Best Backpack Sprayer – Buyer’s Guide 

Shopping for the best backpack sprayer can be an intimidating task, but this short buyer’s guide will highlight all of the important things you want to consider when you start comparing products. If you get stuck between one or two, these buying considerations will help you make your final choice. 

Size

How much space do you want to cover with your new best backpack sprayer? For example, do you have a few low-maintenance landscapes dotted around your yard or do you plan to have a massive garden? The best backpack sprayer should be able to accommodate whatever type of area you have to cover without you running out midway through. Some come with the capability to hold up to two gallons while others can hold four. The size will also dictate the weight when it’s full too. 

Smaller backpack sprayers are nice to have if you only have a few pots or a small yard to cover. However, you’ll need a larger setup if you want to spray a big yard or garden without having to stop halfway through.

Backpack Sprayer Type

Generally speaking, there are three broad categories for your backpack sprayer. Choosing one from the start can help narrow down your options straight away. They include: 

• Battery – Battery-powered sprayers have Lithium-Ion batteries in them for the power source. They’re very portable and powerful machines, but they tend to be both more expensive and heavier than hand pump models. They’re also better-suited for smaller areas as the battery can die after a few hours. 

• Gas – This type of pump is very effective and powerful when it comes to moving a lot of liquid in a short amount of time, but they’re also more expensive and heavier. They require maintenance and regular fuel additions to run too. However, they give you the power that you can’t get with the two other models. 

• Hand Pump – Hand pump-style sprayers build up water pressure as you operate the pump by hand. These are very simple machines with several benefits, including being more affordable and lighter than the battery or gas-powered models. They’re also usually very environmentally-friendly, but you have to put a little more work in to get them to run correctly. 

Wand Length

Sprayer wands vary in length from 12 to 48-inches, and some are extendible. You want to think about how high or far away from you that you have to reach when you use it. If you have hanging baskets that are just over your head, you won’t need as long of a wand to reach. But, if you have large planter boxes, you’ll need your best backpack sprayer to have a longer wand to reach every corner. Also, consider the nozzles you need. 

Ergonomics 

Ergonomics is how comfortable your best backpack sprayer is when you put it on and it’s full. To increase your comfort levels, look for padded shoulder straps. Some larger models also come with waist straps and lumbar support to protect your back. Look and see how far the values and wands are from your natural reach because this will give you a good idea on how far you have to twist and turn to use it. 

Weight

You really want to consider the weight factor on your backpack sprayer since you’re going to carry it around for up to several hours at a time. It should have a comfortable fit with padded straps to help keep you comfortable. You also want it to be well-balanced, and take into account how large the tank is because the liquid can add a huge amount of weight when you fill it.

PSI

The PSI is the pressure of the spray on your best backpack sprayer. The higher the PSI is, the further and wider the spray will be when you use it. The PSI can range from 50 up to over 150, and some backpacks come with an adjustable knob that allows you to tailor your PSI to your particular plant or flowers. More delicate flowers like Amaryllis will need a lower PSI while more hardy plants can stand up to higher PSI ratings. 

Cost 

You should set a budget when you start to shop for your backpack sprayer so you don’t fall in love with a model that is out of your price range. The costs can vary from $50 up to over $150. So, try to find a model that fits into your budget and that is big enough to cover your area. 

Getting the best backpack sprayer can help you treat and protect your crops to ensure you have a large harvest in the late summer and early fall. 

Bottom Line

The best backpack sprayers can help streamline the process when you fertilize or apply pesticides to your garden or yard. I’ve listed 10 great options for you, and you can compare the reviews side by side. The buying guide highlights the important factors you want to consider when you shop, and this will help you pick out the best backpack sprayer to suit your wants and needs.
