Mildews:  what drives an epidemic?

Barbara Hall, South Australian Research and Development Institute (SARDI)

Powdery mildew and downy mildew are two of the top foliar disease of grapes, and an ever-enduring issue to manage.  The biology of both is well known, and the control measures well documented.  But sometimes they just seem to get away from us. So what drives epidemics?  Weather?  Resistance?  Spray techniques? The presentation will present case studies of the “one’s that got away” and why.
