next spring im going to add those fungicides to my dormant oil / copper spray. i lost all my crop of cherries to blossom end blight this year despite spraying copper early/ late and spraying with immunox and infuse. it also got bad enough to kill one of my cherries.
Thank you so much, Scott.
Now, on to pears, mine have gotten pear psylla damage so badly. At first I thought it’s fire blight. Then, when I looked closer, I believe it’s psylla damage. Do you think it’s psylla?
Some varieties got it worse than others.
My guess it’s blister mites.
Quite sure it is not pear leave blister mites. I am familiar with PLBM damage.

More bad news. My Freckle Face nectarine on Nemaguard has had cracks here and there along main branch for the past few years. I believe those cracks areq weather-related (cold and warm spell swings).
Once there are cracks, canker has moved in. Nameguard is also susceptible to canker. It’s not bacterial canker. This is perennial canker, a fungal disease that is deadly to stone fruit. I have seen inner branches of this tree are dead and dying. Every one of fruit on those branches developed brown rot.
Not sure if canker would spread to the whole tree and kill it this year. If it would, I’ll lose 100’s of fruit.
Tippy, are you doing scouting walks a few times a week? You have many fruits that reached extreme level of rotting, and that release millions of spores greatly endangering other fruits/trees. I usually find rotting fruit much earlier than that, and immediately remove them.
My Honey Kist and Snow Queen trees developed severe bark cracks too, with the former showing profuse canker, but no fruit is rotting like yours.

I’ve used organza bags (mostly dark colors) to bag fruit. (they don’t work fully but they help including fooling birds and protecting against wasps). I bagged them about 10 days ago and pretty much thought they were all set.
Those dying limbs were high up on the tree. I did not noticed them until yesterday. Once I got up the ladder to look closely, I realized the extent of the damage (several dying limbs and mummified fruit).
