Fungal disease of raspberries caused by Phragmidium rubi-idaei.

OBS

Symptoms: Leaf infections in spring and early summer create a yellowish spotting on the upper leaf surface. At first the spots are very small, yellow to orange and slightly raised (spermagonia) but then new, yellow to orangish spore bearing structures (aecia) are produced in a ring around these spots. By summer, another yellow spore stage (uredinia) appears on the lower leaf surface ... Fruit often dies on the canes before maturing if leaves on fruiting laterals are attacked early in the summer.
