Pests and Diseases

Black vine weevil and strawberry weevil adults feed at night, notching the leaf margins and making holes in the leaves. The larvae feed on the roots and bark, girdling and killing the plant.

Lace bugs cause leaf yellowing, particularly when plants are heated in too much sun. Brown specks on the undersides of leaves are insect excrement. Sunny sites may lead to higher lace bug populations.

Mites cause leaf discoloration.

Scales may be found on branches and stems of unhealthy looking plants. Use dormant oil in spring.

Gray blight infection follows an injury, such as winter injury. A spot, which is at first white with a dark brown margin, forms on the leaf. Protect plants from winter injury.

Dieback is also called Botryosphaeria canker. The leaves are attacked near the tips or at the margins; then spots form on the entire leaf. Leaf stalks and twigs are eventually infected. Prune off infected parts.

Leaves infected with Phytophthora dieback turn brown, roll, then drop off. The stem shrivels and a canker forms, eventually girdling the stem. Prune out diseased branch tips.

Powdery mildews of different genera form a white coating on the leaves.

Leaf spots may be caused by any number of fungi.
