4 Best Backpack Sprayer for Controlling Weeds

Are you trying to protect your plant from pests and weed? If you’re growing some plants in your backyard, you’d want to take care of the surroundings in which your plants are growing in. To do this, you’d need to get a backpack sprayer as it’ll help in killing weeds and destroying pests efficiently and effectively. If it’s your first time purchasing a backpack sprayer, you could be overwhelmed by the sheer number of backpack sprayers on the market.

A Closer Look to Backpack Sprayer

Here, we’ve rounded up 4 of the best backpack sprayers. Before we delve into the details, here are some features you should take note of when selecting your backpack sprayer.

First, you need to consider if you’d like a backpack sprayer with a motorized pump. If you’re spraying for more than an hour every single day, a motorized pump will help you with your task. If you’re only doing it for less than an hour sporadically during the week however, you won’t need one. A motorized pump helps with maintaining pressure, flow rate, and spray quality with minimal effort. They can be a fair bit more expensive than manual sprayers however, so you should consider if you need to invest in a motorized pump.

Then, you’d need to think about the spray pattern and quality. Do you prefer for the solution to flow out in a single stream or to be broken up into tiny droplets? Most individuals tend to go for flat-fan spray patterns. In regard to spray quality, you’ll have to consider the size of the droplets that are coming out of the nozzle. Usually, the product you spray your plants on will tell you what size the droplets should be.

Finally, there’s the consideration between diaphragm and piston pumps. The decision is simple. If you’re using a spray solution that has particulate matter, you’d want to consider a diaphragm pump. If you’re using liquids however, the piston pump would work better for you. The reason being, if you use a piston pump for a solution with the particulate matter you risk producing friction which will eventually lead to rapid wear and tear.
