Abstract


Anthracnose, caused by Colletotrichum capsici, poses a significant challenge to chilli (Capsicum annuum L.) cultivation, particularly affecting ripened fruits and leading to substantial yield and quality losses. In light of rising disease pressure and growing concerns over chemical fungicide use, this study explores the potential of Bacillus amyloliquefaciens as a sustainable biocontrol and plant growth-promoting agent. Dual culture assays revealed pronounced antifungal activity, with up to 56.8% inhibition of pathogen growth in five days. Microscopic observations showed severe hyphal deformities; while culture filtrate and volatile assays further confirmed the production of potent antifungal compounds. Beyond disease suppression, seed priming with B. amyloliquefaciens accelerated germination, stimulated root and shoot development, and thus significantly improved seedling vigour. These results thus position B. amyloliquefaciens as a promising eco-friendly solution for managing anthracnose while promoting healthier, more resilient chilli crops. Field-level validation and formulation development will further help to realize its full potential in sustainable farming.
