Bananas are a huge part of our diets in Nigeria. Eaten raw (as bananas) or cooked, fried or roasted (as plantain) it contributes to our nutritional intake and is a significant economic crop to farmers'. It is important that the alarm bells start to ring here in Nigeria and appropriate enlightenment, quarantine, early warning systems and reaction protocols are set up before the disease gets here and wreck what is clearly a potentially devastating blow to farmers and the nation.
Here is a report from the BBC on the disease in some parts of Africa.
Battling to save the world's bananas
By Kim Gittleson
BBC business correspondent, Namialo, Mozambique
Visiting the Matanuska banana plantation is not easy these days. After a two-hour drive from the nearest city in northern Mozambique, visitors who make it to the farm are stopped at the entrance and asked to dip their feet in pools of disinfectant. Even the cars get a bath.
Once an apparent miracle - a massive banana plantation in the middle of a dry, flat part of a desperately poor country - its formerly lush greenery has now been devastated by a deadly fungus called Panama disease.
Five years ago, Tropical race 4 (TR4), as it's formally known, was spotted here for the first time in Africa after killing off millions of bananas in Asia from the 1980s onwards.
The failure to contain the disease set off alarm bells around the world.
Could the banana, the world's most exported fruit and the source of nutrients for millions of people, be at risk of extinction?
The BBC was the first to be given access to the farm since it was hit with the disease.
We travelled all the way to Matanuska not just to observe the devastation but because the story of the plantation is about more than just bananas.
It's emblematic of unintended consequences of global trade - and the way that solutions to those consequences might come from some very unlikely places.
After our disinfectant baths, we continued down a long, red dirt road to what remains of the farm. It's strikingly lush.
Trundling along on metal zip lines are hands as they're known - carrying hundreds of bananas to a processing facility, where they too get the bath treatment before being shipped off in Dole-branded containers to the Middle East.
Standing over this procession is Elie Matabuana, the farm's head of technical services.
He spends all his time looking at every banana grown here to see if they are exhibiting the yellowing leaves and tell-tale rotting smell that indicate a plant has been infected with Panama disease.
"When (I wake] up in the morning the first thing I have in my mind is; what can I do to stop the disease?" he says.
"It's a really big struggle but we are winning," he says, before amending his answer. "We are going to win."
Containment
But Elie and the Matanuska team are fighting an uphill battle. The disease has spread swiftly over the past five years.
"When I first came to Matanuska, it was just after we identified the pathogen and at that stage the farm was just beautiful," says Stellenbosch university professor Altus Viljoen, who was the first to confirm that the disease had in fact escaped Asia.
"I knew that that might change.
"But I never knew the extent of that change and how severe it would be."
Today, only 100 hectares are left of Matanuska's original banana plants.
Of the farm's 2,700 workers, nearly two-thirds have been laid off -- sending the surrounding economy into a spiral.
And containment, along with finding a resistant banana strain, has become a pressing priority.
It's estimated that more than half a million people are employed in the banana industry in Mozambique.
'Bad luck'
Neighbouring countries like Tanzania, just 600km north of Matanuska, also depend on banana cultivation for a significant portion of their economic activity.
And though the type of banana grown for sustenance in Uganda and Congo - where residents get something like 35% of their daily nutrients from bananas - is thought to be resistant, no one knows for sure.
"All African countries are worried about what's happening in Mozambique," says Antonia Vaz, the head of plant pathology at Mozambique's Ministry of Agriculture.
She says the Mozambican government has implemented control measures to ensure that the disease does not escape the northern part of the country.
She's also quick to note the disease isn't endemic to Mozambique. The government thinks it came from the boots of two workers from the Philippines.
"It was just very, very bad luck," she says.
Each year, more than $12bn worth of bananas, primarily of the Cavendish variety, are exported globally making it the world's favourite fruit both by value and by volume.
No cure
Usually if there are millions of dollars at stake, solutions aren't that hard to find.
But the problem in fighting Panama disease is the way that bananas are cultivated today.
The bananas that we eat are Cavendish bananas - often grown to the exclusion of all of the other thousands of types of bananas found in the world.
Growing only one variety of a plant is known as monoculture - and it's a practice that became increasingly common across the world in everything from forest plantations to fruit.
But monoculture crops are incredibly susceptible to disease.
What makes the story of the banana even more dire is that the Cavendish banana is what's known as a triploid - meaning it's sterile. New plants are produced asexually, meaning that they are genetically identical to the previous generation.
So hoping that evolution will eventually produce a resistant banana is futile - there is no natural selection to save the Cavendish.
