The Gilmour Dial-A-Mix is designed to make mixing solutions a cinch for garden use. Use the dial to select the mixing rate in teaspoons, tablespoons, or ounces per gallon to mix chemicals automatically as you spray. The Dial-A-Mix affixes to your hose to spray up to 132 gallons of finished spray per filling, spraying up to 30 feet. Unused chemicals can be returned to the original container for future use. An adjustable deflector allows solid-stream spray or a gentler, rain-like spray for milder applications.
