Item Antagonistic activity of bacterial isolates against fusarium pathogens(CEP USM, 2024) Bîrsa, Maxim; Balan, Ludmila; Bogdan-Golubi, Nina; Moldovan, CristinaActinobacteria and bacteria stored in NCNM were tested against F. oxysporum CNMN-FF-06 and F. solani CNMN-FF-07. In case of antagonistic activity against F. solani, results were much higher in comparison with F. oxysporum, ranged between 12.3 – 19.3 mm. The highest result of antifungal activity of bacteria against F. oxysporum was registered for the strain Bacillus velezensis CNMN-BB-16 (25.0 mm). For F. solani, the highest result was registered for the strain Micrococcus yunnanensis CNMN-BM-19 (33.0 mm). Results of the present research had shown that biocontrol agents can be used as an alternative for chemical pesticides utilized against phytopathogenic fungi.Item Identification of mycotoxin – producing species of Fusarium in tomato ontogenesis(CEP USM, 2024-10-07) Deaghileva, AngelaThe results of molecular identification of toxigenic Fusarium spp. in local tomato varieties at some vegetative phases are presented. F. oxysporum, F. verticillioides, F. proliferatum, F. avenaceum, F. equiseti, F. solani were found at different stages of tomato development. Sequences of FUM gene cluster involved in the synthesis of Fumonisin B1 and Polyketide synthase (PKS13) gene sequences involved in the synthesis of Zearalenone were revealed in some tomato varieties infected by certain toxigenic Fusarium species.
