Colletotrichum gloeosporioides is a pathogenic fungus that causes anthracnose disease in mangoes. Anthracnose is a common fungal disease affecting various plant species, and in mangoes, it leads to the development of dark lesions on leaves, stems, and fruit. The disease can result in significant economic losses for mango growers due to reduced fruit quality and yield. Proper disease management practices, including the application of fungicides and good orchard hygiene, are essential to control anthracnose in mango crops.
