Present investigation was carried out to examine the efficacy of different bio-agents on disease parameters and microbial population of chrysanthemum at Department of Floriculture and Landscaping, College of Horticulture and Forestry, Jhalawar. For this formulations of different bio-agents like Pseudomonas fluorescens (125g and 175g and 250g per plot area), Trichoderma harzianum Trichoderma viride, Trichoderma longibrachiatum, Bacillus subtilis used as root application. Pseudomonas fluorescens (250g) treatment was found effective and significantly affected disease management and microbial population. Plant treated with 250g Trichoderma viride had minimum number of days to first flower bud emergence (35.53 days), minimum days taken to 50 per cent flowering (65.33 days), maximum number of flower plucked (6.80) and maximum duration of flowering (32.75 days) and minimum disease incidence (10.00%), minimum mortality (10.00%), minimum per cent disease incidence (12.50%) and microbial population count after treatment application.
