Insecticide treatments will depend on the tree and diagnosis.
Typical treatment methods include:
- Targeted or preventative foliage sprays. This is for any insects that may be affecting the leaves of the tree which will decrease vigor.
- Preventative trunk spray. Insecticide is applied to the trunk and major limbs to prevent an insect from boring into the tree in the future.
- Targeted or preventative trunk spray. A systemic insecticide is applied which the tree will take up to help target borers and other insects that may already be in the tree.
