Factsheet 17/08 details the symptoms and lifecycle of the disease, caused by the fungus Podosphaera aphanis, and how it establishes. The factsheet provides advice on minimising the risk of epidemics taking hold of the UK crop.
The report details an early warning system that predicts risk days, sending an alert after 144 hours of temperature and humidity levels that cause disease development.
The system is the focus of LINK project SF94. Once developed into a user-friendly format, crop managers will be sent notice of optimum conditions to ensure appropriate treatments are made in time.
