Managing Powdery Mildew

Powdery mildew is driven by the amount of inoculum (spores) inherited from last season. In much of Australian viticulture, the disease progresses more or less independent of the weather, though in cool climates, temperature may be limiting at times.

Powdery mildew is common across Australian vineyards. With a better knowledge of disease epidemiology (ie how the disease spreads), of the need to time sprays appropriately and, withimproved spray technology and an excellent array of fungicides, direct crop loss from powdery is minimal.

Managing Downy Mildew

Downy mildew is driven by the weather. The disease can devastate individual vineyards and in some seasons, affect production from regions.


To reduce the losses downy causes, reduce the number of unnecessary sprays in dry conditions and refine the timing of sprays during conditions that favour the disease. This fact sheet provides an overview of the disease, the conditions that favour each phase of its development and best management options to lessen the impact of this disease.
