| This study aimed to assess the levels of resistance of 10 advanced sweetpotato cultivars to this nematode species. Two experiments were carried out in 2018/2019 and 2021/2022 seasons, under greenhouse conditions in Brasília-DF, Brazil. A completely randomized block design with six replicates of one plant/plot/treatment was used. |

| Thus, in order to identify the best population level for inoculum of the rootknot nematode (Meloidogyne incognita) for maximum expression of symptoms of this nematode attack on carrots, an experiment was carried out to evaluate the carrot cultivar Brasília (CBR) and the population Pop-750 (CRO). The experiment was carried out in a greenhouse at Embrapa Vegetable, Brasília-DF, in 5 L pots, with six replications, in a 4x2 factorial scheme in a completely randomized design, in the dosages of 0, 1, 5 and 10 thousand eggs and occasional juveniles of 2nd stage (E+J2R). |

| Grafting has been increasingly used to overcome soilborne pathogens. The commercial rootstock hybrids AF-8253 (Sakata) and Fortaleza (Takii), as well as Embrapa?s new hybrid, BRS Acará, were evaluated as rootstocks for the bell pepper hybrids Margarita (Syngenta) and Pampa (Clause) as scions, under natural infestation of Ralstonia pseudosolanacearum, as well as upon artificial inoculation with a) ten Ralstonia isolates, b) one Phytophthora capsici isolate, c) Meloidogyne incognita race 1, and d) Meloidogyne enterolobii (only rootstocks for c and d). Grafted bell peppers consistently showcased a higher productivity than did non-grafted ones under natural R. pseudosolanacearum infestation, and the rootstock genotype affected fruit size distribution.... |

| Meloidogyne izalcoensis Carneiro et al., 2005 foi recentemente detectada no Brasil, parasitando cafeeiros na região do Triângulo Mineiro, MG. Dessa maneira, a fim de determinar a distribuição desse nematoide nessa região foi realizado um levantamento de Meloidogyne spp. em cafezais nos municípios de Araguari e Indianópolis. No início do levantamento, o perfil de esterases foi usado, mas com essa metodologia não foi possível detectar M. exigua. Assim, optou-se pelos marcadores SCAR-café que detectaram todas as espécies em multiplex. |

| The objective of this work was to prospect sources of resistance to the root-knot nematode Meloidogyne enterolobii in wild Solanum species and hybrids to be used as potential rootstocks for cultivated Solanaceae. Twenty-three accessions of seven Solanum species, as well as 35 interspecific hybrids of two crosses, were characterized for their resistance to M. enterolobii. The experiments were conducted in a greenhouse in Brasília-DF, Brazil, in a completely randomized block design with four replications of one plant per pot. Plants were inoculated with egg masses and evaluated for the nematological variables egg mass index, galls index, number of eggs per root gram and reproduction factor. Solanum torvum, S. paludosum, and S. paniculatum presented high... |
