DEPARTMENT OF PRIMARY INDUSTRY AND FISHERIES BARKLY BEEF | page 5 www.dpif.nt.gov.au collected GPS points. Graham then made the area surrounding the point into a polygon shape that plane could fly over in parallel lines as seen in Figure 1. Ken supervised loading the plane with one tonne of tebuthiuron that had been trucked down from Katherine. Once the plane was loaded, everyone headed out to the site to watch the plane distribute the chemical at 12.5 kg per hectare. The pilot, Brett, was practical in his approach ensuring he had good coverage of the infestation. He visually assessed the infestation from the air before dispersing the herbicide. While the photos dont show the tebuthiuron being released, the granules can be clearly seen on the ground following application. Trials were also undertaken at Brunette Downs at two sites containing rubber bush. A representative from Dow Agro Sciences will return next year in May to visit both stations to determine the efficacy of the aerial trials with Weed Management Branch staff. On ground control trials, also being undertaken as part of the MLA project are starting to yield results, but next year there will be more conclusive information about the top performing chemicals in controlling rubber bush under Barkly conditions. A field day planned for April/May next year, to be run in conjunction with Naomi Wilson from Territory Natural Resource Management (TNRM), will showcase results and determine future rubber bush management opportunities in the Barkly. The DLRM Weed Management Branch is grateful to AACo and S. Kidman & Co, their Managers Michael Johnston and Chris Towne, and their Assistant Managers Steve Pocock and Luke Giblin, for their involvement in the trials and for showing leadership in trialling this promising management technique. The Branch would also like to acknowledge project partners Charles Darwin University, MLA and Queensland Governments Department of Agriculture, Fisheries and Forestry, and in particular Shane Campbell.
