Host status of herbaceous perennials to Meloidogyne incognita and M. arenaria
1998
Walker, J.T. | Melin, J.B.
Twenty-two different herbaceous perennials were studied for their reaction to separate inoculations of Meloidogyne arenaria and M. incognita under greenhouse conditions. Perennial taxa that did not develop root-galls following inoculation, and therefore are considered as nonhosts of both nematode species, included species and cultivars of Aethionema, Fragaria, Phlox, and Polygonum, and Patrinia developed only a few galls. Root galls developed on species and cultivars of Achillea, Geranium, Heuchera, Heucherella, Linaria, Nepeta, Nierembergia, Penstemon, and Salvia. There was no difference in the number of root galls caused by M. arenaria or M. incognita on most plants except for Penstemon cultivars. Plant heights and dry weights varied between species and nematode density.
