Turn the hand crank and the Dustin Mizer Applicator disperses a steady and even flow of dust from its 16in tube. Leaves are blown by the air coming out of the wind tunnel and become covered with dust on both sides. Use to apply insecticidal or organic dusts such as Diatomaceous Earth to gardens, lawns, beds, orchards and more. Non-corrosive and chemically inert plastic and steel construction will last for many years. Holds 1 lb of powder. Made in the USA.
