• Abstract:

  In order to study the occurrence of phytonematodes in areas of cultivation with guava in the southern region of Goiás, a phytonematological survey was carried out in 30 properties, in a total area of 80 hectares, between January and March 2016. Soil samples and roots were collected in 14 municipalities: Água Limpa, Bom Jesus de Goiás, Buriti Alegre, Caldas Novas, Corumbaíba, Edealina, Goiatuba, Hidrolândia, Itumbiara, Joviânia, Morrinhos, Piracanjuba, Pontalina and Rio Quente. The main genera/species of phytonematodes found were: Helicotylenchus; Xiphinema; Rotylenchus; Criconemoides e Tylenchus; Ditylenchus; Scutellonema and Tubixaba; and Meloidogyne javanica and Hemicycliophora. It is worth mentioning the wide dissemination of the first two genres, in addition to the first report of Tubixaba spp. associated with guava in the southern region of Goiás. The present study contributed to the knowledge about the occurrence and dissemination of the main genera/species of phytonematodes in areas cultivated with guava in southern Goiás. In addition to subsidizing new studies, it will serve as a warning to producers and make it possible to define more specific managements aimed at reducing damage by nematodes in infested areas.
