Identifying Common Tree Diseases & Pest Problems

As a homeowner, you take pride in your property, and that includes the health and beauty of your trees. Unfortunately, trees can fall victim to various diseases and pests, which can cause significant damage if not addressed promptly. In this blog post, we will discuss five common tree diseases and pest problems in Louisville, KY, and how to identify and treat them. By staying informed and vigilant, you can protect your trees and ensure they remain healthy and thriving for years to come.

1. Emerald Ash Borer

The Emerald Ash Borer (EAB) is a highly destructive, invasive beetle that attacks and kills ash trees. The adult beetles are metallic green and about ½ inch long. They lay their eggs on the bark of ash trees, and the larvae bore into the tree, disrupting the flow of nutrients and water, eventually killing the tree.

  • Identification: Look for D-shaped exit holes, thinning canopy, and increased woodpecker activity.
  • Treatment: Contact a professional tree care service for proper diagnosis and treatment options, which may include insecticides or tree removal.

2. Anthracnose

Anthracnose is a fungal disease that affects various tree species in Louisville, KY, including sycamore, oak, and maple trees. It causes leaf spots, twig dieback, and defoliation, which can weaken the tree and make it more susceptible to other problems.

  • Identification: Look for irregular, brown leaf spots and dead twigs or branches.
  • Treatment: Prune affected branches, rake and dispose of fallen leaves, and consider applying a fungicide. Contact Abundant Tree Care Services, LLC, for expert advice and treatment options.

3. Dutch Elm Disease

Dutch Elm Disease (DED) is a devastating fungal disease that affects elm trees. It is spread by elm bark beetles or through root grafts between neighboring trees. DED causes wilting, yellowing, and browning of leaves, and can eventually kill the tree.

  • Identification: Look for wilting leaves, yellowing or browning of leaves, and streaking in the sapwood.
  • Treatment: Prune and dispose of affected branches, and consider injecting the tree with a fungicide. Contact a professional for a proper diagnosis and treatment plan.

4. Bagworms

Bagworms are caterpillars that feed on the foliage of various tree species, including junipers, arborvitae, and spruces. They construct a protective bag made of silk and plant material, which can make them difficult to spot. Heavy infestations can cause defoliation and tree stress.

  • Identification: Look for spindle-shaped bags hanging from branches and defoliated areas on the tree.
  • Treatment: Handpick and destroy bags, or apply a pesticide when caterpillars are active. Consult with Abundant Tree Care Services, LLC, for proper timing and treatment options.

5. Apple Scab

Apple Scab is a fungal disease that affects apple and crabapple trees. It causes dark, velvety spots on leaves and fruit, and can lead to premature leaf drop. Repeated infections can weaken the tree and reduce fruit production.

  • Identification: Look for dark, velvety spots on leaves and fruit, and premature leaf drop.
  • Treatment: Rake and dispose of fallen leaves, prune to improve air circulation, and consider applying a fungicide. For expert advice and treatment options, contact a professional tree care company.
