TAS Country : March 29th 2012
Friday, March 30, 2012 Tasmanian Country 11 Tea tree oil kills maggots, lice KAROLIN MacGREGOR Tea tree oil being harvested in northern New South Wales could be the new weapon in the fight against fly strike TEA tree oil could be a valuable tool in the fight against fly strike and lice in sheep, according to new research being done in Queensland. A study by the Rural Industries Research and Development Corp- oration has found that tea tree oil can effectively kill lice and blowfly maggot larvae. Queensland Alliance for Agriculture researcher Peter James said laboratory trials had shown that a 1 per cent tea tree formulation produced a 100 per cent kill rate of lice and lice eggs. ''We were very pleased to see that our pen trials generated the same results,'' he said. Sheep in the trial were carefully inspected at two, six, 12 and 20 weeks after shearing and being dipped in a 1 per cent tea tree formulation and at all points, no lice were found in the wool. As part of the research sheep with longer wool were also jetted with 1 and 2 per cent tea tree formulations, which reduced louse numbers by 94 per cent two weeks after the treatment. The study has also found that tea tree oil can effectively kill first stage maggots. A 1 per cent tea tree formulation was used and produced a 100 per cent maggot larvae kill rate. Mr James said the formulation was also found to be a strong repellent for adult flies, which prevented eggs being laid on the wool for up to six weeks. ''Tea tree oil could be effective as a preventative treatment for wounds caused by mulesing, tail docking or any wound that may be struck,'' Mr James said. ''It has also been shown to have antibacterial properties and is suggest- ed to have wound-healing effects.'' While tea tree oil was appealing as an insecticide because it is a natural product, Mr James said more research was needed to get the right formulations. ''It's not as simple as mixing tea tree oil with water and applying it.'' News IT S NOT JUST A FENCE. IT S A FENCING INNOVATION.
