Nematodes associated with sugarcane in sandy soils in Paraná, Brazil
Nematropica 40 (1), 111-119
Abstract: The aim of this study was to identify and quantify phytonematodes in sugarcane cultivated in sandy soils in ten municipalities in northwestern Paraná state, Brazil. In total, 74 samples of soil and roots in the rhizosphere of sugarcane were collected. In roots, the most frequently observed genus was Meloidogyne, found in 96.8% of the samples, followed by Pratylenchus (85.3%), and Helicotylenchus (31.3%). In soil, the most common genus was Pratylenchus, found in 94.3% of the samples, followed by Meloidogyne, Helicotylenchus and Xiphinema. Trichodoridae (Paratrichodorus and Trichodorus), Aphelenchus, Hoplolaimus, Mesocriconema and Hemicycliophora were less common. Pratylenchus zeae was present in 73% of the material examined and P. brachyurus in 13.5%. Helicotylenchus dihystera was found in 68.8% of the samples and was the only species within this genus identified.
