Abstract

Farm yard manure fortified with bio-agents Pseudomonas fluorescens, Trichoderma asperellum and Aspergillus niger either singly or in rational combinations were evaluated against soil- borne fungal pathogens in FCV tobacco nursery. Results of the trial indicated that, application of P. fluorescens and A. niger fortified FYM @ 4 kg/ m2 recorded 40.2 per cent increase in number healthy transplants (640/ m2) and was on par with recommended chemical schedule (627.5/ m2). At 60 DAS, P.fluorescens + A. niger fortified FYM, P. fluorescens + T. viride fortified FYM and chemical check were on par with each other in recording reduced RKI of 1.97, 2.08 and 1.91 respectively compared to 3.80 as RKI in untreated check. Similarly, Bio-agents fortified FYM recorded significant decrease in damping off at 35 DAS (41.1 to 52.4%), damping off + blight at 45 DAS (44.1 to 52.9%) and black shank (45.7 to 58.3 %) compared to untreated check. Though, the chemical schedule was superior in decreasing the damping off by 90.0%, damping off + blight by 93.9% and black shank by 93.4% compared to untreated check the study infers the effectiveness of bio-agents for reducing the chemical use to minimize environmental pollution.
