This guide is aimed at showing the best backpack sprayers. Backpack sprayers have made the job of spraying your garden with herbicide easier and faster. If you are interested in getting one for your gardens, read through this guide for all you need to know concerning getting yourself a backpack sprayer.

The backpack sprayer mounts to your back, and all you need to do is walk around and spray your yard or vegetable garden. The backpack system takes the effort out of your work, allowing you to treat your garden in a matter of minutes.

It helps your spray down your plants easily and efficiently. Carrying around a manual pump sprayer is a hassle, and may result in injuries, especially in older gardeners. A backpack sprayer lets you spray down the entire garden, without experiencing any operator fatigue.


Manual or Battery Operated

Backpack sprayers come either battery-operated or manual. The manual versions require pumping to produce the pressure needed to get the liquid out of the container. Battery-operated devices use a motorized pumping mechanism.

Motorized versions are often more convenient and easier to use for bigger areas. Of course, you do have to charge them before you use them. Also, they may take more maintenance to keep them in good condition and working properly.

Manual sprayers use a lot more effort from you, but they are ready to go at a moment’s notice. They can be less expensive than motorized versions. Also, these sprayers rarely need much maintenance to keep them up and running.

Sprayer Tank Capacity

The amount the sprayer can hold is important. If it’s too heavy, you aren’t going to be comfortable. If it doesn’t hold enough, you’re going to have to stop frequently for large jobs.

Determine what you’re spraying and where to figure out the size tank you require. That way, you’re comfortable while outside.

Pump Type

The pump is essential to get the liquid out of the sprayer and through the nozzle to go where you need it. You’ve got piston and diaphragm pump sprayers.

The piston pump is often cheaper than the diaphragm option. However, it might be less durable if you tend to use dry formulations. Diaphragm pumps are a favorite among consumers because they’re easier to maintain and offer more durability.

Chemical Rating

Many herbicides and other chemicals are corrosive. Therefore, you should pick sprayers that are designed to handle those chemicals. Remember to make sure that the unit’s seals, hoses, and all accessories are rated for herbicides if that’s how you’re going to use the equipment.

Safety and Comfort

Safety and comfort are essential when choosing a backpack sprayer. Some sprayers feature a full-size handle, padded straps, and a gentle grip for the wand. These are all designed to increase your comfort.

They also help reduce fatigue and your risk of exposure to chemicals. The tank is contoured, as well, which makes it easier to sit across the back. Plus, the harnesses are adjustable, which allows you to make it fit your particular body.

High-density polyethylene is the best material for a sprayer. That way, it protects from UV exposure. This means that the contents aren’t going to get heated and risk combustion or degradation.

Maintenance and Repair

Of course, maintenance is essential. Most of the time, you just take off all the accessories and rinse them off. Then, you can put it all back together.

Therefore, you’ve got to make sure that it’s easy to maintain. Repairs may also be needed at times. Make sure you can get the parts you need and find it easy to do it yourself.

Straps and Lumbar Support

Most backpack sprayers are manufactured to carry four gallons of liquid. Using rough numbers of approximately 8.5 pounds per gallon, this calculates to carrying about 34 pounds of liquid on our backs.

Add in the weight of the sprayer itself, and you could be looking at carrying around nearly 50 pounds on your back! Proper straps and lumbar support are of great importance when you are working with this type of weight on your back.

An important feature to be on the lookout for is a waist strap. While simple shoulder straps work well for light packs, backpack sprayers demand better control and a comfortable fit for long hours spent spraying.

A waist strap will help to distribute the load across your hips. This will give you better control of the sprayer, as well as share some of the load from the shoulder straps.
