The Chapin Wet/Dry Hose-end Sprayer is an efficient sprayer made for spraying pesticides and fertilizer. Water-soluble or liquid gardening chemicals can be used. It mounts to the end of a standard garden hose and mixes the desired amount of chemical and water. The sprayer also has an anti-siphon feature that keeps the water source clean from any dirt contamination. Also, when the hose connection are switched on or off, small amounts of water can be sent to the end of the link by using the dial.
