In vitro efficacy of bio-control agents against Fusarium oxysporum f. sp. Gladioli

Abstract

Present study was carried out in the Division of Plant Pathology and Agricultural microbiology, College of Agriculture, Pune (Maharashtra) during 2019-2020. The results revealed that the all six bio-agents evaluated, exhibited antifungal activity against test pathogen and significantly inhibited the mycelial growth, over untreated control. Out of six bioagents Trichoderma harzianum showed least mycelial growth (1.10 cm) and highest mycelial growth inhibition (87.78%) followed by Pseudomonas flourescens with 1.20 cm mycelial growth and 86.67 % growth inhibition, T. viride with 1.30 cm mycelial growth and 84.92 % growth inhibition and Bacillus subtilis with 1.70 cm mycelial growth and 81.11 % growth inhibition and were found at par with each other.
