Chapin 64800 4 Gallon Backpack Sprayer Garden Pest Weed

Product Description

The CHAPIN 64800 is a 4-gallon backpack sprayer built for professionals and serious users handling fertilizing, weed and pest control, fungus control, wettable powders, and general purpose cleaning. The tank is constructed from polyethylene and paired with a reinforced hose rated to 60 psi maximum operating pressure. A brass adjustable nozzle delivers a cone spray pattern with consistent coverage across a wide range of liquid chemicals and dry wettable powder formulations. Three included nozzle tips extend versatility across different application types. Padded shoulder straps and lumbar support allow extended wear during large-area treatments. A cushion grip poly shut-off valve gives the operator immediate spray control in the field.

This sprayer is suited for residential and light commercial outdoor applications including lawn and landscape maintenance, nursery work, pest control routes, and agricultural plot management. The 20-inch wand provides reach for low-clearance shrub and turf applications. The 4-inch opening diameter on the tank simplifies filling and allows powder mixes to dissolve before application. An in-tank filter reduces nozzle clogging when using wettable powder or suspension formulations. This unit is appropriate for licensed pesticide applicators, landscape maintenance techs, and property managers handling routine chemical applications.
