Fwiw first day in past few, no new fireblight strikes. All i changed was watering lawn. Could be totally coincidence though
I have been breaking off the apple spur in most cases.
Just a reminder for folks to read through the condensed IPM guides. A lot of the common questions are covered. Page 19 of this Cornell one covers fire blight - what it looks like, what and when to spray, seasonal tasks, etc.

Not fire blight, no - though I don’t know what it really is either. Several of my young trees have this, too.

One of my serviceberries/juneberries looks like this, I understand that they can get fire blight. What do you think?
No no ooze or blackened veins.

Another fireblight question
This is Akane grafted to mm111 last spring. It didn’t grow as well as some of the other grafts but seemed healthy. Did not bloom as far as I know. The first strike was near the tip, this one is 12-15” from the ground, above this the leaves look normal. Should I cut all the way to the rootstock, leave a couple of inches of interstem/akane, or just trash the whole thing?
The trees I thought would be susceptible have escaped so far while the trees I thought might be OK are getting hit.

I can’t quite tell - are the strikes on both sides of the stem?
There are two areas, the upper, just below the green tape the trunk is dark and stems on both sides are affected. The lower area of darkened trunk just has the scaffold on the right affected.
I cut the trunk about 3” above the graft, only about 6-7” below the lesion, the cut looked clean. If it shows any additional sign I will cut back to rootstock. If it survives I will probably regraft to another variety next spring. I grafted two Akane last spring and the other has shown no FB so far.

How do you all dispose of infected material? I’m often under a burn ban due to wildfire danger but I don’t want to just pile that stuff up in my yard, and taking it to the dump seems like a lot of work plus contaminating my trailer…

I stick dead wood in burn barrel (55 gallon steel.oil drum) and throw a little ash and coal over them until it’s safe to burn in the barrel.

Spent some time pruning out FB on apples. Man I need to get serious about a spray program for apples next year!

knock on wood my apples are almost totally unaffected even though I have horrible trouble with pears. I’m definitely starting to wonder if the strain in my neighborhood is more for pears.
I do spray though. Which is a huge pain in the neck.

I finally found a apple spray schedule from Illinois Extension. I had a quick read through, need to study… looks like they are saying at silver tip copper for FB. IDK what do you make of it?
I use the weather degree hours/day model. After the flowers open, you accumulate degree hours. If it’s going to rain or be really humid you spray if the accumulation is enough. In my area it takes only one day most of the time to accumulate enough hours for there to be high risk - so I end up spraying every 3-5 days. Which is annoying.
I’m spraying different trees (those with open blooms) and I switch from pears to apples, so i’m not spraying every tree every 3-5 days, but it makes for a long month.
Fertilome Fire Blight Spray. Streptomycin Sulfate (22.4%)?
Sounds like you got it figured out with your sprays.
