I figured the third was rust, but can't figure out the other two. The trees are new, so we didn't get any apples to check for scab. I don't think that's it though. I'm surprised to see any diseases because I followed advice on here and did a recommended spray schedule with captan since right after dormancy. Any ideas on the other two pics? Is there a better fungicide to use?

They both look like plums of some sort, they are not sweet or sour cherries. Lets go through some of the problems. The little black bugs and yellow eggs are ladybug larvae and eggs. Those are the "good guys" eating the aphids, don't pull them off. The dead looking branches are probably due to brown rot blossom blight. It will feel slippery when wet if its brbb. The holes in the leaves are some form of shot hole. The galls are probably from some kind of mite. Its hard to tell what the long-term chances of the trees are but they need to get on a spray program if you want to keep them. Read up on these diseases/pests and their treatment, ask more questions if you have them! Scott

I have exactly the same tree from the same source. Of all my apple trees it seems the most disease prone. It's the only tree that I didn't pay much attention to disease resistance when I selected it. Alot of brown spots but it seems to carry on. It is having its first couple of apples this year and if the have much scab then the tree is coming out. I knew I was taking a gamble when I planted it. There may come a time to cut my losses, but not yet.

Possibly scab? Or water stress? IF in container, it doesn't take much wind to have them dry out and have the leaves scorch. If the roots are white and the cambium is green, they should leaf out fine next year. I would plant them and take the chance. The price was right.
