Abstract

Rich, J. R., J. A. Brito, R. Kaur, and J. A. Ferrell. 2008. Weed species as hosts of Meloidogyne: A review. Nematropica 39:157-185. Over 226 weed species belonging to 43 botanical families have been studied for host suitability to different root-knot nematodes worldwide. Meloidogyne incognita was reported to reproduce on the largest number of weeds with over 138 weedy plant hosts throughout the world. Four other Meloidogyne spp., M. javanica, M. arenaria, M. hapla, and M. graminicola were found infecting 49, 48, 27, and 24 weed species, respectively, while M. mayaguensis, M. chitwoodi, and M. floridensis have been reported to reproduce on 24, 13 and 12 weed species, respectively. These data indicate that little is known about the exact weed host range of many species within the genus Meloidogyne. However, weed host status of Meloidogyne spp. reported herein indicates that weeds are a major reservoir of root-knot nematodes and should be considered as factors affecting the success of integrated nematode management programs.
