In vitro bioefficacy of bioagents against Alternaria alternata causing fungal fruit rot in pomegranate

Abstract

In vitro bioefficacy of different bioagents against Alternaria alternata causing fungal fruit rot in pomegranate were carried out at the Department of Plant Pathology, College of Agriculture, Latur during the year 2017-18. Among the different fungal and bacterial bioagents T. harzianum was found most effective with least mycelial growth (14.66 mm) and numerically highest mycelial inhibition (82.11%), followed by T. virens (16.66 mm and 80.07%), T. hamatum (18.66 mm and 77.96%), T. asperellum (21.33 mm and 75.44%), A. niger (29.33 mm and 66.18%), P. fluorescens (43.00 mm and 53.14%), B. subtilis (52.00 mm and 41.74%) and T. koningii (52.33 mm and 41.01%). The bioagents were evaluated in vitro against the pathogen Alternaria alternata causing fungal fruit rot in pomegranate by dwell culture technique. Among the in vitro evaluated all bioagents T. harzianum, T. virens, T. hamatum,and T. asperellum were found more efficient while A. niger, P. fluorescens, B. subtilis and T. koningii, were least effective against Alternaria alternata major fungal pathogen causing fruit rot in pomegranate.
