Insects and Disease Management

New Image

Here at Susquehanna Tree Care we take a multipronged approach to dealing with insect and disease management. Often, but not always, these issues can be a sign of a larger health issue, and so getting a proper evaluation from a certified arborist is a great first step. They can help identify any immediate and long term issues and then come up with an appropriate plan to help re-mediate these problems.

Proper pruning can help to improve the overall health of a tree, and so it is both a great preventative action and also a good first step when dealing with many insect and disease issues. In some cases fertilization and/or pesticide/herbicide application may be necessary.

 

Emerald Ash Borer

The emerald ash borer (EAB) is an invasive insect from Asia that is responsible for killing millions of Ash trees across the US, and it has been in Pennsylvania since 2007. The EAB is a half-inch long metallic green beetle that feeds under the bark of trees and leaves a distinct D shaped exit hole in the bark. It is a particularly deadly pest and often kills a tree within three to four years of infestation. Common symptoms include upper crown dieback, epicormic branching, bark splits, bark flaking, and tissue damage resulting from woodpecker predation. Preventative care is a very necessary step to help avoid this deadly pest and an aggressive approach needs to be taken in the case of an actual infestation.

Susquehanna Tree Care is taking such action! This spring is the perfect time to have STC come inject your Ash Trees with a powerful pesticide that cuts the Emerald Ash Borer off at the source. Spring is a crucial time to get your injections to prevent any of the larva from hatching and further damaging your trees.  Even if your Ash Trees are not yet infected the injection will prevent any infestation from occurring. Book an appointment now to have an STC professional arborist come out and examine your Ash Trees!

Hemlock Woolly Adelgid

The hemlock woolly adelgid is an invasive insect from East Asia that feeds on the sap of hemlock and spruce. Here at Susquehanna Tree Care we see this pest on almost every hemlock we do work on. The most common way to identify an infestation is by what appears to be bits of cotton on the underside of the branches. It feeds on the sap on the end branches and causes the tree to lose it's needles and hinders new growth. Death typically occurs within four to ten years of infestation, and even trees and shrubs that survive are often weakened to the point that they die from secondary causes.
