A disease damaging banana crops in Southeast Asia has spread to the Middle East and Africa, posing risks to world supply and trade totalling $8.9 billion, according to the United Nations' Food & Agriculture Organisation.

The TR4 strain of Panama disease, a soil-born fungus that attacks plant roots, is deadly for the Cavendish banana that makes up about 95 per cent of supplies to importers, including North America and Europe, Fazil Dusunceli, an agriculture officer at the FAO, said by phone this week from Rome. While the disease hasn't reached top Latin America exporters such as Ecuador, Costa Rica or Colombia, TR4 was discovered in Jordan and Mozambique, indicating it moved beyond Asia, he said.

"The export market is dominated by the Cavendish, and it is unfortunately susceptible to this particular race of the disease," Dusunceli said.
