For a couple years I've been using an imidicloroprid soil drench to treat or pre-treat my two Fraxinus americana for EAB. From what I read the tree-age or arbor jet system of trunk injections is better. I've seen some videos and it seems like something I can do myself. However I'm not finding a "kit" or whatever online. Google and I haven't been thinking alike lately though. If it makes a difference one is only ~14 inches in circumference dbh. The other is something ridiculous, I forget what I measured but mama ash is big. This house I'm in the St Louis area and since I removed three other big white ash because of structural failings and proximity to the house I'm probably a bit over sentimental on these. I'm sure there is a post on here or a good link and advice from one of you all and I thank you in advance for pointing out something that is probably obvious.
