It begins in the soil and travels to the root system, then enters the corm and passes into the pseudostem. Banana wilt – Another fungus, Fusarium oxysporum, causes Panama disease or Banana Wilt (Fusarium wilt). Erica Chayes Wida is a New York City-area based journalist and food writer obsessed with culture, poetry and travel. Genetic engineering can lead to the development of new varieties at much faster rates than traditional breeding methods, but it can also turn consumers off. It’s a very good lesson for us.”. Back then, the most popular type of banana was the Gros Michel, so to combat the risk of infection to that type of banana, large growers like Chiquita and Dole switched to the Cavendish which, at the time, was immune to that strain of the disease. Microsoft implemented one of the first large-scale commercial developments of artificial diversity in their Windows OS system, by randomizing the internal locations where important pieces of system data were stored. Desperate for a solution, the world’s banana farmers turned to the Cavendish. Much of the world's bananas are of the Cavendish variety, which is endangered by a strain of Panama disease. Save on the cover price & free e-Gift card for Giftees! Today, however, no type of banana has appeared resistant to the super-deadly TR4 strain. As the Gros Michel was ravaged by disease, the Cavendish banana took over the world’s markets and kitchens. If TR4 is not contained, it has the capability to wipe out most large banana farms which mostly grow one type of banana: the Cavendish. Fernando García-Bastidas, a Colombian phytopathologist, told National Geographic that for now, both the ICA and local Colombian farms are doing a good job at containing the infected crops. Frank Bienewald—LightRocket via Getty Images, A Colombian worker carries crude bananas to a transport car at a banana plantation. The banana has been the subject of Andy Warhol’s cover art for the Velvet Underground’s debut album, can arguably be the most devastating item in the Mario Kart video game franchise and is one of the world’s most consumed fruits. Panama disease, also called banana wilt, a devastating disease of bananas caused by the soil-inhabiting fungus species Fusarium oxysporum forma specialis cubense.A form of fusarium wilt, Panama disease is widespread throughout the tropics and can be found wherever susceptible banana cultivars are grown. The situation led Colombia—where the economy relies heavily on the crop, as it does in several other countries including Ecuador, Costa Rica and Guatemala—to declare a national state of emergency in August. An earlier strain of Panama disease called Race 1 first devastated banana farms throughout South and Central America in the 1950s. The Gros Michel was the only type of banana eaten in the United States from the late 19th century until after World War II. There’s a name for this situation: monoculture, the practice of fostering just one variety of something. Because banana farmers are overwhelmingly growing the same exact crop—the Cavendish—they were all vulnerable to the same diseases. The Cavendish banana has proved popular among producers and exporters for its high yields and durability over long transportation. The world’s bananas are under attack . Even if the world’s relationship to bananas may never be the same, the lessons of the fruit can still save us from damage that could hit far beyond the produce aisle. According to the BBC, the Cavendish accounts for nearly half of bananas grown worldwide and nearly all of the bananas imported to the U.S., Europe and the U.K. Monoculture has its benefits. The switched worked. It's a sweet, somewhat bland banana closely associated with large-scale operations like Dole and Chiquita. The Cavendish hasn’t always been popular. In fact, the entire banana supply chain is … On average, says Chris Barrett, a professor of agriculture at Cornell University, citing that U.N. data, every person on earth chows down on 130 bananas a year, at a rate of nearly three a week. “To make a system artificially diverse, you just rearrange its guts in ways where the differences do not affect functionality in a material way,” Schneider says. This disease is lethal. Use of this site constitutes acceptance of our, What We Can Learn From the Near-Death of the Banana. But that wasn’t always the case. The disease was serious and diagnosed in Panama banana plantations of Central America. Cavendish banana varieties are reproduced asexually. The Cavendish hasn’t always been popular. While bananas grown in infected soil are not unsafe for humans to eat, banana plants that have been infected will stop bearing fruit, so as fewer plants thrive, it will become more costly and more difficult for the U.S. to import bananas. Almost a decade ago, Dan Koeppel, author of Banana: The Fate of the Fruit That Changed the World, warned in an NPR interview that Panama Disease would return to the world’s largest banana exporters, and this time with a strain that would hit the Cavendish hard. (Photo by Jan Sochor/Latincontent/Getty Images), Who Should Be TIME’s Person of the Year for 2020? For example, the 1988 Morris Worm infected an estimated 10% of all computers connected to the Internet within just 24 hours, and, more recently, the 2016 Mirai Botnet, which allowed an outside party to remotely control a network of internet-connected devices, brought down Twitter, Netflix, CNN and more. However, developing a plant that can endure the climate and terrain of South America, as well as mimic the appearance of a banana most people love, may take many, many years. Since Central and South America are home to the world's biggest markets for growing and exporting bananas, the impact of a widespread infection would be detrimental to the fruit's global supply. Contrary to this notion, in mid-2008, reports from Sumatra and Malaysia suggested that Panama disease had started attacking Cavendish cultivars. After years of attempting to keep it out of the Americas, in mid-2019, Panama disease Tropical Race 4 (TR4), was discovered on banana … Sign up to receive the top stories you need to know now on politics, health and more, © 2020 TIME USA, LLC. Leaves begin to yellow, starting with the oldest leaves and moving in towards the center of the banana. Banana wilt – Another fungus, Fusarium oxysporum, causes Panama disease or Banana Wilt (Fusarium wilt). Schneider points out that software monocultures are common because, without them, using your computer would be a lot harder. According to Gert Kema, a professor of tropical phytopathology at Wageningen University whose lab leads research about the Panama disease, this is not the first time banana growers have been faced with a dire situation. Vote Now, U.S. May See 'Surge Upon Surge' of COVID-19, You can unsubscribe at any time. Leaves begin to yellow, starting with the oldest leaves and moving in towards the center of the banana. Existing disease-resistant varieties haven’t made inroads on the international market, but The Honduras Foundation for Agricultural Research (FHIA) has spent more than three years working on developing a disease-resistant variety that is as close as possible to the Cavendish, so that the world’s banana infrastructure doesn’t have to be reshaped from scratch. Will it simply disappear from our diets, album covers and video games? But no, they’re not about to go extinct. If someone or something figures out how to affect just one, the entire system is put at risk. The switched worked. But the bigger problem is how hard it is to stop. “Science,” he says, “will find a way.” Meanwhile, tech researchers are watching—hoping they can once again learn a lesson from biology, learning how to prevent a crisis before everything goes bananas. A deadly plant fungus has begun to infect banana crops in a region experts have long feared would be especially susceptible to disease. Tropical Race 4 was found in Darwin in … Plants of one variety are genetic clones of the parent plant. Sure enough, the confirmation of the presence of Tropical Race 4 (TR4), another strain of Panama disease, on banana farms in Colombia, prompted this summer’s declaration of emergency there. However, it has been the answer to similar problems in the past—for example, when the papaya ringspot virus threatened the papaya supply in the 1990s, “the major supply shock was averted through the development of a transgenic ringspot virus-resistant papaya,” explains Cornell’s Barrett. However, it too is now under threat from both Black Sigatoka and a new strain of Panama disease. The Cavendish banana may have had a remarkable journey from colonial curiosity to … Over several decades, the fungus spread from Panama to neighboring countries, moving north through Costa Rica to Guatemala and south into Colombia and Ecuador. The fruit of an infected banana plant is not affected by the fungus, and is still safe for human consumption. Default configuration settings, for example, are the norm to help users who may not be experts in the technology they’re using. Cyber Monday is just hours away! “With people, of course, populations are stronger and more disease-resistant if there’s more genetic diversity. Defaults like that can protect people from some problems, but also lead to others, as all the systems using the same default are vulnerable to the same problems. The UK-based biotech company Tropic Biosciences has received $10 million in funding to use gene-editing technology to research solutions to widespread issues with tropical crops, focusing specially on disease resistance in bananas. Write to Anna Purna Kambhampaty at Anna.kambhampaty@time.com. A potential savior, say researchers, would be to create a different type of banana through selective breeding that is a different species than the Cavendish. On the other hand, as banana farmers learned, in a monoculture, all instances are prone to the same set of attacks.
