Abstract
|
|
|
|
Anti-fungal materials producing bacteria were isolated from soil by bennett’s agar and actinomycete isola-tion agar medium. The bacterla were identified as synonym of Actinomycetes. Based on the data obtained from its morphological and colony characteristics. The medium for production of anti-fungal materials was YEME (yeast extract 4 g, malt extract l0g, glucose 4 g, D.W 1ι, pH 7.00.2). The culture conditions were 30, 7 days and 200 rpm in shaking incubator. No. 13, No. 15 and No.28 strains were produced anti-fungal materials against fungal plant pathogens. Specially, The No. 28 strain showed a powerful biopesticide activity and broad spectrum effects of anti -fungal materials on Collectrichum coccodes, Botrytis cinerea, Cladosporium cucumerinum, Didymella bryoniae.
