Leaves have a silvery appearance; if infection is severe the leaves may curl upwards and become necrotic
Death of individual limbs or entire tree may occur
Fungal fruiting bodies appear on the surface of the dead bark
Pathogen is spread via spores released after rainfall during periods of high humidity and can enter trees through pruning wounds; risk of infection is increased if tree is pruned during late winter or early spring; trees also susceptible when they are heavily pruned
Control of silver leaf disease is difficult and infection can be widespread after rainfall in areas where the disease is present
Strategies to reduce the incidence of the disease include: removing all plant debris e.g.
pruning waste, stumps, and logs; pruning tree during dry periods and treating large pruning wounds with fungicidal dressing
