Olive Leaf Spot

• circleCircular dark grey to black spots on leaves, often ringed with yellow (a 'peacock eye' pattern)
• circleYellowing and premature drop of affected leaves
• circleSparse canopy and reduced fruiting over time

Caused by the fungus Venturia oleaginea (formerly Spilocaea oleagina, also known as peacock spot), favored by mild, wet weather in autumn and spring.

Remove fallen infected leaves, prune to improve air circulation through the canopy, and apply copper-based fungicide in autumn and spring in high-risk areas.

Prune regularly to keep the canopy open, avoid overhead irrigation, and apply preventive copper sprays before wet seasons in areas with a history of infection.
