Da Xanh grapefruit is a fruit tree with many nutrients and high economic value. However, nematode attack is one of the factors that limit productivity. Based on the approach of surveying gardens with symptoms of yellow leaves and root rot, collect and analyze samples. Results of surveying the composition of plant parasitic nematodes in Tien Giang province discovered 11 genera belonging to 8 families of plant parasitic nematodes present in the soil and root zone of Da Xanh grapefruit trees. Thus, 12 nematode species have been identified including: Aphelenchus avenae, C. onoensis, Helicotylenchus crenacauda, H. digonicus, P. coffeae, Rotylenchulus reniformis, Rotylenchus dalhousiensis, Tylenchorhynchus leviterminalis, Tylenchulus semipenetrans, Xiphinema insigne, X. longicaudatum. The species T. semipenetrans appeared at 80% and 76.67% in soil and root samples, which is an important species that needs to be controlled; P. coffeae and R. reniformis are dominant in roots and should be of concern as populations increase. Besides, it also shows that in garden samples with yellow leaf and root rot symptoms, the population of T. semipenetrans nematodes is very high compared to previous studies.
