The results of Biosecurity Queensland (BQ) surveillance done to date on the second infested property in the Tully Valley indicates that Panama Tropical Race 4 is contained within a relatively small area in one part of the property.
There are two distinct areas in close proximity where the disease has been confirmed. At the conclusion of sample diagnosis this farm had a total of 12 plants that were proven to be positive for TR4 (using the Vegetative Compatibility Group test), 11 in the first block of diseased plants and one plant in an adjacent block.
A further 16 samples were taken across the property and returned a negative diagnosis. Those negative sample results indicate a relatively early detection
BQ’s Panama TR4 Program is undertaking fortnightly surveys of all banana production areas on the property for the early detection of any further instances of the disease.
The farm owners have undertaken a number of steps to control and contain the risk of spread. This has included the destruction of all bananas in 16 hectares (40 ac) of land, which is over and above the requirements of the Biosecurity Manual and the Notice issued to the property owners. The owners have also fenced off the entire area, as well as the sites around where the diseased plants were found.
