| The root knot nematode (RKN), Meloidogyne incognita, is widespread worldwide and a major pathogen of several cultivated crops. The use of resistant genotypes is the most effective and environmentally sound way to manage RKN. In this study, we screened 16 selected sweet potato cultivars including Amanda, Bárbara, Beatriz, Beauregard, Brazlândia Branca, Brazlândia Rosada, Brazlândia Roxa, BRS Amélia, BRS Cuia, BRS Rubissol, Carolina Vitória, Duda, Júlia, Marcela, PA-26/2009, and Princesa obtained from Embrapa and Universidade Federal do Tocantins? germplasm bank. Studies were conducted under greenhouse and field conditions and the agronomic performance of the cultivars was evaluated in a nematode and soilborne insect-infested field. All 16 sweet potato... |

| Pratylenchus brachyurus has become increasingly common in soybean fields throughout Brazil where yield loss assessments have reported reduction up to 30%. Currently, no soybean cultivars resistant to P. brachyurus have been identified, and management strategies include crop rotation with non-host crops, fallow, and the application of nematicides. The goals of this study were to examine the population dynamics of P. brachyurus in soybean fields throughout Tocantins state and in areas planted with off-season crops following soybean harvest in a crop succession scheme. Pratylenchus brachyurus was present in ca. 82% of samples with densities in soybean fields ranging from 23 to 20,400 nematodes per 200 cm3 soil or 10 g root samples. In two sites, the mean... |
