Three plant growth-promoting yeasts (PGPY) and two rhizobacteria (PGPR) were tested for controlling tomato wilt under greenhouse and field conditions. Before transplanting, seedlings were treated with suspension of the tested antagonistic local isolate of PGRY or PGPR. Under greenhouse and field conditions, all treatments significantly reduced disease severity of tomato wilt relative to the infected control. The highest disease reductions in pots (75.0, 67.4 %) and field (52.5, 42.4%) were achieved by Azospirillum brasilense and Bacillus subtilis in comparison with seedlings inoculated with the pathogen alone. Also, these two treatments produced the highest tomato yield compared to the control plants inoculated with the pathogen under field condition. The lowest disease reductions were caused by Candida sake and Pichia membranifaciens (40.9 and 41.0%, respectively). All inoculation treatments with tested strains scored significant increases in shoot fresh and dry weight of tomato plants compared to the infected control, and the most promotive were those inoculated with A. brasilense followed by B. subtilis.
