The problems caused by nematodes and by the Panama disease on banana plantations are responsible for production losses and limiting to its cultivation. In the state of Goiás there is few information about the nematode genus that affect this crop, and its relationship with the incidence of the fungus Fusarium oxysporum f. sp. cubense (Foc). This research aimed to survey the occurrence of plant parasitic nematodes, the incidence of Foc and soil attributes, and determine if there is a correlation among these factors. In January 2015, twelve banana producing regions in the state of Goiás were sampled: Anápolis, Caiapônia, Goiatuba, Itaguaru, Itumbiara (two areas), Jataí, Morrinhos, Ouro Verde, Palestina, Taquaral and Uruana. All sampled areas, except Morrinhos, revealed contamination with Foc, and all had different genus of nematodes. Meloidogyne sp., Helicotylenchus sp. and Rotylenchus sp. were the main genus of plant parasitic nematodes present in the banana plantations, with Meloidogyne sp. and Rotylenchus sp. the most dominant and abundant genus. We found that Pratylenchus sp. increases the population levels of F. oxysporum and that Helicotylenchus sp. has been affected by the concentration of P, Ca, Mn and the soil pH.
