Common Cedar Rapids Area Tree Diseases

Apple Scab

apple scabApple scab is a fungal infection that is most common in apple trees. Homeowners may see apple scab outbreaks on their apple trees after cool and wet conditions. The fungus develops over the winter on fallen leaves. Spores begin to develop in the spring. Wind and rain spread the spores onto budding leaves, twigs, and even the fruit itself. Once the fungal infection has been established in the tree, new spores develop and spread to surrounding trees.

Signs of an apple scab infection is first noticed by brownish-green spots on leaves or fruit. As the infection becomes worse, spots on fruit will become darker and take on a fuzzy texture. You may also notice yellow leaves falling from the tree as well as fruit becoming deformed and dropping prior to ripening.

Anthracnose

AnthracnoseAnthracnose, also known as leaf blight, is another fungal infection that develops on twigs during the winter. Spores are transferred to new buds and leaves during spring cool and wet conditions. Many trees can be effected by this fungus: ash, maple, elm, hickory, walnut, birch, and linden, with sycamore, white oak and dogwood being the most susceptible to anthracnose. Damage could be as severe as complete leaf loss in late spring.

Symptoms of anthracnose include tan or red-brown lesions along the veins and edges of the leaf. You may also see considerable defoliation, sometimes with complete leaf loss.

Common Cedar Rapids Area Tree Insects

Emerald Ash Borer

imageEmerald Ash Borer (EAB) is becoming more and more of a problem for Cedar Rapids area trees. EAB larva live under the bark of ash trees and feed on the vascular tissue, killing the tree from the inside out. Adult emerald ash borer beetles emerge from the tree in June, leaving D-shaped holes in the bark.

Symptoms of an EAB infection include dying leaves and branches. Also, tree bark will split over the dead vascular tissues. Untreated trees may die within two years of an infection. Keep in mind that treating trees early on will be far less expensive than having a dead tree removed.

Aphids

aphidAphids are small insects with transparent wings that can be found at the stems or underside of tree leaves. They are often drawn to new growth on trees and other plants. Aphids feed off plants by sucking the sap from stems and leaves. Some plant sap is excreted as honeydew which makes plants, patio furniture, and any outdoor surfaces have a sticky texture. Often a sticky mold will grow on the honeydew, turning plant stems, leaves or other surfaces black.
