Title: What can modelling with A-TEEM data tell us about grape and wine traits?
Abstract: This presentation will introduce the approach of absorbance-transmission and fluorescence excitation-emission matrix (A-TEEM) spectroscopy and highlight how we use that to undertake grape and wine research. Examples will include authentication of red wines, including wine classification at a sub-regional level, as well as prediction of grape maturity indices and sensory scores from grape and wine spectral data. The latter aspect presents somewhat of a holy grail in wine research, being able to forecast the sensory properties of wines using chemical methods of analysis in place of human panellists.

Title: Reimagining weed management in the grains industry: The GRDC Weed Management Initiative
Abstract: The GRDC Weed Management Initiative (WMI) is a 5.5 year and $47 million investment led by GRDC and developed to support Australian grain growers to manage one of the most persistent and costly challenges facing farming businesses. The WMI is established as a set of 4 collaborating nodes across Australia. The University of Adelaide hosts the node in the GRDC Southern Region. Weeds cost grain producers across Australia about $4.1 billion per annum in lost production and control costs. In addition, the increasing incidence of herbicide resistance is increasing the complexity and cost of managing weeds. This presentation will cover the role the University of Adelaide will play in the WMI and the research activities that will be conducted to address this problem.
