This is a fungal disease that attacks the foliage of currants, (black, red and white) and gooseberries in summer, and can be troublesome in some seasons and gardens.
This disease, which is caused by the fungus Drepanopeziza ribis (syn. Pseudopeziza ribis), can affect black, red and white currants and gooseberries and also occurs occasionally on ornamental Ribes species.
The first symptoms appear on the leaves in early summer (usually about June):
Some cultivars show some resistance:
Blackcurrant ‘Ben Connan’ AGMBlackcurrant ‘Big Ben’ Blackcurrant ‘Black Reward’ Blackcurrant ‘Ben Gairn’ (also resistant to reversion virus)Blackcurrant ‘Ben Hope’Redcurrant ‘Rondom’
No fungicides are currently available to gardeners for control of this disease.
The fungus overwinters on fallen leaves in the form of fruiting bodies which can withstand severe winter conditions. The following spring these structures produce spores of a different type from those formed on the plant in the summer. These spring spores attack the young leaves to start the infections for that season. Once the disease is present on the bush, it is spread further by the rain-splashed summer spores produced on the leaf spots.
Leaf spot is usually most severe on weak bushes, and the premature leaf fall reduces their vigour still further. The disease is also often troublesome on bushes growing on light soils.
