Downy mildew

Downy mildew is a major disease of grapevines caused by the fungus Plasmopara viticola. This species is unique to grapevines and is established in all Australian grape growing districts.

The fungus is spread by wind and water and favourable conditions for infection and disease development occur in warm wet weather, especially in late spring and early summer.
