    Notes: Abstract Three fluorescent pseudomonads isolated from rhizosphere/rhizoplane of crop plants showed in vitro antibiosis against seven fungal and two bacterial plant pathogens on iron-deficient KB medium. Seed bacterization of chick- pea (Cicer arientinum L.), egg plant (Solanum melongena L.), soybean (Glycine max Merr.) and tomato (Lycopersicon esculentum Mill.) with these organisms showed an increased seed germination, shoot height, root length, fresh weight, dry weight and yield. Seed bacterization with one of these strains, RB 8, reduced the number of chick-pea wilted plants in wilt-sick (Fusarium oxysporum f.sp. ciceris) soil. Addition of iron into the soil eliminated the disease suppression. The disease suppression and/or growth enhancement along with the positive root colonization by these organisms indicate their possible use as plant growth-promoting rhizobacteria (PGPR)/biocontrol agents against chick-pea wilt.
