In Vitro Screening of New Biological Limiters against Some of the Main Soil-Borne Phytopathogens

This study explored the role of Aphanocladium album (strain MX95), Pleurotus ostreatus ALPO) and eryngii AL142PE) as potential biological limiters. MX95, ALPO AL142PE were screened under laboratory studies against Phytophthora nicotianae (PN), Fusarium oxysporum f. sp. radicis-lycopersici (FORL), lycopersici (FOL), solani (FS), Sclerotinia minor (SM), sclerotiorum (SS), Athelia (Sclerotium) rolfsii (AR) Verticillium dahliae (VD). The radial growth inhibition over-growth antagonists on target organisms used to assess interactions in vitro dual culture plate assay. antagonistic ability each challenge isolate was evaluated by calculating an index antagonism (AI) based interaction type cultures. reducing SS (20%) FS (40%), displayed deadlock at mycelial contact FOL FORL, distance versus VD completely over-grew PN SM. reduced (43 88%) tested pathogens except FORL replaced VD. (53 67%) SS, VD, PN. AR showed combative all experienced Based results AI values, MX95 (AI = 16.5) considered active antagonist, while 11.5) 12.0) moderately antagonists. Strains suitable environment-friendly biocontrol agents manage some main soil-borne foot, root, soft rot wilt diseases. These are first step assessment capacity these Nevertheless, additional experiments should be performed for translation field conditions plant protection pathogens. In particular, optimisation dose application time validation a solid conclusion about competitive usefulness
