Fungal diseases impacting tree species – What can urban Arboriculture learn from horticultural tree cropping?

Elizabeth Dann, Associate Professor from University Queensland will be presenting this Live webinar via Microsoft Teams.

Date: Tuesday 23 February 2021.

Time: 8.00 am – 10.00 am.

The presentation will focus on the two following topics:

  • Soilborne and foliar fungal diseases
  • How to manage them

Following these presentations will be a Q & A.


About Liz:

I did a BScAgr at University of Sydney and enjoyed completing an independent research project in plant pathology during my last semester. I went straight onto a Ph.D. in the same lab, investigating the natural defense mechanism in plants, using green bean as a model host. I had 2 years at Michigan State University in the USA, looking at induced resistance to diseases in soybean, and returned to Sydney working on various projects. I moved to Brisbane in 2001, joined the fruit pathology team at DPI (now DAF) and switched to research on diseases in tropical and subtropical crops, mainly mango and avocado, juggling part-time work with raising a family.


What Liz is currently working on:

The Queensland Government and University of Queensland set up a new institute within UQ, QAAFI (Queensland Alliance for Agriculture and Food Innovation) in 2010, so I joined UQ but remained located with my DPI/DAF plant pathology team.  I lead the pathology and disease management projects for the avocado industry (funded by Hort Innovation, using the avocado R&D levy).  The research is very applied and covers all diseases of avocados. It takes me into the field and nurseries a lot for research trials and also diagnostic work, ie. helping growers with disease or other orchard issues. There is more flexibility within UQ, so my team frequently complete short consultancy projects, which can also lead to very rewarding outcomes for industry.  I supervise students for postgrad (eg. masters and Ph.D.) and also short undergrad research projects.


Why Liz is passionate about this topic:

I have a lot of direct interaction with industry, getting out in the field for research trials and learning first-hand what the main production issues are for growers. I enjoy presenting my team’s research to industry to show them how they can take steps to improve their productivity or fruit quality. I have to acquire knowledge in areas outside of my training, eg. plant physiology, soil science, marketing, and this all helps me to put our specific research outputs into an overall management plan.  I also enjoy mentoring staff and students.


Liz’s goal for this webinar:

I hope the participants will appreciate all of the complex pathogens and factors facing long term tree cropping, and I hope I can highlight some of the common problems affecting trees, whether in city parks or gardens, or commercial orchards. Many of the management strategies or approaches are likely to be similar.

About the Presenter:

Katia Plouznikoff is a soil biologist specialised in soil microbiology applied to agronomy. She works as an agronomist for Costa Avocados and has a fondness for mycorrhiza and plant biotechnologies. She has worked on several research projects aiming to sustainably improve crop cultures with the help of beneficial soil microorganisms. Thus Katia has spent long hours over a microscope looking at such microorganisms living in the rhizosphere, but what she likes the most is to inspect sites armed with her favorite tools such as: penetrometers, auger, moisture probes, pH probes, EC probes and Brix refractometers to conduct soil investigations for tree surgery, assessing tree and soil conditions, and performing soil sampling to establish soil chemical and physical profiles.

As an agronomist Katia carries out plant tissue analyses to investigate poisoning, contamination and nutrient deficiencies. Interpretation of soil tests and analyses combined with literature research allowed her to previously develop and implement biotechnologies for plant health care treatments such as microbial brewed compost and active mycorrhizal inoculum.

Katia is willing to share her knowledge to increase tree survival rates and promote a better tree management with sustainable organic practices to help make our environment greener.

Janet McDonald 
Forest Health Surveillance, Forest Production & Protection Horticulture & Forestry Science

Department of Agriculture and Fisheries

Janet will be presenting her Pest and Disease Damage & Symptom Recognition Workshop. 

**Attendees will receive copies of Booklets: Forest Health Surveillance Damage Recognition & Forest Health Surveillance Collection Techniques.

Janet McDonald has been working with the Department of Agriculture, Forest Health Surveillance (FHS) team since 1998 conducting pests and disease surveys in forestry plantations throughout Queensland. Janet was part of the team of researchers who set up FHS systems in the South Pacific Islands and most recently in south-east Asia. She was responsible for establishing FHS systems in the sandalwood plantations in the Ord River Irrigation Area near Kununurra WA. After twenty years of experience conducting pest and disease surveys and collecting samples in the field, Janet is now looking forward to sharing her knowledge with industry professionals.

“Quite often the agent causing the problem will have been and gone but it’s the symptoms they leave behind that are important.”
“Damage to a tree can be occurring underground but the symptoms are showing above ground. You just need to know how to recognise them”.
“Simple techniques can be used in the field, for example, knowing the difference between chlorosis caused by toxicity or nutritional disorder”.

Types of damage:
Leaf chewing
Gall-forming – insect & fungal
Leaf tying
Stem/branch boring
Leaf pathogens
Root pathogens
Nutritional disorders
Exotic/biosecurity agents

Field identification – “Some types of damage are specific to a particular agent which makes the problem identifiable in the field”

Field sample collection techniques and photography – “You could have the best sample in the field but if it’s not collected correctly it’s useless for identification”

Field equipment hygiene – “It’s important to practice field hygiene so that you’re not spreading the problem”
