Chapin 61900 4-Gallon Tree and Turf Pro Commercial Backpack Sprayer Review

In this review of the Chapin 61900 Tree and Turf backpack sprayer, we’ll take a look at what types of chemicals it can hold, feedback from users on the durability, ease of use and comfort of this 4 gallon backpack sprayer.

The Chapin 61900 is designed to work with pesticides, herbicides, fungicides and weed killers.  It is the most popular of the Chapin backpack sprayers for this type of use.

You cannot use this sprayer for bleach.

Backpack sprayers are far more comfortable and efficient than carrying around a hand sprayer.

So what are the key differences between the 61900 vs 61800 as they are both herbicide and insecticide sprayers?  They are both 4 gallon backpack sprayers but the 61900 can take fungicides and has a stainless steel wand that will last much longer.

You can read lots of reviews on the Chapin 61900 on this page of Amazon.

Note: As with all sprayers, you never leave chemicals in the tank.  You must empty it out, rinse and flush clean water in the tank and through the wand.
