This research focused on to test the reaction of cultivars and introductions of watermelon (Citrullus lanatus) and varieties of cotton (Gossypium hirsutum) to Rotylenchulus reniformis. Two experiments were carried out independently with treatments arranged in a completely randomized design. In the first one 4 cultivars ('Crimson Sweet', 'Charleston Gray', 'Sugar Baby' and 'Omaru Yamato') and 4 introductions ('MO-1 to MO-4') of watermelon were tested and in the second one 9 varieties of cotton ('BRS Ipê', 'BRS Rubi', 'BRS Safira', 'BRS 200 Marrom', 'IAC 23', 'Auburn 2', 'Deltapine 16', 'BRS 187-8H' and 'Deltapine 61'). Each treatment consisted of one genotype with 4 replicates witch consisted of one plant grown in a mixture of sterilized and naturally infested soil by 2.784 and 3.016 vermiform specimens in the first and second experiment, respectively. Cultivars and introductions of watermelon reacted as poor hosts while varieties of cotton reacted as good hosts of R. reniformis.
