First report of Meloidogyne enterolobii in Vietnam
In Southern Vietnam, citrus trees are often planted together with guava (Psidium guajava) for the management of huanglongbing (citrus disease associated with ‘Candidatus Liberibacter asiaticus’). Some guava seedlings showed decline symptoms including brown discouloration of the leaves, growth inhibition, leaf drop and finally died. Affected seedlings also presented numerous galls on the roots, suggesting the presence of root-knot nematodes. Morphological and molecular studies confirmed the presence of Meloidogyne enterolobii (EPPO Alert List) on diseased guava seedlings. This is the first report of this nematode in Vietnam.
The situation of Meloidogyne enterolobii in Vietnam can be described as follows: Present, first reported in 2009 on Psidium guajava in the southern part of the country.
