a–c Effect of different concentrations of an organic solvent extract of cell-free supernatant (CFS) of Ochrobactrum ciceri on the growth of Macrophomina phaseolina after incubation of 3 days at 30 °C. a Effect of chloroform extract on fungal biomass; b effect of ethyl acetate extract on fungal biomass. c Percentage decrease in fungal biomass over control. Vertical bars show standard errors of means of three independent biological replicates (n = 3). Values with different letters at their top show a significant difference (p ≤ 0.05) as determined by the LSD test
