
  • Easy to clean and fill in;

The Field King Professional Backpack Sprayer by D.B. Smith can let you take control of your gardening duties in a flash, whether you need to fertilize a garden or lawn or control pests on fruit trees in the orchard.

The Buyer’s Guide

Types

1) Piston backpack sprayers

The up-and-down action of piston pumps distinguishes them, and they are housed in a chamber inside the tank. These sprayers usually allow for a reasonable amount of pressure, approximately 90 psi. When you “pump” the lever, it produces pressure that drives the liquid down into the wand, allowing you to spray precisely the quantity of liquid you want.

Piston sprayers are a less expensive choice. You can’t use them with very abrasive chemicals, however, since the chemicals would ruin the piston.

2) Diaphragm backpack sprayers

Diaphragm sprayers are more costly than piston sprayers and function in a similar way to piston pumps but without the internal cylinder. The diaphragm is moved by pumping the handle, which results in pressure. Chemical resistance is significantly better with diaphragm sprayers, and you may use powders as well as liquids. Diaphragm pumps provide faster pressure when you require it, but they may be more difficult to maintain.

3) Manual backpack sprayers

The most frequent form of sprayer is the manual backpack sprayer, which requires you to run the hand pump. The pressurized liquid is driven up into the wand and ready to spray once you pump the handle.

Manual sprayers are inexpensive, but if you use them for an extended amount of time, they might cause hand fatigue. However, most manufacturers now include high-powered pumps in their sprayers, making them quite simple to use.

A good-quality manual sprayer can do the job successfully if you are treating lesser infestations or have a smaller property. Some sprayers include an adjustable handle that allows you to switch between left and right-handed operation, making it even simpler to use.

4) Motorized backpack sprayers

If you’re going to treat a bigger area, a motorized model with a strong battery will get the job done fast and reduce the pressure on your hands from having to keep pressure on the handle all the while. While motorized sprayers make the work simpler and faster, they are also more expensive, heavier, and need more maintenance.

Basic components: 

  • Tank. Nowadays, most backpack sprayers are relatively lightweight, thanks to small tanks made of polyethylene plastic, which is both robust and chemically resistant, as well as UV protected. A spray tank may hold anywhere from 2 to 4 gallons of liquid, making it excellent for home use. Tanks may be heavier if they hold a bigger capacity, even if they are designed to be as light as feasible. A 4-gallon tank can handle normal activities like feeding a lawn or treating an insect infestation in a yard ranging from 5,000 to 10,000 square feet;
  • Straps/harness. Because backpack sprayers are meant to be mobile, they will include straps or a harness that slips over your shoulders and over your chest to disperse the weight, allowing you to operate the wand and complete other chores with your free hands. Shoulder straps and a high-quality harness may make gardening and other home maintenance tasks much simpler. Even while most backpack sprayers are small, when they are full of liquid, they may be rather heavy. So search for a sprayer with cushioned chest, shoulder, and waist straps that can be adjusted. If you’re dealing with a larger and heavier backpack sprayer, a harness is also a smart idea;
  • Pump. The pump draws liquid from the tank and transfers it to the pressurizing chamber, where seals and valves hold it under pressure until you pull the pumping lever/valve on the unit’s wand, which then shoots the liquid out through the nozzle in a powerful spray;
  • Wand. The wand is the extended shaft that lets you direct the liquid and sprinkle it onto the target of your choice. It also makes it easier to administer the liquid in difficult-to-reach spots, enabling you to spray far over your head or securely apply the liquid to plants with thorns or spiky leaves;
  • Nozzle. Because it regulates the spray flow and pattern, the nozzle is the most critical portion of the sprayer. The nozzles on most backpack sprayers may be changed from a continuous jet stream to a fan spray. Alternatively, they may provide you with different spray pattern alternatives, such as a high foaming nozzle. Some nozzles have a flow rate of 0.3 to 0.5 gallons per minute. Plastic nozzles may save money on the sprayer, but they will break down over time. Nozzles made of bronze or brass are more costly. These nozzles, on the other hand, may serve longer and save money in the long run;

Safety

Backpack sprayers come with a variety of features that might assist decrease operator fatigue when spraying. Some include cushioned, adjustable straps and contoured tanks that give a better fit for a wearer. They may be equipped with a cushioned harness or chemical-resistant rubber seals and gaskets to prevent leakage.

Durability

The tanks on most high-quality sprayers are composed of high-density polyethylene with UV protection. You’ll need a sprayer that doesn’t spill all over you if you’re going to be fertilizing or performing a lot of pest control. So search for chemical, leak-resistant, industrial-strength hoses and seals.

Shut-off mechanism

A lockable shut-off device may generally be installed on the handle. You may use this function to control the discharge of any liquids or chemicals and prevent them from leaking when you don’t want them to.

PSI

The level of pressure a backpack sprayer can deliver via its nozzle is measured in pounds per square inch (PSI). A backpack sprayer’s typical PSI is roughly 70 PSI, while smaller versions may use as low as 40 PSI and bigger units up to 150 PSI. Knowing PSI is critical for your backpack sprayer to function properly.

In a smaller yard, too little pressure will result in an uneven spray, reducing the efficiency of the contents, while too much would be excessive. A sprayer with a PSI 70 or above can be your best choice if you have a big yard with numerous hard-to-reach locations or if you’re a professional who works in a variety of different-sized places. A modest PSI rating of 40 to 70 is more than adequate to spray your area for individuals with average/small yards.

Weight

When going out to mow the lawn, you must have a backpack sprayer with you. As a result, it is suggested that you use a compact backpack sprayer. Typically, sprayers in these categories weigh between 7 and 15 pounds.

How to Use a Backpack Sprayer:

Gently stir the prepared chemical into the tank after mixing/diluting it. When pouring, be careful not to get any chemicals on your skin or the ground.

Screw the tank lid on firmly, strap the sprayer to your back, and adjust all straps until they are sturdy and snug.

From 10 to 15 times, pump the handle Maintain steady pressure within the backpack tank by pumping every 5 secs or so. You’ll have to thoroughly prime your sprayer each time the pressure goes off if you skip this step. Or make sure the battery is fully charged if you use a motorized model.

Simply position your wand in the direction you want to spray and pull the trigger. There are a lot more processes to spraying, but I’m not going to go through them in this post.

When you’re through spraying, be sure to clean both the interior and exterior completely, disassembling and cleaning each item.

Finally, put the backpack sprayer back together and store it or charge the battery. Plastic sprayers should never be left outdoors in the sun because UV radiation might harm them.
