ABSTRACT:
A plant duster, especially for data palm pollination, has a small tube for dispersing dust and a container for the dust to be dispensed. A rubber stopper in one end of the container and about one end of the small tube flexibly mounts the small tube on the container for communication with the container for receiving the dust. A truncated, hollow cone has one end on the other end of the container for communicating with the dust therein and a threaded tube on the other end. A first carrying tube section is threaded on to the threaded tube at one end and has an enlargement about the other end. There are also further carrying tube sections in graduated diameters, each further carrying tube section having an enlargement about one end corresponding to that about the other end of the first carrying tube section and an expandable connection about the other end for releasibly receiving the enlargement of another carrying tube section. A last carrying tube section has an expandable connection corresponding to those of the further carrying tube sections on one end and threads on the other end. A tubular, battery-operable air pump has threads on one end for connection to the threads on the last carrying tube section for pumping air through connected carrying tube sections to the container, whereby to entrain the dust therein and dispense the entrained dust through the small tube.
