Abstract

No root galling or egg mass formation was noted on betel palm (Areca catechu) 3 or 9 months after inoculation with Meloidogyne arenaria, M. hapla, M. incognita races 1 and 3, or M. javanica. Compared with uninoculated controls, a reduction (P = 0.05) in fresh root weight was noted after 3 months with M, incognita race 1 but not with other species or races, No differences (P = 0.05) in root weight between controls and inoculated plants were observed at 9 months, nor were any differences found in top weight at 3 or 9 months. Key words: Areca catechu, betel palm, host range, Meloidogyne spp., palm, pathogenicity, root-knot nematode.
