The test was carried out to see the effect of the Bacillus isolates on the fungi before the growth of the fungi in vitro. Fungal inhibition tests were performed by plate assay. A loop of Bacillus culture was streaked over the surface of a PDA plate (Biolab) and after 4 days of incuba- tion at 28°C, each Petridish was inoculated with a loopful containing mycelia of F. solani. Petridishes were then incubated at 25°C for 10 days and examined for inhibition of fungus growth by the Bacillus isolates. A zone of inhi- bition around the Bacillus isolate indicated posi- tive response. The width of cleared zones of an- tagonism (distances between the bacterial and fungal growth) were measured after 10 days. Each experiment was repeated four times. The results were expressed as the mean values with standard error deviation in inhibition distance between the growths of the corresponding Fusarium isolate and the presence of the Bacil- lus isolate tested. Percentage inhibition was cal- culated as follows:
