Abstract
Several species of the genus Curvularia had been registered on rice causing damages, particularly grain spots and discoloration; however there have not been made studies to demonstrate the pathogenicity of the registered species in Cuba. Conidial suspensions of 13 species of Curvularia from rice seeds: C. aeria, C. akaiiensis, C. andropogonis, C. brachyspora, C. cymbopogonis, C. geniculata, C. intermedia, C. lunata, C. pallescens, C. senegalensis, C. trifolii, C. verrucosa and C. verruculosa were sprayed on 15 days old plants of three rice varieties which were evaluated with a qualitative scale of damages later. It was corroborated the pathogenicity of C. lunata and C. geniculata and the symptoms caused by the remaining species is reported and discussed.
