If you think you have seen Panama TR4, you must report it to Biosecurity Queensland on 13 25 23 within 24 hours. Panama TR4 is category 1 restricted matter under the Biosecurity Act 2014. Suspect plants must be reported to Biosecurity Queensland within 24 hours on 13 25 23. For a free copy of the disease identification guide, contact the ABGC on who access paddocks on a regular basis are best placed to check plants, which can be done at any time of year and crop stage.Īll individuals and organisations have a responsibility to protect the banana industry from Panama TR4 and limit the spread of this disease. Surveillance for Panama TR4 outlines the best method to checking plants for signs of the disease. Growers should regularly check their plants for signs of Panama TR4. All information about Panama TR4 management through the TR4 Control Program can be found at. ABGC conducts routine surveillance in accordance with its surveillance strategy. The peak industry representative body, the Australian Banana Growers' Council (ABGC) has taken the lead to manage Panama TR4. The last round of Queensland Government surveillance for Panama TR4 took place during the 2022–2023 financial year. This means the fungus may have already spread to other banana growing areas by the time an infection is detected.īiosecurity Queensland's Panama TR4 Program has undertaken surveillance since the disease was first detected in the Tully Valley, Far North Queensland in 2015. The time frame between initial infection and disease development may range from a few months to 1 or more years, depending on environmental conditions and the plants' age. It takes only 1 microscopic spore to infect a new banana plant. As this happens, the fungus produces more spores that can spread the disease. The plant literally starves and eventually wilts and dies. The fungus blocks the plant’s vascular system preventing movement of water and nutrients. The fungal hyphae grow through the corm into the vascular system within the pseudostem. When the spores are in very close proximity with a banana plant, they germinate and produce threadlike hyphae that enter the roots through natural openings and wounds, such as those caused by nematodes and banana weevil.
