key weed species

The project will address regulatoryrequirements as well as determine the most efficient and efficacious methods of controlling weeds of the Australiangrains industry... The project will proceed in two phases... Studies will include assessments on OH&S; radio frequencyinterference by the microwaves to other equipment used on or around farms and adherence to Australian andInternational Standards and legislation involving the use of microwave technologies...

DAF is seeking permission from growers and land managers to enter properties to collect weed seeds, and will conduct two surveys in Queensland coinciding with winter and summer grain and legume harvests... Weeds targeted in the survey include feathertop Rhodes grass, fleabane, sowthistle, barnyard grass, windmill grass, liverseed grass, annual ryegrass wild oat and Brassica species if present... In Queensland, growers will be contacted prior to paddock visits with a date and an estimated time of visit, and both QDAF and CSU personnel will ensure extra care is taken to make sure boots and clothing are free from weed seeds before entering property...

Results from the study indicated that karrikinolide may be an efficient means of stimulating weed seeds to germinate... Results from the study provide insight into karrikinolide's mode of action, in that karrikinolide appears to be working as a germination stimulant rather than a dormancy breaking agent... Future research and development opportunities associated with karrikinolide involve expanding our knowledge in three key areas: (1) karrikinolide responsive species (2) optimising efficiency of karrikinolide application and (3) karrikinolide mode of action...

Highly respected throughout the Australian weed scientists' community, the team conducts valuable research into best-practice weed management for central and southern Queensland agriculture, weed ecology and the safe use of herbicides in crops... Over the past decade, the team has quantified risks associated with the development of herbicide resistance in weeds of the northern grain region, and has made recommendations for avoiding and managing weed populations resistant to important herbicides... Unlike previous models produced in other parts of Australia, the model enables simulation of a wide variety of weed species, agronomic practices, and weed control tactics, to help understand and explain the impact of agricultural decision making on the rate of evolution of herbicide resistance...
