Evaluation of some Trichoderma isolates for biological control of potato wilt disease (Fusarium oxysporum) under laboratory and greenhouse conditions
Biological efficacy of <em>Trichoderma</em> species may differ due to variations in ecosystems. This study was conducted to assess the biocontrol efficacy of some native <em>Trichoderma</em> isolates against <em>Fusarium oxysporum</em>, an important causal agent of potato wilt disease under laboratory and greenhouse conditions in Shahrood Agricultural Research Center, Shahrood, Iran during 2006-2007. Fourteen isolates were collected among which eight showed promising ability in inhibiting growth of the pathogen through dual culture and production of volatile and non-volatile metabolites but <em>T. asperellum</em> (T2) and <em>T. atroviride</em> (T3) were almost more efficient than other isolates in inhibiting the mycelial growth of the pathogen in comparison to control (<em>P </em>≤ 0.01). Eight isolates were evaluated against the disease under green house condition. Potted plants treated with <em>Trichoderma</em> isolates + <em>F. oxysporum</em> showed lower disease incidence in comparison to Fusarium infested control (<em>P </em>≤ 0.05). Best disease control was observed in potted plants treated with <em>F. oxysporum</em> + <em>T. asperellum</em> (T2) showing 2.5% disease incidence in contrast to Fusarium infested control, in which disease incidence was 73%.
