Held Wednesday 22 June 2022

With the harvesting and processing olive season coming to an end for many growers around Australia, it is an ideal time to be considering bottling and storage considerations of EVOO.
  • What can affect the shelf life of EVOO?
  • How do you determine the best before date of your EVOO product?
  • What are the labelling requirements regarding best before dates?
These questions and more will be covered in this webinar on EVOO shelf life prediction. Presented by Claudia Guillaume.

Webinar – The Mediterranean Blessing, Olive Leaf as a Herbal Medicine

Held Tuesday 5 July 2022

Whilst we all know that the fruits of the olive tree have been used as a food for millennia, many don’t know that the leaf has also been used for hundreds of years as a medicine. An article in the Pharmaceutical Journal in 1854 discussed its use in fever caused by infections, and modern research indicates it may be beneficial in reducing the risk of diabetes, diseases of the blood vessels, and improving immune function. However not all olive leaf products are equal.

This webinar will briefly discuss the medicinal value of olive leaf extracts, and present important research on how extracts made from fresh versus dried leaves can be quite different.

Webinar – Polyphagous Shot-Hole Borer in WA

Held 16 August 2022

A new and emerging threat at the urban forest-residential interface.

Presented by Dr Kylie Ireland, Plant Pathologist, DPIRD Plant Biosecurity Pest Risk & Analytics Team.

Polyphagous Shot-Hole Borer (PSHB) has a symbiotic relationship with a Fusarium fungus, cultivating it inside the tree as a food source for the beetle and its larvae. In susceptible trees, the fungus kills vascular tissue causing Fusarium dieback and tree death.

Establishment of this pest would have significant impact on amenity trees, native vegetation, and the fruit and nut tree industries.

This presentation will summarise response activities, explore some of the challenges and opportunities present at the urban forest-residential interface, how these are being navigated and how stakeholders can help us in the fight to detect and manage PSHB.

She loves plant biosecurity, the science-management/policy nexus and agricultural extension. With a PhD in plant biosecurity from Murdoch University, Kylie has worked on a diverse range of projects, including pest risk modelling, Myrtle rust ecology, plant pathology capacity building in Laos, plant pest impacts, weed biocontrol and fungicide resistance extension. Kylie is a director of the Australian Plant Biosecurity Science Foundation and leads the editorial team of the APPS Newsletter.
