Abstract
In this study 284 isolates were isolated of apple trees' rhizosphere from Iran and 128 isolates were obtained from the collection of Research Department of Biological Control of University of Tehran. Four strains (P60, P61, P96, and P97) of Pseudomonas fluorescens were selected for greenhouse trials. The results of greenhouse trials showed dipping the crown and root of apple seedlings (MM106) combined with soil drench was more effective than dipping the crown and root on reducing the disease. After 6 weeks, strain P60 in dipping method combined with soil drench with 70% control, exhibited greatest effect on reducing the crown and root rot and was more effective than the fungicide metalaxyl-mancozeb. After 12 weeks, strains P60 and P96 in dipping method combined with soil drench with 55.6% and 44.5% control respectively, exhibited greatest effects on reducing the diseases Study of media on growth rate populations of effective strains exhibited that the beet molasses yeast extract (1:1) had more effect than nutrient broth(NB) medium. The initial high populations of powder formulations of strains P60 and P96 decreased during the storage at 4 and 25 degrees C over a 150-day period. In addition, formulations of strains stored at 4 degrees C had longer shelf life than those stored at 25 degrees C. In glasshouse trials, after 6 weeks, formulation of strain P60 and unformulated P60, obtained from NB medium and formulated P60, obtained from molasses yeast extract medium, and metalaxyl-mancozeb had highest effect on reducing the disease on apple rootstocks. After 12 weeks, formulation of strain P60 and unformulated bacteria obtained from both media, and metalaxyl-mancozeb with 57.1% control showed greatest effect on reducing the disease.
