A disease that causes banana plants to wilt and die has been found at a Queensland farm in a region that supplies more than 90 per cent of the fruit to Australia.

Farmers are being encouraged to maintain strict biosecurity* practices after a suspected case of the soil fungus Panama TR4 was detected at the far north Queensland farm.

The disease is the biggest biosecurity threat to Australia’s $580 million banana industry and eradication of the disease is not feasible*.

The farm is in the Tully Valley — near the town of Tully — south of Cairns, close to three other properties infested* with the disease first found in Queensland in 2015.

There has been a positive first test for the disease but it could take up to four weeks for a final result, Biosecurity Queensland’s Rhiannon Evans said.

The fungus attacks the banana’s vascular* system, causing wilting and death of the infected plant.

media_cameraPanama disease is a fungus that attacks the roots of the plant and causes it to wilt. It is resistant to fungicide chemicals.

It is estimated that 80 per cent of global production is under threat from the fungus.

The Queensland government has so far spent $42 million to manage the disease in the state’s far north.

Australian Banana Growers’ Council Chair Stephen Lowe said the industry knew the disease would eventually spread but it’s still bad news.

“This is definitely news that no one in our industry wanted to hear,” Mr Lowe said.

“First and foremost, our thoughts are with the grower affected.

“This is no doubt going to be a challenging time for them and their family, and we will look to help them through this in any way we can.”

Queensland accounts for more than 90 per cent of Australia’s banana production with most of the farms based in the state’s far north.

People and machinery movement are the biggest threat of disease spread but heavy rainfall and flooding can also see it move.

The disease is not harmful to humans and does not affect the fruit.

In early 2011 Cyclone Yasi hit the same part of Queensland and wiped out banana crops, leading to banana shortages.
