How to Check Your Trees for Pests

tree pests and diseases

A tree’s susceptibility to pests and diseases can differ based on the species. Start by getting to know the trees on your property and the pests that may threaten them. Check your trees for discoloration, rapid canopy thinning, irregular leaf size, and wood borer holes.

Unusual Activities

Search for any bugs or activities that seem out of place. For example, an invasive beetle infestation can kill your favorite ash trees. A large population of one bug species indicates a tree infestation.

Inspect the Tree Trunk

Carefully examine the tree trunk and branches. If the trunk appears damaged, you may have a pest problem. Trees rapidly die when tree pests and diseases burrow holes into their trunks.

How to Check Your Trees for Diseases

Trees often show disease symptoms, such as leaf spots, foliage browning, wilting, defoliation, stunted growth, and yellowing. Tree disease can occur anywhere on the tree, even affecting the entire tree. Before treating your tree for diseases, you need to identify the root of the problem.

Causal Agents

Trees have no natural resistance to fungi such as Phytophthora, Verticicladiella, Ganoderma, etc. Fungi can cause many harmful effects, including wilting, root rot, cankers, slowed growth, and drooping. Take proper precautions by pruning and applying antifungal treatments to your trees.

Fungi tree disease occurs because of the honeydew created by sap-sucking insects. Trees infested with sucking insect colonies can develop black sooty mold. This disease can seriously weaken the tree’s structural integrity.

Dead Branches

To test your tree’s health, break off a branch and look for a green color on the inside. If you find a dead branch, examine the tree’s other branches and twigs. A dead branch or twig often indicates that the tree has a disease.
