Anthracnose, caused by the fungi Colletotrichum acutatum and C. gloeosporioides, is a widespread and severe disease in most olive-growing countries, causing significant yield losses, poor fruit and oil quality. The disease incidence depends on olive variety, environment and virulence of the pathogen among other factors. Warm, rainy, misty and humid conditions or heavy dews have been observed to be associated with severe anthracnose epidemics. The disease may affect up to 80% of olives in susceptible cultivars such as ‘Barnea’ and ‘Manzanillo’ in Australia.
