Abstract
In the present study, fungal and bacterial antagonists were evaluated against early blight pathogen of tomato, Alternaria solani under in vitro, glasshouse and field conditions. Among the isolates tested, T. harzianum (Th-7) showed significant inhibition of A. solani under in vitro (72.78%) and glasshouse conditions (62.60%). Seedling dip and foliar applications of T. harzianum (Th-7), T. viride (Tv-14) and P. fluorescens (Pf-1) decreased the early blight incidence up to 62% and increased tomato yield up to 37% over control in field trials.
