The best backpack sprayer for weed killer depends on how much you need to spray and how often. For smaller jobs - covering up to 100 square metres and occasional use, the IK12 knapsack sprayer is an excellent choice. It’s affordable, well-built, and simple to set up. With a 3-bar spray pressure, it supports useful accessories like multi-nozzle spray booms and lance extensions, making weed control easier and more efficient. The IK12 is also compatible with other chemicals like moss killers and surface cleaners, offering great versatility.
For larger areas - over 100 square metres or frequent weed spraying, the RS12 or RS18 backpack sprayers are ideal. These models offer robust build quality and hold up to 18 litres of solution. With a powerful 6-bar maximum spray pressure (double that of the IK12) they outperform most manual backpack sprayers, delivering superior coverage and performance.
