a Mycelial Growth Inhibition (MGI; %) for Macrophomina phaseolina isolate CCIBP-Mp1 and Rhizoctonia solani isolate CCIBP-Rh1 were obtained by dual culture assays on PDA at 30 °C for 7 days in darkness. Data represent the average of twelve Petri dishes for each BCA or control ± the standard error of the means. b For each pathogen, significant differences between treatment means of MGI are given by a critical value for means comparison [HSD0.05 = 6.7 and 8.5% for M. phaseolina and R. solani, respectively] according to Tukey’s honestly significant difference (HSD) tests at p = 0.05.
