The causal agent of bacterial stripe disease of pearl millet (Pennisetum glaucum) in Nigeria was identified as Pseudomonas avenae. Most strains of P. avenae obtained from culture collections and all six strains from pearl millet were positive for acid production from arabinose, fructose, galactose, glucose, glycerol, and sorbitol. None of the strains utilized sucrose as the sole source of carbon, but most utilized citrate and all grew at 41 C. In the greenhouse, all strains of P. avenae were pathogenic in corn, millet, and sorghum and most were pathogenic in sugarcane.
