Root-knot Nematodes in Thailand: A Current Overview
Root-knot nematodes (Meloidogyne spp.) are currently viewed as the most damaging plant-parasitic nematodes occuring in Thailand. A range of crops, such as vegetables, ornamentals, fruit trees, and field
crops have been reported as hosts for these pests. To date, ninespecies of root-knot nematodes have been identified in Thailand: M.
arenaria was reported from onion in the Central region of Thailand; M.
exigua and M. graminicola from lowland rice paddy fields in the Central and the Northeastern regions of Thailand, respectively; M. hapla was
encountered in more temperate conditions in the highlands of Northern Thailand on ornamentals and herbs; M. incognita, the most prominent and widespread species, are frequently recovered and associated with damage to over 60 plant species throughout the country, while M.
javanica has been associated with tuberose and gerbera in a localised
area of central Thailand. Other species identified include M.
microcephala from tobacco in Northern Thailand, a single record of M.
nasi from sorghum in the Northeastern region, and a recent identification of M. enterolobii causing severe damage to guava near
Bangkok. However, some identifications are based on perineal patterns alone, from before the advent of molecular techniques, while M.
enterolobii was identified using a combination of esterase enzyme patterns, and DNA analysis. Although potato, chilli and guava are currently identified as three key crops that are heavily affected by root
knot nematodes, it is suspected that much greater damage is occurring across crops. A recent report of root knot nematode damage on cassava is currently being assessed, for example. In Thailand, research areas requiring an emphasis and strong engagement include techniques for more accurate diagnosis towards delivery of appropriate management
options. Improving identification, and knowledge on nematode-host or nematode- pathogen interactions, is desired towards improved control.
