What is currant and gooseberry leaf spot
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.
 
Symptoms
The first symptoms appear on the leaves in early summer (usually about June):
  • Leaves become spotted with very small, dark brown or black spots
  • Later, the spots become more numerous and often coalesce so that large areas of the leaves turn brown
  • Large numbers of minute fungal spores form in fruiting bodies on these spots and may sometimes be visible as small droplets on the surface of the spots
  • When the disease is severe, the leaves fall and the bushes may become defoliated by early July
  • Sometimes the fruit shrivels before ripening
