Eighth treatments in plots of 50 plants giving a total of 1200 strawberry plants were planted on raised bed at a spacing of 0.30 m × 0.35 m on a loamy soil with black plastic mulch in the beginning of May 2006. Application of Bacillus M3 was performed using a dipping method in which plant roots were inoculated with the bacterial suspensions of the concentration of 109 CFU ml−1 in sterile water about 30 min prior to plantation.
