A study led by the University of Córdoba's Department of Agronomy, in collaboration with international partners, has identified 12 species of the fungus Colletotrichum, which causes anthracnose in olive trees and other crops. The research, which analyzed 185 isolates from various locations including Spain, Australia, Brazil, and Italy, over a period of 25 years, aims to improve understanding of the pathogen to develop effective control strategies. The study found that the species diversity was highest in Australia and that the dominant species in different regions varied in virulence and sensitivity to fungicides, highlighting the need for site-specific control measures. The findings are published in the journal J. Fungi.

The Department of Agronomy of the University of Córdoba leads an international study in which the different species of the pathogen are glimpsed thanks to the samples collected over 25 years. The olive tree is one of the most important woody crops in the world, whose cultivated area occupies more than 11 million hectares (FAO, 2019). Due to its economic, social and cultural importance, the study of the pathogens that affect the tree and the fruit is decisive to find control methods that prevent damage. Among the foliar diseases that affect the olive tree, anthracnose is considered one of the most important. This disease, popularly known as "soapy olive", is caused by species of fungi of the genus Colletotrichum, and causes high losses in fruit yield and oil quality during epidemic years. This is why a team from the María de Maeztu Unit of Excellence - Department of Agronomy of the University of Córdoba (DAUCO) has conducted an international study that collects the specific ...
