as the Gros Michel, but its bananas tasted good enough to keep consumers happy. Most importantly, TR-1 didn’t seem to affect it. In a few years, United Fruit had saved itself from bankruptcy by filling its plantations with thousands of the new plants, copying the same monoculture growing conditions Gros Michel had thrived in. While the operation was a huge success for the Latin American industry, the Cavendish banana itself is far from safe. In 2014, South East Asia, another major banana producer, exported four million tons of Cavendish bananas. But, in 2015, its exports had dropped by 46 per cent thanks to a combination of another strain of the fungus, TR-4, and bad weather. Growing practices in South East Asia haven’t helped matters. Growers can’t always afford the expensive lab-based methods to clone plants from shoots without spreading the disease. Also, they often aren’t strict enough about cleaning farm equipment and quarantining infected fields. As a result, the fungus has spread to Australia, the Middle East and Mozambique – and Latin America, heavily dependent on its monoculture Cavendish crops, could easily be next. Racing against the inevitable, scientists are working on solving the problem by genetically modifying the Cavendish with genes from TR-4-resistant banana species. Researchers at the Queensland University of Technology have successfully grown two
