Effectiveness of the Chemical Stabilizers of Talaromyces Flavus in Biological Control of Tomato and Greenhouse Cucumber Pythium Root Rot Disease

In Iran, considerable research have been already carried out, about the mass production of the different Talaromyces flavus isolates and their efficacy in controlling some important soil borne diseases, in several crops have been also investigated. For the application of these biological products in the fields, the technical science related to their production should be assigned to the producer companies. In this study, according to the specific metabolites, related to these mechanisms, the stabilizers of these metabolites were used in developing bioformulations, containing T. flavus isolates. Based on the previous studies, the effective substrate in terms of the sporulation and the efficacy of T. flavus isolates, was rice bran-peat moss. Results showed that, two T. Flavors bioformulations related to dicycloserine and carboxymethyl cellulose, bioformulation containing carboxymethyl cellulose was more effective, than dicycloserine in controlling above-mentioned pathogenic agents, for treatments related to tomatoes; however, this position was reversely for greenhouse treatments.
