2 young ash trees, emerald ash borer getting close replace them?
Comments (12)mdo, I can shed a little light on this: With the Emamectin Benzoate-style treatments available now, tradenamed Tree-age (The 'a' has the two little umlauts or whatever they're called above it, and the word is pronounced like the word triage), it is reasonable to expect two solid years of control from a single treatment, and quite possibly three years. For high-value trees like yours, this seems like a reasonable thing to do. Alternatively, the Imidacloprid insecticides will give a single year's control but are easier to apply. So even that's not a crazy thing to do. Environmentally speaking, either one of these methods is fairly low risk to surrounding organisms, being either injected straight into the trunk, or spread on the ground and soaked in via watering or rainfall, depending on which chemistry you reach for. The other half of your question I can answer too: What seems to happen with EAB is similar to other exotic insect invasions-there is a ramping up period, a period of overwhelming infestation, and then, just as you'd probably expect,a leveling off period after the insects have killed most of their hosts. So if you do happen to save yours during the hot time, you would still need to treat to have the surety of protecting the trees, but overall pressure would level off a great deal. These two lines of thought are straight out of very recent arborist's convention/seminars, so they are up to date. The relevance of this winter's cold temps was also a hot topic (Buh dum bum), but in reality, most thought is that while some of the less-deeply positioned larvae may indeed be killed, EAB has two larval forms and one of them is positioned deeper into the trunk, likely meaning the weather will have fairly little impact one way or the other. We can always hope though! +oM...See MoreEmerald Ash Borer Treatment Near Roses... OK or not?
Comments (4)The synthetic derivatives of pyrethrin, "pyrethroids", are not usually applied as soil drenches. The most common soil drench treatment for ash borers, and supposedly the most effective one, is imidacloprid (Merit). Merit is the insecticide in the Bayer All-In-One soil drench product for roses. Based on comments here, the All-In-One product doesn't help much with the japanese beetles, but it shouldn't hurt your roses. Hoovb's advice makes good sense.

Comments (10)The other problem with this tree is a rather large vertical crack starting from the ground and going right up. It's a frost crack - has been there for at least 2 years that I've noticed. From what I read, frost cracks on ash trees don't necessarily kill a tree but do give bugs an opportunity to crawl in there. After Rick's suggestion that it might be another borer, which I hadn't considered, I read about the Redheaded Ash Borer and the Banded Ash Clearwing Borer, native pests that attack ash trees. I'm quite certain there's something buggish in that tree, based on the woodpecker activity which is almost constant. I'm also thinking this tree is a goner - perhaps not from EAB but something else, slowly but surely. I'll still check it closely - I got some plants from southern Ontario a couple of years - is it possible for EAB to have travelled that way? Those plants are now planted right near that ash tree but that's got to be a stretch, no? Having to remove the tree will affect some plants that now benefit from the midday shade it provides (but they can be easily moved). Having to remove it will mean less ash seeds. Having to remove it give me the opportunity to plant something new there, and that's okay with me....See MoreEmerald Ash Borer
Comments (1)Everyone Please take Nate seriously. Parts of the Clinton/Brandywine MD area have been decimated by the Emerald Ash Borer. Last week the loggers took over 30 trees from my three acres. Monday an arborist will be coming to take three trees from my back yard, including a 26 inch diameter, 60 foot tall tree that shades my house. That tree appears perfectly helathy right now. But apart from the "all ash must go rule" my wife and I resigned ourselves to the fact that if they don't take it now and it gets the bug and starts to die, limbs could come crashing down on the house and/or cost us at least a thousand to remove. While we are in the "all ash must go" area, the state and the contractors are so busy, and the costs so high, that at the moment they are only taking trees here that are 1 inch in diameter and above. In the woods I have some 50 fingerlings that I'm afraid they will have to come back and take next year. To put this in perspective, this was not the original quarentined area. In the five years since the borer was discovered in the Clinton area the "remove all" radius has been expanded at least three times. This borer is prolific and nasty. As Nate says, don't move wood from quarentined areas. If any of you are in the Southern MD area and want more info contact me. Les...See Moretoronado_3800
