Best tree injection system

Eric Frei

What would you say was the best tree injection system and why.

Here's some: this one boasts no drilling! ArborSystems - Hardwoods

Or the sidewinder system made in Australia tree injectors and injection technology

Arborjet Arborjet?s Tree I.V. Micro-Infusion Tree Injection, Tree Care Equipment

There's others to add, like the simple spring loaded syringe types ... what do you use?

I've been using ArborJet's QuickJet system.

I like it, the plugs are good.

Havent tried the others, so cant say its "the best" but very happy with it.

I assume that all of you guys are aware that imidacloprid is toxic to bees even when ingested by the bees through pollen from the trees you treat with it. The same is true of the new movento systemic insecticides.

It is the primary suspect in colony collapse disorder, and has been banned for use in insect control in germany.

I just thought you environmental stewards should know this before contributing to the demise of your honeybees in your areas of the world.

I like the look of the sidewinder

I think to the layman it's quite obvious that when a chemical kills a pest then in higher dosages it can kill more or larger pests.

In tests they're feeding daily to various animals high dosages based on the mg/Kg weight of the animal. I'd say you'd have to be an idiot to assume eating the crap in high dosages would not harm you, but we all know eating McDonalds in high dosages will also kill you.

What the studies fail to find or prove is at what dosages and after what period of time it takes effect on bees for instance.

So you treat a tree, how long before that tree is "safe" for bees?

Then implement a scheme where treatment can only occur after flowering or at least 6 months before, you simply dont treat tree at a time when flowering is happening.

Doesn't matter what chemical you use, it will always have a negative impact somewhere along the line.

IN the case of elms, injection is done in full leaf & after flowering, so risk should be low.

In fact, that could be another good point towards trunk vs soil injection for that application.

Soil injection is done earlier on, so may be present in the tree at the time of flowering.

Although if the product has residual effect for 2-3 years, then that would be negated in the following season anyway....

Just thinking out loud here

ive been doing alot of looking into this as of the last month or so, do to the discovery of EAB in our area, ive been talking to alot of americans about the system because they have been dealing with the pest for a longer amount of time, they all recomend the wedgle system, drilling trees comprises about 5 % of the vascular cambium which isnt a big deal if its healthy but when your dealing with seriously declined trees its much more of an issue not haveing to drill into the sap wood means its on less thing the tree has to worry about and compartmentalize in a time where its barely hanging on

the only issue with this is that the Canadian gov is so pro green that they wont let us use anything that is confirmed to work on EAB, they just approved Tree azin which is about 50 % effective, and it only has an emergency licence which expires in august,

40% of Toronto's urban forest is White and Green Ash and within 5 years if nothing is done there wont be a single one left

sorry a little off topic, we are also using the wedgle system to treat for chlorosis in Acer rubrum and Quercus palustris, the only downfall for this system is that all your chemicals, and fertilizers need to be in the special bottles, but the guys at arborsystems are more then happy to bottle anything you send them, at a fee.

if anyone has any information on EAB and what chems i can use in southern ontario send me a pm it would be greatly appreciated

its all about weighing whether that negative impact is better then the negative impact that your trying to fight, the lesser of two evils if you will

tree injection systems are by far the way to go, it uses much less chemical and it contains it in the tree apose to root dredging, which i dont have alot of experience with but im going to say it uses alot more. as fore mentioned im trying to use it to fight EAB and the applications rate is 1 ml per at 4 inch intervals around the root flare of the tree

Injecting a "seriously declined tree" for EAB is a losing proposition. Chem will not translocate adequately and failure is almost guaranteed.

I have been using the Mauget system since it was invented. I have been satisfied with results enough to keep using it for all my needs. I used Safari with Pentrabark (EAB) for 2 years when it was all the rage but since have gone to Immidacloprid in the Mauget system since it tested at the top of the chart along with Treeage.

Great food for thought here, down my way everyone sprays blackberry in flower with anything and everything to aid the take up of the poison.

Doesn't sound so good to me anymore..

I have a sidewinder, (backpack version) for elms mainly, unfortunatly finding correct dosage is not easy, im sure you have found lots of tests from the US, i have heard of ppl using very low concentrations of confidor. i know also ppl using ivermec "cattle drench" at least i think it was ivermec it may have been eprinex but it was drench.

Google Ivermectin; abamectin with "elm leaf beetle" and you will find info about it.

large tree's perhaps but younger trees injected (12") with imidiclomprid and a 0-15-10 fert stand a very good chance

Arborjet using Arborplugs injection site only 5 months after treatment on small Golden Elm. Free of Beetle damage other than few shot holes from original ingestion, no subsequent skeletonization.
