Copper compounds are effective in controlling major fungal foliar and fruit diseases of olive, mainly olive leaf spot or peacock spot caused by Spilocaea oleagina, anthracnose incited by Colletotrichum spp., cercosporiose due to Pseudocercospora cladosporioides, and olive knot, caused by the bacterium Pseudomonas savastanoi pv. savastanoi. However, their effectiveness depends a great deal on the specific disease, time of application, and persistence on olive leaves and fruits.
