Tips

  • A backpack sprayer’s nozzle can produce a variety of droplet sizes, including very fine, fine, medium, coarse, very coarse, and extremely coarse. The sprayer should indicate what size droplets should be applied. If the droplets are too fine, they will drift. If they're too coarse, they will not spread far enough for an even distribution.
  • Choose a product that is comfortable so that you don't get fatigued while completing your work. Many backpack sprayers have an adjustable and padded waist, shoulder, and chest straps.
  • Properly maintain your backpack sprayer so that it operates efficiently and lasts a long time. Make sure to wash it after every use with either water or a commercial cleaner. Also, lubricate the seals and o-rings at least once a year.

FAQs

Q: Is it better to use a sprayer with a motorized pump?

A: It depends on how much work you need to do. If you only spray your weeds a few times a week for 15-20 minutes, a motorized sprayer isn't necessary. However, it makes the job easier.

Q: What is the best spray pattern to use? 

A: A backpack sprayer's wand has a nozzle that can produce many patterns. Most people prefer using an even flat-fan pattern for single-nozzle applications. Other patterns include extended flat fan, full cone, hollow cone, and flood.

Q: What is the ideal PSI for a backpack sprayer?

A: Read the instructions on your sprayer so you know how to calibrate it properly. Typically, a pressure between 20 and 60 psi is fine, but some sprayers offer much more than that. The aim is to have as little drifting as possible while maintaining accuracy and a uniform pattern.
