Banana RIP?

So warns this article from The Scientist, a story that recounts the last 100 years of commercial marketing of the banana. From the story by Dan Koeppel:

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. For the past fifty years, all has been quiet in the banana world. Until 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 of people.

Crop disease is only half the problem. The other part is denial. One of the most recent places Panama disease struck was Australia. Three years ago, when I was researching my book on bananas, growers down under were bragging that they'd found a way to control the disease, which first appeared in 1997 near the Northern Territory town of Darwin. "We have developed a rapid and accurate DNA-based diagnostic test...used in the detection and management of outbreaks," asserted a brochure issued by the country's Cooperative Research Centre for Plant Protection.



TK: Koeppel suggests that banana companies are unwisely downplaying the risk of Panama disease in Central and South America and notes that the next banana variety with wilt resistance will come from a biotech lab.
