Abstract : Artificially wounded mango fruit still attached to the tree formed calluses whether inoculated with C. gloeosporioides [Glomerella cingulata] or not. No typical lesions were observed on unwounded, attached fruit until they were fully ripened. The fungus survived the latent period in the form of appressoria and hyphae. Unwounded, mature, green fruit inoculated while still attached produced anthracnose lesions 3 days after picking and incubating under room conditions. In parallel experiments in the lab. with detached fruit typical lesions developed on wounded, immature fruit 4 days after inoculation; on wounded, mature, green fruit after 48 h, and on wounded, ripe fruit after 24 h. With unwounded, detached fruit lesions developed on immature ones in 13 days, on mature, green fruit in >8 days and on ripe fruit in 4 days.
