Abstract:
Rhizome soft rot disease caused by Pythium aphanidermatum is one of the most widely distributed and destructive disease of Ginger (Zingiber officinale Rosc.) causing about 50 to 80 per cent yield losses. Five fungal and two bacterial antagonists were evaluated under in vitro condition against P. aphanidermatum causing rhizome soft rot disease of ginger. All antagonist were found fungistatic / fungicidal action against test pathogen. Amongst the antagonist used T. asperellum was found most effective and showed significantly highest mycelial inhibition (81.72%) followed by T. harzianum and T. koningii with inhibition of 76.66 and 61.74 per cent, respectively. While the antagonist Bacillus subtilis showed least inhibition (33.33%) against the test pathogen.
