Meloidogyne nataliei is a root parasite of Vitis labruscana cv. Concor
d. Evaluation of 20, 7, and 9 plant species as potential hosts for thi
s nematode under greenhouse, field, and growth chamber conditions, res
pectively, indicated that M. nataliei has a narrow host range. Nematod
e development and reproduction were not observed on 30 of the species.
Five new hosts of M. nataliei were identified: three Vitis rootstocks
(5BB, St. George, and Gloire), Parthenocissus quinquefolia, and P. tr
icuspidata.
