Colletotrichum gloeosporioides is a pathogenic fungus that affects various plants, including avocado. This fungus produces conidial spores in structures called acervuli, which emerge from infected tissues. Spores are dispersed mainly by splashing water and wind, finding new wounds or vulnerable tissues in which to germinate. Under favorable conditions of high humidity and warm temperatures, spores germinate and form appressoria that penetrate plant tissues. Once inside, the fungus colonizes the cells, causing necrosis and tissue death. As the infection progresses, more acervuli develop in the dead tissues, repeating the cycle. This process can be rapid, being completed in a few days under ideal conditions, which facilitates the spread and establishment of the pathogen in new areas.
