Tropical race 4 (TR4) has been reported in Laos and Vietnam, where symptoms typical of Fusarium wilt have been observed as early as 2014.
Laos and Vietnam are two of the countries in the region that have seen a surge in Cavendish plantations set up by Chinese investors to meet the demand for bananas in China, where TR4 is present in all banana-producing regions. The other countries are Myanmar, Cambodia and Thailand.
