    Abstract

    Actinomycetes isolated from the organic mulch used in avocado plantations in Western Australia were studied to examine their ability to suppress Phytophthora cinnamomi. All the 1600 isolates tested inhibited the pathogen in vitro with inhibition rates of >0.5. The inhibition rates achieved by actinomycetes isolated from fresh and pathogen-infested mulch were not significantly different, but the isolates tested differed in their ability to suppress the pathogen and/or the disease. Some of the isolates that inhibited the pathogen were also harmful to plant growth.
