A preliminary study of biological control of citrus gummosis by soil-borne Streptomyces sp. isolates in vitro condition.

摘要

In this research, the activity of antagonistic activity of 200 soil-borne Streptomycetes isolates assayed against Phytophthora parasitica and P. citrophthora in Kerman Province was investigated. Primary screening for antimicrobial activity was determined by dual culture experiments and 20 isolates showed high level of fungicidal activity in Agar disc method. The soils of Kerman are rich sources of microorganisms with potent biological activities and screening programmes are to be conducted to reveal the presence of active Streptomycetes isolates.
