Stem-End Rot
Stem-end rot is decay that begins around the stalk attachment of harvested fruit and may extend into the flesh during ripening. Several fungi can be involved in mangoes, including species associated with latent infections and wounded tissue. Sound-looking fruit at harvest can therefore develop symptoms later. Gentle handling, appropriate sanitation, and suitable storage help reduce losses, but the name alone does not identify the exact organism. Do not confuse normal sap staining with progressive soft decay around the stem.
