Banana Disease Reaches Jordan

One of the most damaging diseases of banana plants has spread beyond Southeast Asia. Fusarium wilt, or "Panama disease," is caused by a soil fungus that wiped out banana plantations by the mid-20th century, until they were replanted with a resistant crop. But 20 years ago, a devastating new variant of the fungus, tropical race 4 (TR4), emerged in Taiwan. It has spread to several countries including China, the Philippines, and Australia.

Now, scientists have confirmed that TR4 is in Jordan. Although only 1500 hectares there are planted with bananas, 80% of the area is infected, underscoring concerns about how easily the pathogen can spread. Researchers from Wageningen University in the Netherlands and other institutions analyzed DNA from fungus samples collected by the Jordanian Ministry of Agriculture and confirmed that they were TR4, the scientists reported online in Plant Disease.  

Banana Disease Reaches Jordan
The researchers called the jump from Asia a "dangerous expansion" of the range and fear that the disease will reach Africa and Latin America, which not only export many bananas but also rely on them for food security.
