Giant Rats Tail (GRT) fundamentals and insights for management.
Understanding basic Giant Rats Tail (GRT) grass biology enables landholders to develop clear management strategies that will assist them in reducing its impacts and maintaining productivity of grazing land.
Relying solely on a single management tool such as herbicides will not achieve satisfactory outcomes.
In this presentation Dr Wayne Vogler (Senior Weed Scientist, Biosecurity Queensland) discusses the requirements of an integrated management approach which includes all aspects of pasture management to maintain a productive pasture if the negative impacts of GRT are to be kept to a minimum.
