Downy mildew

Is a group of fungal infections 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.

If you notice this, remove affected leaves and spray the plant weekly with a milk and baking soda spray. Or, when applying a fungicide, take special care to contact the undersides of leaves.

Downy mildew occurs in humid conditions and affects lettuce, pumpkins, cucumber and watermelons.

Reduce the risk of fungal infections developing by growing plants in open positions with good air circulation. Avoid watering over leaves.
