Hope this is the right forum - have to large ash trees that I would hate to loose to that bore beetle that is plaguing New York. I was quoted over $700 to inoculate my two and I just and justify $700 every two years.

Is there any do it yourself remedies?

They have been previously inoculated by the previous owner to this house
 
How big is the tree? Tree-age is definitely more effective on larger trees.

Is there any indication of dieback in the tree now? If so, again, Tree-age is the best bet to get it through the initial wave.

If you are ahead of heavy infestation, a generic imidacloprid soil drench is effective if you apply it correctly (right around the base of the tree, into the soil, be close any mulch or turf). I like the 2F formulation. Use .2 oz per inch of diameter of the tree is under 15" dbh or .4 oz per inch if it is over 15".
 
Like ATH said, what is the diameter of the trees 4' from the ground. Knowing that we can tell you if you are getting a reasonable treatment price.
 
Morning !

Sorry for the delayed reply. The two trees are 79" and 83" in circumference @ 4' from the ground. Additionally I wanted to share these pics from the previous home owner having them inoculated.

The trees were due in June and I just can't justify hundreds of dollars every 2 years .

Both trees at this point are quite healthy20180813_202142.jpg 20180813_202153.jpg
 
Depends on how much delaying the inevitable is worth to you?

That was kinda the way I look at it. I mean if it was $100 - no issue. But $700 give it take every 2 years with no guarantee I just can't justify. I would hate to lose them but.....
 
It's a losing battle considering at the end you'll still have the removal cost to add on top of the chemical maintenance cost.

There is no cure cure for an EAB infested ash I'm aware of, just a chemical means of slowing it down a bit.

Viewed from a strict money saving angle, cutting them down while still green and relatively safe to climb tops the list.

What's the longest any of you blokes have kept an EAB infested ash alive chemically?

11 years and going strong IF they've kept up treatment.

I had treated at one property from 2008 to 2012. New owner didn't treat. Got back out this year with current owner and they are in decent shape...maybe 20% dead. If those had gone untreated the first 5 years they would have been toast - nine lives through that. There are almost no untreated ash left, so I think the pressure has been much less with lower big population. I am very confident that an appropriate treatment program will keep EAB at bay as long as it is followed. I was initially very doubtful...but have seen otherwise. Early treatment is the key.

To the OP:
If they are just using Tree-age alone at the recommended rate of 5ml/inch, that is a little high, but not bad. If they are using 10ml per inch (which is probably appropriate for just a few years when the initial wave is hitting the area really hard) then $13-14 is probably close to market price. I have done soil treatment (imidacloprid) every year and Tree-age plus soil applied imidacloprid every other year. I was a little over that for the combined using 10ml per inch...but have come below that now using 5ml per inch.

If you don't see any dieback, you can successfully treat with soil applied imidacloprid using .4 oz per inch of the 2F formulation. I have some going on 11 years that still look good...I was recommending stronger treatment when we started, but they didn't want to spend the $$, so chose imidacloprid and it has worked well.
 
Forgive my extreme ignorance but the soil treatment? How is it applied, where do I get it, how much is it? I'm very new to this hobby
 
Where in NY? You should get some more quotes as that seems a bit high. It matters in terms of pest pressure or infestation level. Homeowner treatments will not be effective in western NY due to large number of bugs present which are rapidly overwhelming remaining untreated ash trees. Same probably true for most of Finger Lakes region and CNY. After the killing wave runs through you may be able to drop down to homeowner treatments, extend treatment interval or reduce dosage.

Soil treatment is insecticide applied around base of the tree. You should read up @ http://emeraldashborer.info/files/multistate_EAB_Insecticide_Fact_Sheet.pdf
