Resumo: | The nematodes of the genus Meloidogyne have broad geographic distribution and broad range of hosts, Meloidogyne incognita being one of the most widespread species, limiting the agricultural production of the western Paraná. The infesting plants that grow along ace crops, besides competing for essentials factors can multiply the inoculum and ensure high nematode densities, affecting management practices. The objective of this work is to playback M. incognita infesting plants in western Paraná and check the reaction of these plants to the nematode. A total of 10 species, where each plant was inoculated with a suspension of 5.000 eggs/J2 (Pi). After 60 days, up the gall index (GI), number of eggs/SR (Pf), reproduction factor (RF), reproducibility index (RI) and degree of resistance (GR). The trial was conducted in a completely randomized design with ten replicates, a control without inoculum and a tomato plant. The values were transformed to  where they were subjected to analysis of variance. Evaluating the gall index (GI), plants Leonorus sibicurus , Malvastrum coromandelianum and Solanum americanumshowed higher values than the others treatments. Regarding EGGS/SR (Pf), the species that showed higher values were Malvastrum coromandelianum, Conyza canadensis, Euphorbia heterophylla and Cenchrus echinatus , however, to evaluate the FR all behaved as resistant. Regarding the rate of reproduction, all species showed IR between 1% and 10%, behaving as very resistant (GR).
