Questions asked by Tree Injection Summit participants…

Is there a system that does not require a hole to be drilled into the tree before inserting the delivery system like a hypodermic needle and syringe? And is the needle strong enough to just be pushed into the tree without too much force? Answer: ArborSystems’ Wedgle Direct-Inject Tree Injection System is highlighted in the Integrated Pest Management (IPM) of Midwest Landscapes manual as the only injection application method using a liquid injection that did not require a drilled hole. Our system uses a needle-like injection tip that is pushed through the bark. For more information our complete line of Quick-Connect Injection Tips for hardwoods, conifers and palms, click here.

“After two years treating 320 trees, we’ve lost only three.”

“Here in Michigan, Ash trees are dying everywhere. But there is a treatment that will work. We’ve been using a combination of Imidacloprid soil injections and trunk injections, plus fertilizers. In preventative situations we are saving trees. In fact our success rate is so high, our company has started guaranteeing trees. If we treat a healthy tree, we guarantee it to the next June, and if it dies we’ll refund the cost of the treatment. Our success has been astounding.

Let me give you an example. One of Michigan’s most exclusive malls is surrounded by hundreds of Ash trees. These trees were threatened by Emerald Ash Borers—we even found some exit holes. After two years treating 320 trees, we’ve lost only three. Dozens of median trees next to the mall have all died because the city didn’t treat them. Same thing down the road. One company had over 120 large Ash and they lost them all because they didn’t treat.

For the trunk injections, the only way I treat is with Pointer Insecticide and the Wedgle Direct-Inject System. With the Wedgle, I can make an injection in less than a minute, easy. If I have a group of 16- to 18-inch diameter trees together, I can average over 120 injections an hour. There is no way I can come even close to that with any other system.”

“I use the Wedgle to make money.”

“It’s very convenient and its fast. It just takes a little practice to get the technique right. You get the feel for when you’re in the right place—just between the bark and the heartwood. For anybody treating trees as a business, I’d recommend the Wedgle.

We primarily use Pointer Insecticide to control adelgids on hemlocks, and aphids and soft scale on mature trees. When treating for adelgids, we often spray and inject. But with spraying, the highest you can cover is about 50 feet, and not even that on windy days. With the Wedgle I’m getting right into the tree’s vascular system so I know I’m reaching the entire tree—all the way to the top. It’s effective and environmentally sound. Plus, the Wedgle requires a lot less equipment than spraying.”

Another Successful Fight Against Emerald Ash Borers

Susan M. Shock of Shock Brothers Tree Care, of Warren, Michigan, also shares success stories in fighting Emerald Ash Borers. Shock encourages her customers to have their Ash trees root-flare injected with Pointer Insecticide available from ArborSystems to effectively control cambium feeding borers.

“I have been delighted by the positive response of many of our customers who recognized the value in protecting their Ash trees and chose to disregard the helpless, negative attitude that was circulating throughout the news media and on the Internet,” Shock says. “Shock Brothers has completed its second year of protecting our customer’s Ash trees with Pointer, the Wedgle injection of Imidacloprid into the root flares. I am happy to say that we have not lost any Ash trees that started on the protection program in 2002 against the Emerald Ash Borer.”
