Among 18 isolates, SDSRO-13 showed strong inhibition against <em>Colletotrichum </em>spp. of chilli. SDSRO-13 was identified as <em>Streptomyces</em> sp. based on morphological, biochemical and 16S rRNA partial gene sequence analysis. In this study, two strains of <em>Colletotrichum</em> sp. were used for pathogenicity test. For <em>in vivo</em> antifungal activity, spore suspension of the test pathogens were used on the fresh chilli fruit by making a small puncture on the fruit, in completely sterile conditions and incubated for up to 21 days. The chilli fruits treated with SDSRO-13 and test pathogens showed no disease symptoms. The infected fruits were subjected for Koch’s postulate test and they showed the similar morphological features compared to the pure cultures of the pathogens.&nbsp; We conclude that Actinomycetes, especially members of the genus <em>Streptomyces</em> are potential biocontrol agents which offer safer alternative management strategy to control the chilli fungal pathogens.</p>}, number={2}, journal={Journal of Spices and Aromatic Crops}, author={Savita, D S and Onkarappa, R}, year={2023}, month={Dec.}, pages={170–185} }
