Tree-Ject - a portable hand-operated pressurised tree injector for pesticide and nutrient application.
Abstract
The novel technique of direct placement of chemicals by stem injection has prompted the recent invention of a light, portable pressurized injector aimed at replacing the non-pressurized ordinary plastic syringes or spring-loaded plastic syringes used to-date. The new manually operated injector that is carried as a backpack during field use is described. It is constructed of metal, comprising a small-sized nozzle in front of a short longitudinal chamber connected to 2 handlebars. For injection, handclasping once to draw in a fixed amount of the liquid chemical, followed by that of a return outward action, forcefully discharges the chemical safely into a small, shallow hole pre-drilled into the outer wood of the tree stem or trunk under treatment. Its introduction will help speed up adoption of the more sustainable method of chemical stem injection on plantation trees under integrated pest management, in place of the conventional spray or soil drench.
