This is an infection on Eucaliptus globulus in my garden The tops of the tree are like this, and one of the eucaliptus barks is like a resin. Will it infect the other trees exept eucaliptus? How are they called and is there a solution?Thank you
it looks like it. I opened them but I do not have a microscope to see it in details. All the eucaliptus tree are infected at the tops, the new branches.
