<p>The invention relates to a spraying apparatus (10) for spraying trees and plants that have a foliage canopy. The invention broadly resides in a spraying apparatus (10) that includes a fan within a fan housing (12), a ducting assembly (11) mountable adjacent the fan and adapted to receive air from the fan wherein said ducting assembly (11) has an upper duct outlet (17) upwardly spaced from the fan and a lower duct outlet (18) laterally spaced from the fan, and a spray supply means including spray nozzles (19) for providing ducted air with spray. In a preferred embodiment of the invention the ducting assembly (11) has a plurality of ducts wherein each of the ducts has an internal expanding passage extending from a duct inlet to a duct outlet (17, 18). The duct inlet is preferably adjacent the perimeter of the fan so that air is forced directly into the duct inlet with minimum turbulence.</p> |
