Abstracts |
Gaeumannomyces graminis var. tritici is the causal agent of take-all disease of wheat, the most important damaging root disease is very important in North, Central and Southwest Provinces of Iran and worldwide. Piriformospora indica and Sebacina vermifera, which are a newly discovered arbuscular mycorrhiza-like fungus. They are a facultative symbiont and unlike arbuscular mycorrhizal fungi, can be cultured in vitro. Trichoderma harzianum and T. viride are efficient biocontrol agent that is commercially produced to prevent development of several soilborne pathogenic fungi. Interactions between P. indica, S. vermifera, T. harzianum strain 100, T. viride and soilborne fungi of Gaeumannomyces graminis var. tritici were investigated separately and in combination on PDA and Kafer medium. Opposing (Dual culture) cultures as well as colonization studies showed that the species of P. indica, S. vermifera, T100, T. viride with could produce a good zone of inhibition. Volatile metabolites test between Trichoderma species and Ggt inhibitory effects on growth Ggt mycilium. These fungal species are the most potent agents for the biocontrol of soilborn plant pathogen. |
