Raspberries: Leaves, especially the lower leaves, have spots on them

Leaf spots occur most commonly on the lower portion of canes where conditions are favorable for disease development. Canes may also be infected – cane lesions are similar to those on leaves but more elongated in shape. Varieties differ in their susceptibility to leaf spot diseases. Eventually leaf spot infected leaves may turn yellow, brown, then drop off the plant.

The Raspberry Leaf Spot fungus (Sphaerulina rubi) causes typical frog-eye leaf spots with whitish centers and darker margins.

There are brown, dry spots present on yellow-discolored leaf sections. One leaf tip and outer margin is entirely dry and brown before transitioning to yellow tissue with brown spots.
