Abstract

plants showing symptoms of root-knot nematode infestation were observed in the municipality of Agudo, Rio Grande do Sul state, Brazil. Based on morphological observation, esterase phenotypes, and molecular analyses of rDNA-ITS and D2-D3 regions of 28S rDNA, the causal agent of the observed symptoms was identified as . Pathogenicity of was confirmed by fulfilling modified Koch's postulates. To our knowledge, this is the first report of in in Rio Grande do Sul State, Brazil.
