Control of strawberry powdery mildew under protection

This factsheet describes the symptoms and life cycle of strawberry powdery mildew and how it becomes established and spreads through crops grown under protection. It also provides guidance on management strategies to minimise the risk of damaging epidemics developing. 

Powdery mildew on strawberries in the UK was first reported in the 1850s. However, it was not a major pathogen at that time. 

A combination of correct tunnel management, disease monitoring and use of crop protection products is required to maintain control.
