The Problem

Downy Mildew

Downy mildew is a group of fungal diseases that affect a wide range of plants. Symptoms include dark patches on top of the leaves, often with corresponding furry or downy growth on the undersides. These tufty growths may be purplish in colour. Downy mildew occurs in humid conditions and affects vegetables, fruits and ornamental shrubs and flowers. Susceptible plants include roses, hebes, lettuce, cucurbits, grapes rhubarb.

Reduce the risk of disease developing by growing plants in open positions with good air circulation. Avoid watering over leaves. When applying a fungicide, take special care to contact the undersides of leaves.
