Biosecurity measures under the National Tomato Brown Rugose Fruit Virus (ToBRFV) Response Plan are ongoing at an infected property in northern Victoria. The property is actively replanting glasshouses and testing incoming seedlings for the virus. Recently, a new positive detection of ToBRFV was identified among the seedlings.
The source of this new infection is under investigation. Given that the seedlings had only been on the property for a few days, it is considered unlikely that the infection originated on-site. The seedlings were sourced from a commercial nursery in New South Wales, where no previous detections of ToBRFV have been reported.
Victoria's Chief Plant Health Officer, Dr. Stephen Dibley, confirmed that quarantine measures remain in place at the affected property. Agriculture Victoria is collaborating closely with the business to prevent further spread of the virus. "We understand this is a challenging situation for the affected business. Our focus remains on supporting business continuity and safeguarding the welfare of all involved," Dr. Dibley stated.
Dr. Dibley further emphasized that there is no evidence of ToBRFV in any other locations in Victoria.
ToBRFV is a highly contagious plant virus that primarily affects tomatoes, capsicums, and chillies. It spreads easily through contaminated tools, hands, clothing, and direct plant-to-plant contact, including grafting and cuttings. The virus can also be transmitted through seeds and irrigation water.
The virus can persist in seeds, plant waste, and contaminated soil for months. Once a crop is infected, eradication requires the destruction of all affected plants and contaminated materials. However, ToBRFV poses no risk to food safety or human health from consuming infected tomatoes.
ToBRFV was first detected in South Australia (SA) in August 2024 and is currently known to be present on four properties in SA. It was confirmed in Victoria in January 2025.
Victorian tomato and capsicum growers, as well as home gardeners, are encouraged to regularly monitor their crops and contact Agriculture Victoria if they suspect any signs of ToBRFV.
