The Banana Is One Step Closer To Disappearing (nationalgeographic.com) 195

Posted by BeauHD from the fungus-among-us dept.
An anonymous reader quotes a report from National Geographic: A fungus that has wreaked havoc on banana plantations in the Eastern Hemisphere has, despite years of preventative efforts, arrived in the Americas. ICA, the Colombian agriculture and livestock authority, confirmed on Thursday that laboratory tests have positively identified the presence of so-called Panama disease Tropical Race 4 on banana farms in the Caribbean coastal region. The announcement was accompanied by a declaration of a national state of emergency. The discovery of the fungus represents a potential impending disaster for bananas as both a food source and an export commodity. Panama disease Tropical Race 4 -- or TR4 -- is an infection of the banana plant by a fungus of the genus Fusarium. Although bananas produced in infected soil are not unsafe for humans, infected plants eventually stop bearing fruit. First identified in Taiwanese soil samples in the early 1990s, the destructive fungus remained long confined to Southeast Asia and Australia, until its presence was confirmed in both the Middle East and Africa in 2013. Experts feared an eventual appearance in Latin America, the epicenter of the global banana export industry. No known fungicide or biocontrol measure has proven effective against TR4.

      You can still increase yield by planting more trees even if the plants are all getting sick. Then suddenly it all goes off a cliff.

      A similar la-la-la-we're-not-listening situation happened in the cod fisheries off new foundland in the 70s - idiot fisherman didn't listen to scientists (what do they know, they only study these things in depth, they don't haul nets like real men) telling them things were about to go south. And so the sea grunts carried on and wiped out the cod stocks. 40 years later there's still very little cod there.

The industry could probably come back again, as most popular fruits we have these days have all been genetically engineered over the centuries to look nothing like their wild ancestors. So breed new ones, start planting from seeds again, have multiple varieties, and avoid the agricultural idiocy that created this monoculture in the first place (and the politics that

          Then switch to a different variety. What's the problem?

          "The banana" is nowhere close to disappearing because there is not "the" (singular) cultivar of banana in existence. There's tons of them - most IMHO much better than the cavendish. The cavendish was just chosen because it was most similar to the gros michel, which was "the" previous banana.

          It's IMHO weird how it's seen as "normal" to have all sorts of different varieties of apples, grapes, citrus, etc etc in grocery stores, but most grocery stores only carry one variety of banana... and a rather mundane one at that.

          Cavendish bananas start getting too expensive? Grocery stores will start experimenting with other varieties and see which ones consumers like best. Higher prices on cavendish bananas vs. the newcomers will encourage consumers to abandon the cavendish. The best we can hope for is that it won't be just one banana cultivar on the shelves the next time.

            Clearly switching to more varieties is part of the solution, but the Cavendish cultivar dominates the banana industry for good reasons. It's tasty, easy to grow, and it ships well. It is the most profitable banana known.

              Actually, I think it has less to do with the taste, and more to do with your other points. Taste-wise the cavendish is one of the most bland and uninspiring banana varieties. Cavendish is visually appealing and handles rough shipping better than other varieties. There is less waste in getting the banana from farmer to final point of sale.

    The current Cavendish variety took over before a similar disease wiped out the previous one. The problem is that commercial bananas have no seeds, so the only way to get more banana plants is to clone them. All the plantations around the world are virtually genetically identical and are thus easy for diseases to wipe out. It's probably going to get solved via GMO, but still, expect a period where bananas dissapear from shops while all the plantations are replanted.
