Advanced Treatments: Systemic Trunk Injections

Don't lose your mature ash trees. We provide highly effective trunk injections (such as TreeAzin) to protect your ash canopy from this devastating pest.

Dutch Elm Disease rapidly wilts and kills mature elm trees by blocking water transport. We provide specialized preventative systemic fungicide injections to protect high-value elms from beetle transmission and fungal spread.

Feeds aggressively on the newly expanding needles of Balsam Fir and White, Red, and Black Spruce. As larvae feed, they spin dense silken webs that trap dead foliage, giving the upper canopy a scorched, reddish-brown appearance. Consecutive years of unchecked feeding lead to top dieback, structural vulnerability, and tree mortality. We provide targeted systemic trunk micro-injections directly into the conifer's sapwood to halt larval feeding and protect high-value landscape evergreens without the drift or environmental impact of aerial chemical spraying.

A notorious defoliator across Ontario, the invasive Spongy Moth (formerly known as Gypsy Moth) can strip mature hardwoods bare in early-to-mid summer. While healthy oaks, maples, birches, and poplars can often tolerate a single mild stripping, repeated defoliation rapidly drains a tree's stored energy reserves—leaving it vulnerable to lethal secondary attackers like the Two-Lined Chestnut Borer. We deliver targeted systemic trunk micro-injections directly into the vascular stream to halt caterpillar feeding and protect high-value shade trees without the chemical drift, mess, or non-target wildlife impact of aerial spraying.

Small but prolific sap-feeding insects, aphids target tender new foliage, twigs, and bark across a wide variety of deciduous hardwoods and ornamental shade trees. Using piercing-sucking mouthparts to drain vital phloem sap, heavy infestations cause stunted leaves, shoot distortion, and premature canopy dieback. As they feed, aphids excrete copious amounts of sticky, sugary waste known as honeydew, which rapidly coats leaves, vehicles, and patio furniture, giving rise to unsightly black sooty mold.

Microscopic arachnids that thrive during periods of heat, drought, and environmental stress, spider mites pose a serious threat to both coniferous evergreens (such as Spruce Spider Mites on dwarf Alberta spruce, white spruce, and cedars) and deciduous shade trees across Ontario. Using needle-like mouthparts to pierce individual plant cells and extract sap and chlorophyll, mite colonies cause widespread foliar "stippling," dull bronzing, and premature needle or leaf drop. As populations spike, dense sheets of fine silken webbing envelope branch tips and foliage. Standard broad-spectrum topical sprays frequently backfire by wiping out beneficial predatory insects, triggering explosive secondary mite outbreaks. We utilize targeted systemic vascular micro-injections to suppress active mite feeding directly through the tree's vascular system, restoring foliage vitality while preserving natural predatory balances.

Caused by microscopic nematodes that damage leaf tissue from the inside out, BLD can quickly compromise mature beech trees. We utilize targeted therapeutic root-flare injections and nutrient care to suppress nematode activity, strengthen natural defenses, and protect iconic beech canopies across Ontario.

The Agrilus genus represents some of the most destructive metallic wood-boring pests threatening Ontario’s urban forests, rural estates, and woodlots. While adult beetles feed harmlessly on outer foliage, their flat-headed larvae burrow deep beneath the bark into the vital cambium and phloem layers. By chewing winding, serpentine galleries through this vascular tissue, the larvae effectively girdle branches and trunks, cutting off the flow of water and nutrients.

Birch trees—especially ornamental white varieties—are highly vulnerable to canopy dieback from wood-boring larvae. We utilize systemic trunk injections delivered directly into the vascular stream to eliminate feeding larvae, protect high-value white birch, and restore canopy vitality without aerial spraying.

Oak trees suffering from drought, soil compaction, or storm damage are prime targets for wood-boring beetle larvae. We deliver targeted systemic trunk injections directly into the vascular stream to eliminate feeding larvae, stop canopy dieback, and protect mature red and white oaks across Ontario.
