pear rust

  While walking in German Village in Columbus with ONLA’s Frits Risor last week we revisited the Callery pears with rust disease noted earlier this season (http://bygl.osu.edu/node/342).

As earlier, the two trees in question were speckled with bright orange lesions on the upper leaf surfaces, but I suspected that by now the rust fungus would have undergone sexual reproduction in the leaves with aecial spore pustules developing  on the lower leaf surfaces as would be seen with the cedar-apple rust fungus (...

I was much surprised to see what I think are Callery pear trees speckled with bright orange-red rust symptoms in German Village in Columbus this past week, however.
