Tree Injections & Insect Protection

---

 Established trees bring shade, privacy and character to your property. When damaging insects threaten their health, early assessment and properly timed treatment can help preserve them for years to come.

Nugreen offers professional TreeAzin® trunk injections as part of our plant health care services, providing targeted treatment for susceptible trees affected by certain insect pests.

TreeAzin is a botanical insecticide containing azadirachtin, an active ingredient derived from neem seeds. Injected directly into the tree’s active sapwood, it moves through the tree’s vascular system to reach feeding insects.

The treatment interferes with insect development and feeding and can reduce reproduction, helping limit further damage.

Because the product is delivered directly into the tree, treatment does not require spraying the canopy—a practical option for trees in residential gardens, strata properties and commercial landscapes.

Depending on the tree species and registered use, TreeAzin can help manage pests such as:

• Bronze birch borer
• Emerald ash borer
• European elm scale
• Hemlock woolly adelgid
• Spongy moth
• Certain aphids

Our team assesses the tree and identifies the pest before recommending treatment. All applications follow the current Canadian product label.

Thinning foliage, dieback in the upper canopy and declining vigour can signal a problem. These symptoms can have several causes, so an accurate diagnosis is the first step.

Our certified arborists assess your tree’s condition, discuss whether injection is appropriate and recommend treatment timing and ongoing care. Results depend on the pest, the extent of existing damage and the tree’s overall health. Early intervention offers the best opportunity to protect a tree before decline becomes advanced.
