Title: Biological control of Sclerotium rolfsii sacc. in peanut by inoculation with Pseudomonas fluorescens
Abstract: Native strains of Pseudomonas fluorescens were examined for their ability to suppress the root and stem rot pathogen of peanut, Scterotium rolfsii. P. fluorescens restricted the mycelial growth of S. rolfsii in in vitro plate tests. Sclerotia showed 10–20% and 50–60% germination losses after they were immersed in a bacterial cell suspension for 1 h and 1 week respectively. In greenhouse experiments, 99% of peanut plants were protected from S. rolfsii infection if they were inoculated with P. fluorescens (108cfu ml−1). Non-bacterized S. rolfsii-infected plants wilted or died in 10 days and fresh weights of tops of these plants were significantly lower than those of plants inoculated with bacteria infected with S. rolfsii.
