Banana Industry on Alert After Disease Arrives in Colombia Associated Press LA GUAJIRA, COLOMBIA - It might not be obvious at the supermarket, but thebananaindustry is fighting to protect the most popular variety of the fruit from a destructive fungus. A disease that ravagesbananacrops has made its long-dreaded arrival in Latin America, the biggest exporter of the crop. That's reigniting worries about the global market's dependence on a single type ofbanana, the Cavendish, which is known for its durability in shipping. For years, scientists have said bigbananacompanies like Chiquita and Dole would eventually need to find newbananavarieties as the disease spread in countries in Asia and elsewhere. Then this month, the fungus was confirmed inColombia, one of the top exporters in Latin America, prompting officials in the country to declare a state of emergency. Bananaindustry watchers say it's more proof the Cavendish's days are numbered, but that there's still plenty of time to find alternatives. "I don't think it's going to impact the availability of the Cavenidsh in supermarkets anytime soon,'' said Randy Ploetz, a retired scientist from the University of Florida who studied tropical plant diseases. While all sorts ofbananasare grown around the world for domestic consumption, the ones shipped to places including the United States and the European Union are mostly Cavendishes. It may seem odd that the worldbananamarket would hitch its fortunes to a single variety, but mass producing just one kind is a way to keep costs down, which also helps makebananasso widely available. Bananasare also hard to breed, and finding varieties suited to global commerce isn't easy. In addition to being productive, Cavendish plants yieldbananasthat can survive the trip from warm climates to far-flung supermarkets, without ripening too quickly. Still, history has shown the risks of relying on a singlebanana variety. Not that long ago, the world market was ruled by anotherbanana, the Gros Michel, aka the Big Mike. Experts say it was even easier to ship than the Cavendish, and sweeter (though others contend it tasted similar). Either way, the Gros Michel was ravaged by the 1950s by an earlier strain of the disease now stalking the Cavendish. This time, there's no obvious backupbananawaiting in the wings to take over. .
