Bye Bye Bananas — the Return of Panama Disease 519

Ant sends in a disturbing report in The Scientist on an imminent threat to worldwide banana production. "The banana we eat today is not the one your grandparents ate. That one — known as the Gros Michel — was, by all accounts, bigger, tastier, and hardier than the variety we know and love, which is called the Cavendish. The unavailability of the Gros Michel is easily explained: it is virtually extinct. Introduced to our hemisphere in the late 19th century, the Gros Michel was almost immediately hit by a blight that wiped it out by 1960. The Cavendish was adopted at the last minute by the big banana companies — Chiquita and Dole — because it was resistant to that blight, a fungus known as Panama disease... [Now] Panama disease — or Fusarium wilt of banana — is back, and the Cavendish does not appear to be safe from this new strain, which appeared two decades ago in Malaysia, spread slowly at first, but is now moving at a geometrically quicker pace. There is no cure, and nearly every banana scientist says that though Panama disease has yet to hit the banana crops of Latin America, which feed our hemisphere, the question is not if this will happen, but when. Even worse, the malady has the potential to spread to dozens of other banana varieties, including African bananas, the primary source of nutrition for millions..."

  • but it is also solved by genetic variation. the story is a little hysterical, as african varieties are also genetically different enough to resist the new cavendish-hungry fungus. not that the african varieties can't be attacked, but the emphasis is on african VARIETIES: more genetic variation means more resistance to the weakness of monoculture

      The problem is that all banana plants around today are sterile. The only way to cultivate new plants is by cuttings (taking a small section of an existing plant and growing it into a big plant). Consequently there is no way to introduce new variations. If all the varieties around today become susceptible to disease then that's it, they're gone. For those of us in the west that's just one less choice in the supermarket, but there are vast swathes of the world where the banana is the staple carbohydrate source for millions of people. It'd be like the west no longer having anything to make flour for bread, and having no alternative. Anyone who thinks this isn't a huge problem is wrong.

        They are not all quite sterile... you do get a seed for every few hundred pounds of bananas.

        That said, you are essentially right. All cavendish bananas are clones, this makes them very vulnerable to disease.

      Actually, New Scientist did a story about this, maybe five years ago, which was worried about the bananas' genetic variation, but didn't have any specific threat attached. They pointed out that although the current banana plants is pretty hardy, they're cultivated by cloning, so there's very little capacity for adaptation there. I forget the details of the story, but it was something like "there may not be any bananas as we know them in 25 years". Now the threat actually exists...

        Yes, monoculture is a HUGE problem.

        At the moment I'm working in the bio/ag-tech industry and can see the same thing coming down the road in the wheat/corn/soybeans/milo industry, where big industry players have foolishly limited the gene pool in the name of profit.

        The worst part about it is the fact that many of the people driving monoculture are trained scientists who, for some reason, are oblivious to its negative ramifications.

          It's not that scientists are oblivious to negative ramifications -- it's economics, specifically tragedy of the commons.

          If everyone else is cloning Tasty Profitable Banana, and you don't, you go out of business because either your bananas aren't Tasty or your bananas aren't Profitable. Therefore there's a penalty for maintaining variation, and the only potential benefit -- not having your whole crop wiped out by a blight -- isn't something you can bet on. Most likely, economic forces will drive you out of business long before your more varied gene pool can have any beneficial effect.

          There's a benefit to society (and the entire banana-growing industry) if there is a diverse gene pool, but no individual business has an incentive to maintain such a gene pool.

        For the most part, they (we?) won't. Most varieties of Banana's are rather small and nasty. They're not the kind of thing your average westerner is likely to enjoy.

        On the other hand, assuming they can find a variety of Banana which is easy to cultivate, resistant to this disease, AND tasty, then it'll be a huge boon to their economy. It could do more good for Africa than all the foreign aid of the last three decades combined.

          Or, of course, the 3 or 4 big banana companies of the earth (which are all 'western'), will jump into the void and start exploiting African banana farmers, let them work in dangerous conditions, using chemicals, and not nearly paying them enough to make a proper living.

        Go to your local African food store and ask for Plaintain. Eat it (note that Plaintains are usually cooked first). Now you see why this is not going to be a problem.

        Being married to an African woman (Nigerian to be precise), I've had the misfortune of tasting Plaintain, and while I don't mind most of her food (it's usually either too bland and uniformely textured or too spicy for me, but generally edible), with Plaintain I see no redeemable qualities.

        It's a very acquired taste, as a lot of African staple food, and it's certainly no replacement for the types of Banana exported to the west.

          Then you've only had plantains one of the two ways in which they're eaten. I agree that green plantains aren't my cup of tea. In my opinion they're like overly firm and starchy potatoes with a hint of banana flavouring to them. After a week of traveling Panama, I never wanted to see them again.

          However, if you let plantains ripen until they're black (at which point, they're still perfectly edible, unlike bananas) and then peel them, cut them into long slices, and cook them in butter, they're incredibly sweet and delicate.

          More in line with the original post, there are several varieties of bananas that I find much more delicious than the Cavendish variety. I've had the pleasure of eating several other varieties while abroad that I really enjoyed; for example, apple bananas have got a firmer, more flavourful meat to them, and I strongly prefer them to Cavendish. Cavendish bananas, although I love them, can be a bit dull tasting and mushy.

  • According to Banana.com [banana.com] there are over 300 different species of bananas, not all edible. I'm fairly certain that not all the edible species will be susceptibe to the blight. This might actually be a good thing in the long run as different species have different flavors and textures. They may even be better for us from a nutritional perspective than the Cavendish. The growers will need to adapt if the blight can't be stopped or contained.

    Single, cloned fruit, unable to reproduce except by human intervention, with identical genetic structure in virtually all examples, cloned and distributed worldwide for decades is susceptible to the same attacking fungus that attacked the previous single, cloned fruit with identical genetic structure, but which has mutated slightly (my conjecture) in order to attack it's replacement.

    And all because people don't like seeds in their fruit? (I would guess this isn't true, most probably people wouldn't really care much anyway, given that the fruit has an inedible skin too and a lot of popular fruits have seeds).

    It's hardly surprising, it's only "catastrophic" because we've deliberately propogated a single, genetically-identical (and I would hazard "faulty", due to it's inability to reproduce) plant over and over and over again.

      Actually, that's a slightly hedged 'yes'.
      Grampa's banana had a thicker, more durable skin, in addition to being larger than the bananas we youngun's know so well.
      The other reason it's so popular as comic relief is because it actually was a real hazard back around 1915-ish. As a 'portable' fruit, they were handy to carry anywhere, and without streetcorner trash cans, the peels got tossed on the sidewalk as often as not. And considering bananas are (and were) the most popular fruit in the US (almost twice as popular as the good ol' apple), it really was a normal hazard. The Boy Scout handbook of 1914 actually listed removing a banana peel from the sidewalk as a 'good deed', it was that common an occurence.

      As a side effect though, it *did* start many cities putting trash cans on busy streets, and enacting littering laws.

        I had to sit down because I was laughing so hard. I never expected to ever slip on a banana peel in my life time. I laughed ever harder when I remembered I saw the banana in the morning walking to campus and thought 'Silly banana peels. You just aren't so effective of a threat anymore.'

    I know it's against the rules but if you RTFA the interesting part isn't about the blight spreading through the bananas. As others have posted this is not something that sprang up over night, it's been coming for quite a while now.

    The truly interesting part is that the banana companies in S. America still don't see this as a problem. TFA says that in their anual summaries they don't even mention this disease much less list it as a threat. I think the issue is much more about these companies' failure to act before it's too late than that nature is running its course.

    Having traveled in some tropical countries, one of the things I most remember about their fruits are the sheer NUMBER of different banana varieties. No monoculture. Your average roadside stand would have half a dozen varieties, and the one a mile down the road would have a few more. Tomorrow the mix would be different. And most of them would taste a lot better than the crap that's so widely available elsewhere!

      Unfortunately none of those dozens of varieties have the attributes that make the Cavendish banana by far the most successful and important fruit crop in the world:

      1. Long shelf life
      2. Very uniform and predictable ripening times

      That is why you can get bananas cheaply, even though they might be grown thousands of miles from where they are eventually sold.

      Most, if not all the other varieties are only viable crops when they are sold very close to where they were grown.

      I've done the same and I'll wholeheartedly agree. The only saving grace, at least for me, is that one can typically find plantain available in most supermarkets. Let them ripen (until black) in a paper bag, fry them, and add to a plate of black beans and rice with some Cuban-style coffee on the side, and Bob's (or maybe Fidel) yer uncle.

      As a side note, I do think the tendency for westerners to buy bananas out of habit is a disease. People have written essays and even books on why fruits and vetegables should be bought local, and then, only when in season. The idea of eating summer fruits when there's snow on the ground might be novel, but hardly appropriate, or interesting. Conversely, seeing a California supermarket in the middle of summer selling bananas (and their customers lining up to buy them) when just about every type of fruit is ripe for the picking is, well, no less than absurd.

Looks like it's slow going, but genetic mutation is pretty much the only way to engineer in resistance to new disease, and that will require seeds, not cuttings.
