Three properties north of Adelaide have destroyed produce worth millions of dollars since being quarantined in August, after tomato brown rugose fruit virus, known as ToBRFV, was detected on their properties.
It has been contained to the three properties, with no further detections reported, Greenlife Industry Australia says.
The eradication plan includes measures such as surveillance, testing and strict hygiene protocols to protect the production and trade of tomatoes and capsicums.
The containment is a positive development, but vigilance remains crucial, according to John McDonald, director of Research, Development and Extension and Biosecurity at Greenlife Industry Australia.
"By acting decisively and adopting precautionary measures, we can safeguard the horticulture industry and ensure its continued contribution to Australia's economy and food security," he said.
He warned of the potential consequences if ToBRFV was not eradicated.
"A widespread outbreak could result in significant trade disruptions, including export restrictions and regulatory challenges, as well as damage to Australia's reputation as a trusted supplier of high-quality greenlife products," Mr McDonald said.
The tomato industry is worth $230 million in SA and $800 million nationally, while the wider production nursery sector is worth $2.78 billion annually.
The eradication effort, led by the South Australia Department of Primary Industries and Regions, is being nationally cost-shared by governments and industries, including Greenlife Industry Australia.
Biosecurity protocols such as enhanced hygiene and surveillance were essential for protecting nurseries and ensuring long-term resilience against emerging threats such as ToBRFV, Mr McDonald said.
The virus spreads easily via infected seeds, plant material, human contact and tools.
"Production nurseries must prioritise strict hygiene and monitoring measures to prevent further outbreaks and safeguard the supply chain," Mr McDonald said.
Greenlife Industry Australia recommends production nurseries adopt robust biosecurity measures, including enhanced hygiene protocols, frequent monitoring, safe sourcing of seeds from certified, disease-free suppliers and cross-contamination prevention.
