Abstract

During present investigation it is observed that Biopriming a new technique that integrates biological (inoculation of seed with beneficial organism to protect seed) and physiological aspects of disease control used as an alternative method for controlling many seed and soil borne pathogens. It is an ecological approach in which selected fungal antagonists used against soil and seed borne pathogens. Biological seed treatments provide an alternative to chemical control with additional benefits of induced diseases resistance, ecofriendly nature and sustainable disease management. Mungbean (Vigna radiata) is susceptible to seed-borne pathogens, causing significant yield losses. Biopriming, a non-chemical seed treatment, was evaluated for its efficacy in managing seed-borne pathogens. Trichoderma viride, Trichoderma harzianum, Pseudomonas fluorescens and Bacillus subtilis are different bio control agents frequently used for biopriming treatment in present investigation. Also it shows reduction in disease incidence, increase seed germination and seedling vigour

Keywords

Biopriming, Mungbean, Seed-borne pathogens, Trichoderma harzianum, Pseudomonas fluorescens, Bacillus subtilis

Conclusion

Among all the seed biopriming treatments, seed biopriming with Trichoderma harzianum + Pseudomonas fluorescens @ 5 g each/kg seed recorded lowest seed mycoflora, increasing seed germination and seedling vigour index in naturally infected seed as well as artificially inoculated seed with all seed borne Fusarium oxysporum, Colletotrichum lindemuthianum, Alternaria alternata, Aspergillus niger, Aspergillus flavus, and Penicillium spp
