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. Use acephate to control black vine weevil.
Lace bugs cause leaf yellowing.
Brown specks on the undersides of leaves are insect excrement. Sunny sites may lead to higher lace bug populations. Use sprays of acephate. Mites cause leaf discoloration. Scales may be found on branches and stems of unhealthy- looking plants.
