Our rose duster is a quick, efficient way to apply pesticide, fungicide or fertilizers. The 16 ounce translucent bottle has a large opening for easy filling and cleaning. It's lightweight, making it easy to use in nurseries and smaller gardens. 'Snorkel' tube and dual orifice seal agitates the contents and provides a nice, uniform dust cloud and allows the duster to stay in optimal orientation for powder concentration. Adjustable position, fan tipped nozzle to help direct the dust cloud to the underside of leaves, petals and other hard to reach places.
