A key research focus of the Centre for Crop Health is management of soil-borne and foliar diseases of crops using genetic, genomic, phenotypic and pre-breeding approaches. The aim of our projects in this area is to reduce the economic impact that these diseases have in Australian farming systems and to broaden the scientific knowledge of the causal agents, including crop pathogenic fungi, bacteria, nematodes, and viruses and viroids

Title: National Variety Trials (Pathology) 2019 - 2024
Project Team: Dr Jason Sheedy | Dr Cassy Percy | Associate Professor Anke Martin
Project Partners: | |  Plant Breeding Companies
Funding Body:

The National Variety Trials (NVT) program is the largest independent co-ordinated trial network in the world. The program assists Australian grain growers in varietal decision making by providing comparative information of commercially available grain varieties, including: yield performance, disease resistance ratings, and grain quality.

Screening the field tolerance and greenhouse resistance reactions of nominated CAIGE Bread Wheat lines to the root lesion nematode Pratylenchus thornei. 

Title: Mechanisms on resistance towards DMIs in grape powdery mildew
Leader: Professor Levente Kiss
Project Team: Dr Sadegh Balotf
Project Partners:  
Funding Body:  BASF

The aim of the project is to determine the sensitivity or resistance levels of grape powdery mildew populations to DMI fungicides in Australian vineyards.

Title: Australian Fungicide Resistance Extension Network (AFREN)
Leader: |
Funding Body:

AFREN has been established to develop and deliver fungicide resistance resources for grains growers and advisers across the country. It brings together regional plant pathologists, fungicide resistance experts and communications and extension specialists. A team at CCH, led by Prof Kiss, is a partner of AFREN.

An integral part of our research at the Centre for Crop Health is improving crop disease management through better understanding the genetics, genomics, biology, and infection cycle of crop pathogenic fungi, nematodes, and bacteria. At CCH, we use a range of traditional plant pathology techniques and state-of-the-art genomic tools to enhance knowledge of the biology of crop pathogens, which can be directly translated into reliable and durable disease management recommendations at a paddock level.

Title: My enemy’s enemy is my friend: The genetics of major plant pathogen killers
Leader: Professor Levente Kiss
Project Team: Dr Alexandros Georgios Sotiropoulos | Dr Sadegh Balotf
Project Partners: |
Funding Body:

Fungal plant pathogens are often parasitized by other fungi in the field. The project will focus on these interactions between powdery mildews, important pathogens of many crops and wild plants, and their common fungal parasites, known as mycoparasites, that have already been utilised as biocontrol agents in crop protection. Genetic and genomic tools will be used to determine what makes these mycoparasites uniquely capable of suppressing powdery mildew colonies in the field. The project has the potential to establish new innovative methods to protect a wide diversity of crops from powdery mildews using mycoparasites or specific compounds derived from them.

Title: Novel biological and genetic disease control tools for the barley industry
Leader: Associate Professor Anke Martin
Project Team: Dr Buddhika Dahanayaka
Project Partners: | | Queensland | Plant Breeding Companies
Funding Body: 

If left unmanaged, foliar diseases of barley can result in >35% annual grain yield loss in years suitable for disease development. The plant-microbe interactions involved are usually genetically complex, making breeding for resistance challenging. This ARC Linkage project will develop knowledge, tools and biological resources for the Australian barley industry that will expedite the production of disease resistant barley varieties against net form of net blotch.
