Bio efficacy of bioagents against Ceratocystis fimbriata ELL. & Halst and Fusarium oxysporum Schlecht causing wilt of pomegranate

Abstract

Wilt disease of Pomegranate caused by Ceratocystis fimbriata and Fusarium oxysporum is becoming a serious threat in recent years. In order to find the preventive measures, efficacy of seven different fungal bioagents and five bacterial antagonists were evaluated under in vitro condition. Among all bioagents, Trichoderma viride showed maximum mycelial inhibition (87.55%) of C. fimbriata followed by T. harzianum isolate 69 (83.53%). Whereas against F. oxysporum, maximum inhibition was observed in T. koningiopsis (71.43%) followed by T. viride (67.86%) and T. asperillium isolate 07 (67.86%). Among bacterial antagonists, Bacillus amyloliquifaciens gave maximum inhibition of 76.31% and 60.71% against C. fimbriata and F. oxysporum, respectively.
