Thank you Steve.
I researched your answer and it 100% is an exact match to my problem.
Year 1 I had amazing plum fruit
Year 2 (last year) it got these markson the fruit and all the plums fell off the tree way before I could harvest anything.
Year 3 this year. I see it happening all over again. Thanks so much for this information.
I will rush out tomorrow and find some kind of solution to spray like clay to try and save this years crop!
Again, thanks so much Steve!
