Bioefficacy of antagonist on mycelial growth of Rhizoctonia bataticola by dual culture technique

Abstract

All the four fungal and two bacterial bio agent evaluated under in-vitro were found antagonist against R. bataticola, however T. harzianum was found most effective and recorded highest mycelial growth inhibition (78.43) percent of the test pathogen over untreated control. Second and third best antagonistic found were T. viride1 and T. viride2 which recorded mycelial inhibition of 69.41 and 65.49 percent respectively. The bacterial antagonist and B. subtilis and P. fluorescens was found fungistatic recorded 53.34 and 51.76 mycelial inhibition percent respectively.
