Abstract
Seventeen bacterial isolates from known sources and peanut plants were tested, in vitro, for their antagonistic effect against the pathogens causing damping-off, wilt and peanut root rot. Only five isolates B. subtilis (8S) P. fluorescens (Pf 5), (Sp1), (Sp2) and (5s2) caused moderate to strong inhibition on mycelium growth to the four tested pathogens (R. solani, S. ro/fsii, F. solani and M. phaseolina). Pseudomonase fluoressens (Pf 5) followed by Bacillus subtilis (8S1) and Bacillus sp (Sp2) caused the widest inhibition zone almost to tested pathogens. In greenhouse experiment, the most effective isolates in reducing peanut damping-off, wilt and peanut root rot were P. fluorescens (Pf 5) followed by B. subtills (8S1) and Bacillus sp (Sp2).
