Meloidogyne incognita parasitizing Ophiopogon japonicus in Rio Grande do Sul state, Brazil.

Abstract

Ophiopogon japonicus plants showing symptoms of root-knot nematode infestation were observed in the municipality of São Vicente do Sul, Rio Grande do Sul state, Brazil. Based on the morphological identification, esterase phenotypes and molecular analyses of COII and 16S region, the causal agents of the observed symptoms were identified as Meloidogyne incognita, with pathogenicity confirmed by fulfilling Koch's postulates. This is the first report of M. incognita in O. japonicus in Brazil.
