Abstract

The in vitro experiment revealed that the fungicide pyraclostrobin 20% WDG at 0.1%, 0.15% concentrations and carboxin + thiram 75% WS (Vitavax) at 0.2% conc. completely inhibited the mycelial growth of Aspergillus niger and accounted for 100% inhibition of the pathogen followed by carbendazim @ 0.1% ( 98.42% ), mancozeb @ 0.2% (94.51% ) and pyraclostrobin 20% WDG at 0.5% (98.46% ). Pseudomonas fluorescens recorded the higher inhibition of the pathogen as compared to Trichoderma harzianum. The present study clearly revealed that the fungicide pyraclostrobin 20% WDG at 0.1% and 0.15% completely inhibited the pathogen A. niger.
