Description
Summary:To survey rhizosphere actinomycetes as potential biocontrol against fungal disease of passion fruits, rhizosphere soil of the plant were used as an isolation sources. Twenty five strains were assigned to Streptomyces-like strain based on morphological properties of spore chain. Four strain with distinguishing characteristic based on the macroscopic appearance of colonies on different media, were recovery from rhizosphere soil of passion fruits plant suggesting that various Streptomyces spp. grow surrounding of plant roots. On an agar medium, four strains (11.43%) commonly formed a clear growth-inhibition zone against fungal pathogen of passion fruits, Fusarium oxysporum f.sp. radicalix passiflori (FORP), indicating that this strains can produce antifungal substances. The present results indicate that four strain are a suitable candidate for the biocontrol of fusarium wilt.
