Spotted leaves, Pear Tree
We’ve just planted a couple Bartlett pear trees a few weeks ago. Now the leaves are beginning to come out after blooming and one branch has rusty spots on it. Could be pear rust? Just wondering if they should be sprayed right away, maybe removed before it spreads to more branches? Thank you for your help!

A spray won't help this season because the damage is already done. Our official plant disease handbook suggests "Plan on taking action the following fall or spring. . ."
