Abstract

In this study antaginistic effects of some bacteria isolated from MULBERRY tress were assessed against FUSARIUM SOLANI, Fusarium oxysporum and Lasiodiplodia theobromae under laboratory condition. Five bacterial isolates were able to suppress the fungal growth at the rate of 1-5 mm on PDA. Four of the bacterial strains (H1, H16, H24, H25) were identified as Bacillus spp. and the strain H4 was assigned as Pseudomonas fluorescence. The volatile metabolites released from antagonistic bacteria could inhibit the growth of fungi FUSARIUM SOLANI, Fusarium oxysporum, Lasiodiplodia theobromae at the rate of 25 to 35, 36.11 to 47.35, 25.18 to 76.66 percent, respectively. H4 strain produced sidrophore on King B medium which contained 5, 50, 100 mmol Fecl3 which inhibited the mycelial growth of the GEOTRICHUM CANDIDUM. The extracellular extracts of selected antagonists reduced the vegetative growth of pathogenic fungi by increasing the extracts concentration. In addition antagonistic bacteria could produce antibiotic substances which led to stop the fungal growth.
