Q.Should I Treat My Flowering Pear Tree For Rust Fungus If All The Trees In The Area Have It?

Zone 6 | native_species added on September 8, 2022 | Answered

I have a non-fruiting flowering pear tree that has rust fungus. I had a tree specialist out to look at it, and he said the tree can be saved, but he can\’t treat it for rust until spring. Is there any point in treating it if there are 7 or 8 other pear trees with the same fungus in my neighbors\’ yards nearby? If my neighbors don\’t all treat their trees, will it just spread back to mine? The tree specialist said rust is in the entire area. Should I simply replace the tree with something else that\’s resistant to this fungus? You can see in the picture how close some of my neighbors\’ pear trees are to mine.

Oooooh.... Yea, that is what I would do. This will be chasing your tail, unfortunately. Sorry.

As long as the guy is sure that it is Gymnosporangium sabinae... Then you could try some cherry cultivars. There should be no issue, here.
