Duster

a machine or device for applying powdered dry pesticides to crops to protect them against pests and disease. Tractor-mounted or knapsack manual dusters are used, depending on conditions.

Tractor-mounted dusters are used to dust field crops, orchards, vineyards, and forest tracts. The working members are driven by a power takeoff shaft from the tractor engine. The operating width depends on the design of the duster; for vineyards it covers two to four rows, and for field crops, 10–100 m. Rated performance is from 3.5–5.0 to 30–64 hectares per hour.

Knapsack dusters are used to treat vineyards, young fruit plantings, berry patches, vegetable fields, and other crops on small and inaccessible plots. The main units of such a duster are a tank with a feed device, a fan with a drive handle, and a tube with a spray nozzle. It has shoulder straps for carrying. Some knapsack dusters have a bellows instead of a fan for spraying the pesticide.

All dusters have the same principle of operation. The powder is fed from the bin or tank into a mixing chamber, and then it is forced by a stream of air created by the fan or bellows through the spray nozzle and out onto the plants.
