Fruit tree disease
Hi, I'm starting to experience a disease on two of my fruit trees in my back yard. I noticed this a couple weeks ago, sprayed them once with an all purpose bug/disease fruit tree spray and my sprayer broke. I've been away from home but I did pick up another sprayer and spray them again today and need some help to identify the disease to ensure I'm taking the right steps.
Last fall I did trim the trees for the first time ever. I'm worried I may have not done this properly and caused the disease to start. So far the disease is limited to 5% of the tree.
I believe these are my apple trees... lol... not 100% sure and definitely couldn't tell you exact genus/species of the tree but they are maybe 10 years old or less.
