Interesting. Not sure then if it’s not from second flush or treatment. It’s possible id imagine disease severity can ebb and flow depending on the trees reserves and ability to fend off disease pressure. Maybe there is a factor environmentally that effects viability of nematodes like last years...
5mL upped to 10mL for trees over 35”. Dino has a super short residual so definitely get them off that program, not appropriate for EAB. I would only recommend the bark treatment if injections are on the late side for quicker protection until the EB moves up into the tree.
I wonder if the ebb and flow some are noticing is related to beech aborting severely affected leaves and putting out the second flush which is fairly common in the advanced stage. And I wonder further if that second flush temporarily decreases the nematode populations as a result.
When it was bad in the NE from the Canada fires we either had shortened days or shut the offices for production all together. One of the days I was with a trainee and the sky was orange and hazy. Pretty incredible it travels so far, but clients were appalled we were working in it. It may not...
I have a bottle of sight line (triclypor) and Clearcast (imazamox). My herbicide knowledge is really not up to snuff despite doing a lot of invasive management for a few years (mostly cut stump with glyphosate formulations). Will either of these be decent post emergent treatments, with some...
I’m laughing because I didn’t even realize I was responding to one of my own threads before.
I learned that Florel is tricky due to the fact not only is it done at time of flowering, but flowers obviously open at varying times requiring multiple well timed treatments and you must make the...
We don’t do it and don’t see the need. The bleeding from injection sites we often see is more bacterial or more along the lines of bleeding similar to pruning certain species in the spring. I’m pretty sure we have sampled the bleeding and confirmed it’s not Phytophthora. I prefer to, and train...
A few interesting ones from over the years.
These old weeping cherries always have very interesting root flares. Two of these in my new neighborhood and very incredible trees. Would love to figure out the cultivar. They don’t seem to be grafted?
