Compost, e.g. hardwood bark, is rendered suppressive to plant pathogens, such as Rhizoctonia solani, Pythium ultimum and Fusarium, and/or diseases caused thereby by adding to the compost, desirably after peak heating has been achieved but before substantial recolonization of the compost by mesophilic microorganisms has occurred, one or more microorganisms antagonistic to the plant pathogen. Container media also is rendered suppressive to plant pathogens and/or diseases caused thereby by amending the media with the just-described prepared suppressive compost or, alternatively, by amending separately with the compost and with Trichoderma fungus and antagonistic bacterium separately or mixed together. Desirably, the inoculated antagonistic microorganisms comprise Trichoderma hamatum species A.T.C.C. No. 20765 or 20764, together with Xanthomonas maltophilia bacterium species A.T.C.C. No. 53199 or a Flavobacterium balustinum isolate 299, A.T.C.C. No. 53198 species, A.T.C.C. No. 53198.
A method for producing a container medium which is suppressive to at least Rhizoctonia solani and Pythium ultimum and/or diseases caused thereby, which method comprises:
A biologically pure culture consisting essentially of any one or more of the following microorganisms:
A biologically pure culture for inducing suppression of plant pathogens and/or diseases caused thereby, which said culture consists essentially of at least one Trichoderma fungus selected from the group consisting of Trichoderma hamatum isolates 382, A.T.C.C. No. 20765, and 599, A.T.C.C. No. 20764 and at least one bacterium selected from the group consisting of:
