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
