Title: Odd disease/pest/fungus on fruit tree
Post by: Viking Guy on April 07, 2015, 01:57:47 PM
Ok, I have an Anna Apple that has been covered this year in tiny orange-red dots from the rootstock to the highest twig.

I've never seen this.  Looks like some tiny version of rust, but not rust.

Some of the branches are dying back.  It flowered heavier this year than I've ever seen, and dropped 100% of its fruit.

I think it is toast, but need to know if this is contagious and if I should quickly dispose of it?

By the way, black two-stabbed lady beetles (Chilocorus) have been feeding on the orange dots.

Thanks.

I thought that at first also, but it's not.

The dots are uniformly spread on 100% of the tree bark and much smaller than rust I've seen.  Plus, there are no cedars anywhere near here.

The one shot is a zoomed magnification.  To give perspective, they are smaller than a grain of salt.

I think I am just going to dispose of it.  Searched everywhere and just can't seem to get a positive ID on this--what appears to be--a fungus under the microscope.
