Weather conditions are good for the spread of Powdery Mildew. Powdery does best in overcast and warm weather. Shady canopies in Shiraz and Chardonnay further assist the spread of the disease.
Many hours during recent days and nights have had temperatures between 20 - 28C - this means that the temperature for powdery has been ideal favouring maximum production of spores.
