Fruit rot is one of the most destructive diseases of Capsicum chinense Jacq., popularly known as Bhoot jolokia or King Chilli an export oriented crop in North East India. Morpho-cultural characterization of the isolated fungal pathogen from diseased fruit identified the pathogen as Colletotrichum gloeosporioides (Penz.) Penz. and Sacc. Pathogenicity test further confirmed its association with the disease. A few bacterial and fungal microbial biocontrol agents (MBCAs) were screened in vitro against C. gloeosporioides as a potential solution in organic and integrated crop management practices. Among all the MBCAs Bacillus subtilis LB22 showed highest inhibition (85.00%) on mycelial growth of the pathogen followed by P. fluorescens (84.33%) and B. vallismortis (83.22%). Trichoderma pseudokoningii were recorded the lowest inhibition (53.22%). Our study put forth further exploration B. subtilis LB22 (NCBI accession no. ON386193 and NBAIM accession no. NAIMCC-B-03226) in planta and their response in disease suppression as well growth promotion in Bhut jolokia as a component of sustainable crop health management program. [ABSTRACT FROM AUTHOR]
