Abstract:
Soil and root samples were collected to find out the horizontal and vertical distribution of citrus nematode, Tylenchulus semipenetrans in Lemon (Citrus Limon L.). Horizontal distribution of citrus nematode in Citrus limon L. exhibited an inverse relationship with distance where the average population of female / 5 g roots (113.10, 87.54 and 28.64); egg masses / 5 g roots (78.10, 56.38 and 16.74) declined as the distance from tree trunk was increased from 2 ft. to 4 ft. and 6 ft., respectively. While in case of eggs and larvae / egg mass, no significant change was seen. In vertical distribution of citrus nematode, nematode population declined sharply when increased the depth. Maximum density of citrus nematode was observed at a depth of 1 ft. followed by 1.5 ft. and 2 ft. Nematode population decreases in horizontal and vertical distribution may be due to lesser feeder roots in roots system.
