Ongoing project
Better understanding of papaya phytophthora rot (PP23001)
Delivery Partner: RMIT University
This project aims to understand and manage Phytophthora, a destructive disease affecting papaya crops by improving detection, management practices, and overall production.
Challenge
Phytophthora species pose a significant threat to papaya production in Australia, thriving in humid conditions and causing severe crop damage. Traditional management methods, including cultural practices and fungicides, often fail to control the disease effectively. The challenge lies in accurately detecting and quantifying the pathogen to develop better management strategies.
Response
In response, the project will leverage innovative technologies like real-time PCR and lateral flow devices to detect and breed Phytophthora-free papaya strains. By consulting stakeholders and analysing existing data, the project aims to fill knowledge gaps and devise efficient disease management strategies. The team will disseminate findings through industry extension materials and workshops, empowering farmers with sustainable practices.
Benefit
The project's findings will provide a deeper understanding of phytophthora, improved disease detection and quantification, potential genetic-based management solutions, and enhanced industry profitability and sustainability. By sharing knowledge and best practices, the project will empower growers and contribute to the long-term viability of the papaya industry.
