    Are any of you thinking of treating for Ash Borer?

    We are going to start getting attacked (if not already) and I have several customers that want to protect their trees, but I am far from a tree expert.

    What are you going to use?

    When do you start?

    I have not had time to look up any info yet...but wanted to ask you guys.

    Tree Monkey,

    Can you help me out here?

    Thanks,
    RC

    Before I got into the industry, I talked w/ an acquaintance that said you could do it, but once they're there - not much you can do.

    Your easiest decision will be if you prefer Stihl or Husqvarna.


    It's a very grave situation here in the midwest regarding the emerald ash borer. Not only is it sad to see street trees dying, but going into the forest and seeing 24" dbh sawtimber trees rotting in the woods is traumatic to witness. It doesn't hurt until it's "in your own backyard".

    Paperwork/methodology is being pushed through to introduce a natural (imported) predator, but who knows how, or if, that will work.

    Tons of info on the web. Here is one article that walks you through the annual care cycle to attempt to save individual yard trees:

    listed in that site is the regional "hotline": http://www.emeraldashborer.info/ The map shows it is well into Ohio.


    Some professionals have set up businesses around the emerald ash borer such as this:

    I don't know about the economics of treating individual trees.

    I've been reading about good results with Merit injections, and Moget has some capsules that are supposed to do a number on it. It is treatable.

    check on a chemical named onyx. It's just a high concentrate of bifenthrin but i believe some borers are on the label. You should be able to find it on the internet. Good luck. Make sure your license warrants tree and shrub! different here in va.

    There is a newer surfactant called Pentra Bark that penetrates tree bark. You can spray insecticide & Pentra Bark in a basal bark application on bark from base to 5-6' & it penetrates into the phelloderm. It then translocates into tree. You can use imidicloprid (merit), but studies have shown control to be less than desirable. The most promising chemical I have seen is Safari.

    Rows & rows of street planted Ash trees......$$$$$$$$$$

    LL,

    Pentra-Bark only works well with a small number of materials, even at extremely high application rates. If it's proven to work with Safari then go for it but I wouldn't get my hopes up for other things to work with it from the dismal results I've seen.

    PHS, That's good to know... I have been one of the first in our area to use pentra bark. Most of what I have used it on it seemed to work OK, but I'd hate to risk someone's prized Ash in thier ft. yard if it is at all "iffy"!

    I sprayed a Linden w/ pentra bark & imidacloprid that always is defoiliated by Jap. Beetles, and it showed minimal damage this season.
