摘要
Plants of Cereus jamacaru with root necrosis symptoms were observed in Acopiara City, in the state of Ceará, Brazil. Using morphological characterization and molecular analysis of the ITS and 28 S rDNA regions, Pratylenchus zeae was identified as the etiological agent, confirmed by infection and re-isolation of the nematodes. This is the first report of P. zeae causing root necrosis symptoms in C. jamacaru.
