R&d update: Australia launches $5M plan to eradicate tomato brown rugose fruit virus

The Australian horticulture industry has mobilised a $5 million eradication effort following the detection of tomato brown rugose fruit virus (ToBRFV) in South Australia’s Northern Adelaide Plains. This coordinated response aims to eliminate the highly transmissible virus and protect Australia’s $2.78 billion production nursery sector.

First detected in August 2024, ToBRFV affects tomatoes, capsicums and chillies, causing deformities, reduced yields, and diminished fruit quality, posing a significant biosecurity threat. The virus is currently contained to four linked properties, with no further detections reported. John McDonald, Director of RDE and Biosecurity at Greenlife Industry Australia (GIA), emphasised the importance of rapid action.

“The $5 million eradication plan is critical to securing the horticulture sector. Containment to three properties is promising, but vigilance is essential,” Mr McDonald said.

“By acting decisively, we can safeguard the industry’s contribution to the economy and food security.”

If unchecked, a widespread outbreak of ToBRFV could lead to severe trade disruptions, export restrictions and reputational damage to Australia as a supplier of high-quality greenlife products. To prevent this, the National Management Group (NMG) has approved the ToBRFV Eradication Response Plan. Under the Emergency Plant Pest Response Deed, the plan includes surveillance, testing and containment measures.

ToBRFV spreads easily via seeds, plant material, tools and human contact. GIA urges production nurseries to adopt biosecurity measures, including:

· enhanced hygiene: regularly clean tools and surfaces; consider footbaths and restricted access
· frequent monitoring: check for yellowing, leaf deformities or wrinkled fruit
· safe sourcing: use certified disease-free suppliers
· preventing cross-contamination: create designated zones and sanitise equipment between uses. For more information, visit pir.sa.gov.au/tobrfv
