Abstract: Stem end rot (SER) is a fungal disease complex that poses a major threat to the delivery of quality mangoes from Pakistan to export markets. The dynamics of this disease remain unclear, butmust be elucidated so that effectiveness of disease management can be improved. The present study sought to describe the infection process and delineate a disease cycle of SER under Pakistani growing conditions. Our study discovered three possible routes of infection that could lead to SER: 1) infection at bloom stage; 2) the pathogen may be endophytic within the twigs and branches; and 3) airborne spores of the pathogen invade the pedicels and xylem and then grow into the ripening fruit. Culturing of symptomatic samples from selected orchards revealed colonization by five fungal pathogens, of whichLasiodiplodiatheobromaewas most prevalent. A pathogenicity assay revealed that all five pathogens were pathogenic to mango fruit when inoculated artificially.The efficacy of fungicides -Cabrio Top®, Nativo®, Scholar®, Tecto®, Amistar®, and Sportak®at several concentrations was evaluatedagainst SER pathogensin vitroand in vivo. Results indicated that Nativo®, and Cabrio Top®, at 250 μg/mL provided statistically significant suppression of mycelial growth and SER development as compared to other tested fungicides
