Abstract
Background: The fungal and bacterial antagonist were used to study their antimicrobial efficacy against Xanthomonas axonopodis pv. vesicatoria (Doidge) Dye in chilli causing bacterial leaf spot. Objective: The present study indicates the effective control of the pathogen and reduced the disease incidence significantly in non-hazardous manner by using fungal and bacterial antagonists. Materials and methods: For the control of pathogen 5 fungal and 2 bacterial antagonists namely Gliocladium virens, Trichoderma viride, T. harzinum, Stachybhotrys atra, Penicillium chrysogenum and Bacillus subtilis, Pseudomonas fluorescence respectively used by filter paper disc assay, seeded agar method and standard blotter methods. Results: Out of used fungal antagonists Trichoderma viride found most effective which improve seed germination and control of pathogen followed by Penicillium chrysogenum as compared to check in all the method. In filter paper method, bacterial antagonist Bacillus subtilis found effective against the pathogen followed by Pseudomonas fluorescence in control of various isolates of XAV.
Keywords: Antibacterial, chilli, fungal antagonists, bacterial antagonists, Xanthomonas axonopodis pv. vesicatoria
