Disadvantages of Tree Spraying

Spraying large trees with hundreds of gallons of pesticide exposes you, your family, pets and possibly your neighbors to toxins while killing beneficial insects. Even with the best timed spray applications, many of today's most destructive insects and diseases cannot be controlled.

Trunk Injection Advantage

Trunk or micro injecton is the most effective alternative to spraying or applying pesticides to the soil for tree insect or disease control. With Trunk or micro injecton, small amounts of pesticide are injected directly into the tree. The water soluble pesticides are carried through out the tree's vascular system putting the pesticide in direct contact with the pest.

Environmentally Friendly

Additional benefits are no exposure to people or the environment, greater effectiveness and relatively minute amounts of pesticide. According to studies there is no adverse effect on the tree to the injection process, (see the link of a study below)."

Cost Effective

Equipment & formulation costs  are much less costly than they use to be. We can offer a program that is valuable to the homeowner and still very cost effective. 

Trunk Injection Facts

Healthy trees successfully compartmentalized injection wounds without any signs of infection, decay, or structural damage. The vascular growth rates for healthy trees during a two-year period following trunk injections were similar to or greater than the growth rates before trunk injections. Tree growth after injection resulted in the rapid closure of wounds without any detectable adverse affects on tree health or structure. [Arboriculture & Urban Forestry 2011. 37(1): 6–12]

Destructive Pests of New Jersey

Asian Longhorned Beetle

The Asian Longhorned Beetle is a destructive pest of trees, originally from China. It can be identified by alternating white bands on long brown/black antenna. The appearance of small holes on trees can be an indication of infestation. If you see this pest please contact the New Jersey agricultural Extension Service at the link above.

Dutch Elm Disease

Dutch Elm Disease is a fungus which affects the American Elm. Symptoms begin as wilting of the leaves which turn yellow, and eventuelly brown. Dutch Elm Disease is a result of the fungus infecting and clogging the vascular system (Pholem) of the tree. This prevents water movement to the crown causing the browning and yellowing of the leaves, as the tree wilts and dies. The disease is spread by the Elm Bark Beetle. Certain fungicides, when properly injected, are effective in protecting elm trees from infection, and must be repeated every one to three seasons. Elm trees should not be pruned during the growing season because sap oozing from wounds may attract the Elm Bark Beetle.

Bacterial Leaf Scorch

Bacterial Leaf Scorch is an incurable plant disease that has infected an estimated 39 percent of oaks statewide. There is no cure for Bacterial Leaf Scorch, but with proper management affected trees can often be maintained for many years.Infected trees will need to be pruned, to remove infected limbs, and in many cases may need to be removed.

Emerald Ash Borer

The larval stage of the Emerald Ash Borer bores holes into the trunk and serpentine feeding galleries which disrupt the flow of nutrients as they rise up the trunk from the roots to the crown via the phloem (the tree's vascular structures) just under the bark, which eventually results in the death of the tree.

Hemlock Wooley-Adelgid

Adelgids are small insects, related to aphids. The hemlock woolly adelgid sucks sap from the young branches which results in needle drop and branch dieback.

Birch Leafminer

Birch Leafminer is an invasive wasp which lays its eggs into the leaves. Once hatched, leafminer larvae consume the tissues between upper and lower leaf surfaces causing brown blotches.” Healthy trees can withstand occasional attacks by birch leafminer. Repeated attacks can result in the general decline and death of the tree over time by secondary pests such as fungi and the bronze birch borer.

Pine Bark Beetles

There are many species of bark beetles that infest conifers. Adults tunnel through the bark, mate and lay eggs in the phloem, under the bark,where the larvae develop. Adults develop from pupae and emerge by boring out through the bark. Multiple generations a year are possible.

Leaf Chewing Caterpillars

Caterpillars are the larval stage of moths and are among the most serious defoliators of trees. The eastern tent caterpillar is responsible for defoliating forest trees, as well as cherry, apple and other ornamental shade trees. Others include the gypsy moth, winter moth, spring and fall cankerworm, bagworm, clear wing borers, pine tip moth and tussock moth. Some moth larvae, such as tip moths and clear wing borers, feed inside the twigs, shoots or trunk of the tree and are virtually unseen.
