Abstract:

Chrysanthemum flower (Chrysanthemum morifolium Ramat.) is popularly designated as “Queen of the east”, or autumn queen (as its bloom in November-December) (Shibata, 2008; Teixeira et al., 2013). In terms of global ornamental market value, its stands to the second position after rose. Vascular wilt caused by Fusarium oxysporum f. sp. chrysanthemi is one of the most devastating disease attacking all the growth stages from nursery to flowering(Pinto et al., 2010).Bio-efficacy of five bio-control agents namely Trichoderma harzianum, T. hamatum, T. viride, T. asperellum and T. virens were evaluated in-vitro against F.oxysporum f.sp. chrysanthemi, using dual culture technique on PDA and also pot condition. However, T. viride was found to be most effective antagonist in lab followed by T. harzianum, T.hamatum, T. virens and T. asperellum. Highest percent growth inhibition of pathogen recorded by T. viride (69.53%) and T. harzianum (63.60%). Meanwhile T. asperellum (36.33%) showed least inhibition. Under greenhouse condition T. viride was found to be most effective and resulted the lowest disease severity (32.0 %) with highest inhibition(59.05 %) in compared to control, which was followed by T. harzianum, T. virens and T. hamatum. However, the soil treatment with T. asperellum was found to be least effective and resulted highest disease severity (60.0 %) of plants with lowest percent inhibition (29.04%).
