Antagonistic effect of ceramic industry soil streptomycesagainst plant pathogens
The various diseases that occur during the growth of plants usually cause a significant reduction in production and quality of agricultural products. Actinomycetes, especially Streptomyces spp., become a valuablebiological control resource due to their preponderant abilities to produce various secondary metabolites with novel structure and remarkable biological activity. The potassium solubilizing actinomycetes isolated from the ceramic soil industries were carried out anantagonistic effect against various soil borne phytopathogenic fungiand bacteria.
