This is great news as long as you feel inclined to shell out 200$ per tree (rent-like) per (I think) 2 year period. This injection is sold through just one company and this seems curious. They stand to make a fortune with the exclusivity if claims are true. There is VERY little research on this chemical treatment, I believe off the top of my head is called Enemectin (sp?). Keep in mind, that if treatment is halted at any time in an infestation area, there is a 100 % chance at that time of infestation and death. There are no hopes for eradication in surrounding, untreated trees in other areas and woods. As populations build and ash are consumed and killed these huge masses of EAB will be lying in wait for any tree that passes a year of treatment just like an NFL football team sitting around a pizza box with just one piece remaining.

This also is not a viable choice for a town full (usually over 20% of all trees) of ash bcs of cost could easily go to tens of thousands of dollars to hundreds of thousands.

I have a shout in to my e mail friend PHD at the forefront of the EAB research about this news that just broke big on television last on 5 pm news. I plan to order this equipment if favorable reply. This chem has been chatted up for a year or so but environmental damage potential caused it to fade from the limelight. Looks like the manufacturer just struck up this deal at the last second with this company to use it's injection system that will keep it safely contained as a systemic.

I might also that claims of 100% guarantee of success that are being barked by many regarding treatment is said to just mean that if tree dies then they will refund the cost of the treatment.

Research is so thin on this new topic that, for example, a huge bustling office at the EAB Hq. has turned into just one person in there answering the phone.
Lack of success, huge expenditures, and a boggling future are some reasons.

The researcher I speak with said our state is projected to be covered with infestation in approximately 15 years or less.

Spend or replace......the only 2 options.

I worked for the owner and inventor of arborjet and we used with great success on Hemlock woolly adelgid. Not familiar with the chemical they are using for EAB but I know that the trials are extensive before they can be put through the arborjet. All in all in my opinion it is the best and least invasive systemic injection on the market. I understand your reservations TV though it seems steep the cost of application. Is that the cost of chemicals to the applicator or the client??

bigshea13

burn em out. sucks right now but good for future generations.
they need to mate to lay eggs. they mate after and as they feed on the foliage. do you think the ash could withstand 1season without leaves....just to keep the eab from moving in?why stay if theres no food. if they stay the tree dies. without its foliage for one season at least it stands a chance....right? or wrong? ive seen tent catipillar epidemics where they clean the entire forest of foliage for the entire summer and the trees survived for the most part. im not talking about a few crawlies. there were so many the roads were slick and you couldnt go in the woods because it was like a giant cobb web.

treevet

It is the cost to the client. It likely will go down when newness wears out. It is just the utter lack of hope of eradication and the massive amount of "host bodies" to perpetuate the infestation. I can see the key tree in the landscape deserving of this investment or the client that has no worries whatsoever with spending, but when a client (which means, I think, you as a service help in the best investment of their dollars) it is often best to eliminate the source and start anew.

As for "city work" city trees, that is a no brainer, start over with a ( ) year plan.

treevet

The foliar feeding is a non issue. The damage is done as larvae feed on the cambium (predominantly the xylem) and the tree starves to death. They have to be treated with a systemic.

This is by no means a "NEW" product, but perhaps they have discovered a NEW use for it.

Here is the link to the site that we use in Canada: Search Product Label

There appears to be a lot of well kept secrets in the chemical game, and what can be used on trees here is the best kept one.

Treelore

why do these registration labels not mention emamectin is that a new name for an old product??

TreeDimensional

Treelore, thats a GREAT question. I was hoping that some of the other members here knew the site for their countries. It is always best to compare apples to apples.

I searched using emametin benzoate, and found absolutely NOTHING! Does OZ or the Uk have on-line product searches. I bet they do, I am reluctant to waste much time on trying to find out for my area. The public is funny, some people want to spray everything, and the other half won't let you near their place IF you've been near a closed chemical jug.

This is often an issue for conducting business. The cost of insurance keeps me out of the spraying game. The other thing is that the information and the actual products are near to impossible to get. Historically, Canada is behind the eight ball when it come to timely decisions on chemicals. You would think we would be at the forefront in Herbicides and pesticides, but the UK is where most of the research is happening.

treevet

Emamectin is not Carbaryl/Sevin. Don't know why you came up with this product when searching but maybe this product name reg. expired or maybe it is because the current product name has a little mark above the a (in age) that may denote the flat a in computer key speak. This would make it sound like triage as I mentioned. Whatever, they are not the same product.

I don't like to speak prior to knowing what I am talking about but I will take an educated guess in this case. $ have been pushing mfctrs. to get this chemical out to the public to control EAB. Big $ s. They have been unsuccessful because of validated potential damage to the environment (with EmBen). It is right near timing (beginning of May) to get any control with the hit on the first instar.
The connection was maybe put out for bid to companies capable of delivering this chem with an injection (safer) and Arborjet got it. This appeared on our newscast on Thur, 4/17/08 I believe. Everything is so new you won't find much on the web. I think this product was granted (Tree-age) an emergency registration.

As I said this an educated guess. Probably next to no history with this product/delivery. I believe Grosse Point Farms, Mich. is having success with injections on EAB with Arborjet, but I think it is with Immidacloprid (sp?)

treevet

PS. As Ekka would say and it is true at times this (TW) is a form of the "News".

treevet

Here s a little more news for those inclined. Hope I copy this right.

Emamectin Benzoate

treeseer

If it only costs $100/year to retain a $5-10,000 asset, you don't have to be Bill Gates to afford that.

Even for towns, it would be worth it for landmark trees.

treevet

Agreed, but as I did with Pentrabark, I will return with some opinions from my Email friend, a front lines researcher on EAB at Ohio State University. Any claims you have seen on the news or read in the paper so far are likely manufacturer's and may be "Sales puffs" which are not illegal as proven in car sales.

This whole set up (EmBen/Injection) is hot of the press. I sap suck ocassionally on TB and they don't have shit on it.

Cool Great info you always come up with up Ekka. Seems like their could be a small issue with birds feeding on caterpillars that feed on the leaves by our birders. But why are we not concerned about the health of our damn native caterpillars?

I may have some more info to provide in the future.

As I mentioned earlier, I received an e mail giving more empirical information regarding EB injections I requested, from one of only 4 who have tested it on EAB.

"Tree-age is looking good in MSU studies, only they have thus far reported only one year of data. We are also studying it (at Ohio State U.) and have found in two trials we achieved 94% and 74% reduction in successful EAB colonization. These results put it on par with the best results achieved with imidacloprid."

This says to me that it is testing well but on an equal basis with injectable Imidacloprid. Seems this one is not the holy savior they make it out to be but it is at the top of the food chain and great to have another tool. This is true especially if resistance is developed to one of these products you may use or if one becomes/is outrageously expensive.

Tree Machine

Imadacloroprid can be administered by root drench (advantage being low-tech ease of application), whereas enamectin requires the pressurized syringe. Minimally invasive intercambial injection (contrast with drilling holes for trunk ampules) is preferable to root drench as uptake is complete and quick, compared to uptake by the tree's root system. And 2 years is far better than one.We the Arborist will put the price on the service A thigh-diameter tree will be faster to treat and use less emamectin than a two-hugger giant. We will look at our costs, look at the tree and come up with a price for the client. $200 quoted in the press seems high, but from our standpoint, that's a far better price than a low-ball.

Emamectin is manufactuured by Merck and went to market in 1997. Emamectin's 'environmental danger' isn't to the 'environment' so much as to other insects that would feed on the leaves of treated trees. It is toxic to bees. There is also concern for butterflys, moths and other lepidoptera. Seemingly, enamectin would protect from the gypsy moth also, that fuzzy bastard that has wiped out so many millions of oaks in the northern US, especially my home state of Michigan.

Here the chemical skinny on Emamectin benzoate. This is a very informative page.

Tree Machine

Here's imidacloprid.

treevet

It is "Emamectin Benzoate". Probably either injection, this or Imidacloprid is preferable to soil drench for translocation. According to research there is no proof as yet of efficacy of residual into next season and there is little proof of control of very large ash. Manufacturers will claim otherwise ofcourse though. I am in e mail contact with the author of the Emerald Ash Borer fact sheet from Ohio State. They are probably waiting for the bloom of Black Locust that signals the emergence of EAB and then their life becomes Hell again.

Have you got EAB in Indy? Gypsy Moth? I went through Gypsy Moth in early 70's in NJ and we were spraying houses because the entire house and windows were covered with caterpillars. They are talking about it around Cincy again but I have never seen one tan egg mass on underside of branch and they are very easily spotted.

Tree Machine

My Grandfather lived in northern Michigan, and I watched a large swath of the Manistee National Forest lose insane numbers of oaks. I would visit the forest with him every Spring for Morels and steelhead season, and again in the Fall for salmon season.

I saw the forest before the infestation, during the infestation and after. It was heartbreaking, but the bringing in Grampa's firewood the last few years of his life was easy pickins, forests full of standing and fallen dead oak. I remember one time when the gypsy moths were feeding so heavily you could stand quietly in the woods and the sound of their poop falling to the forest floor sounded like a light rain.

The beetle has been positively identified in the two counties north of me. My county (Marion county) is under quarantine.

At the Indiana ISA conference a year and a a couple months ago I attended the EAB presentation by Dr. David Smitley of Michigan State University.After the talk I stayed after to shake hands. I told him the bug was in the adjacent counties to the north of me. He told me to get prepared, and make the infestation part of my reality. If it's not yet in my neighborhoods, it will be.

Not familiar w the mushrooms, but that is a damn nice looking fish and looks like you and your Grampa had a great day.

I know what you mean by raining poop hitting the leaves. The first year we hit them with Sevin, they fell immediately. The second year they fell after we got to the end of a long driveway. 3rd year it took couple of hours and the next year it hardly worked at all. Guys were using stuff that made birds fall in the yard. Few years later they disappeared as a fungus attacked their bodies and killed them. They have reappeared out there I ve heard and I saw stands on the PA Turnpike dead couple of summers ago I assumed they killed.

We ve got to worry about resistance to treatments from these also. They are harder to hit as they are inside tree. If you haven t seen one you should visit a infestation site. You will be amazed the devastation these little bastards can cause. It is hugely impressive.

treevet

I am familiar with Smitley. The guy I am in contact with is Dan Herms. What a great guy and very acessable and not at all condescending like you might expect. I think their are 4 lead researchers (I could be wrong) and these are 2 of them, the other being Deb McCullough (sp?) and not sure of other. The first seminar I attended was in 2002 with Ind Arb Assoc at Purdue Univ for EAB.

Looks like you are in one little hot spot or it is called a brush fire I think (as opposed to a forest fire). IMO when you are in a quarantined county and no contiguous quar counties around you then it spreads much faster as all wood and other refuse has to be distributed in your perimeter and it doesn t matter to anyone if it contains eab larvae. Reality is sad sometimes.

I just went in and passed a 2 hour test for a pesticide license last week. Have you done it? Could stand to make some good money and IMO it is very ethical if person wants to spend it and can afford it. I sold my big 50 gpm sprayer a few years ago but as luck would have I have a small one if I get into soil injection.

Tree Machine

That was early.

I attended the 2006 teleconference, here at a local Purdue extension office. I shot the slides with my still camera as they were shown, and brought them back.

I was relieved when none were found in my neighborhoods last year (though that doesn't mean they're not here). This year I have a feeling the tide will change.

They emerald ash borer is high on my radar. I do not look forward to their arrival, but in the meantime I inspect every single ash tree I climb, prune or take down, and regularly visit Michigan State's EAB site,
the Michigan State Invasive Species Initiative,
Purdue University's EAB site
and the Indiana Department of Natural Resources EAB site.
http://www.google.com/search?site=emerald%2Bash%2Bborer&hl=en&q=emerald%2Bash%2Bborer&btnG=Search searches now and then to find stuff not contained in the University links.

I keep informed through these venues and when it is time, I will buy the injection gun, chemicals and begin treating ash trees in my area.

I sincerely do not look forward to that time.

treevet

Me either. We re still clean in my town as far as anyone knows. I am buying the gun but also may do some soil injections for those who want many treated or cannot afford the root flare injections.
