Abstract:
Root knot disease caused by root knot nematodes (RKN) or Meloidogyne spp. often cause a
serious problem for the celery farmers in vegetable centers in the sub-district of Landasan Ulin Utara,
Banjarbaru. However, until now there is no report regarding the species of Meloidogyne that causes
this disease in the Landasan Ulin Utara. This study aimed to identify the species of Meloidogyne on
celery through the morphological observation of the perineal pattern of female RKN. Celery plants
infected by Meloidogyne spp. were taken by a purposive method based on the typical root symptoms
from three locations in sub-district of Landasan Ulin Utara namely Kurnia, Sukamara, and Sukamaju
Ujung villages. Based on the characters of perineal pattern, three species of nematodes was identifed,
i.e. Meloidogyne arenaria, M. incognita, and M. javanica were found in those three sampling sites.
