Sick Roddy?

Asked September 27, 2017, 8:40 PM EDT

Hi, We've had white spots appear on the limbs of our roddys. They are not raised, not moist, and almost appear to be areas of bark scraped off. It appeared a couple of weeks ago and has spread, ot at least had appeared, on several other roddys in the same row, Leaves look OK Any idea what it might be and treatment/ Pics attached Thanks!

Not likely a problem at all. These look like crustose type lichens. They are not pathogenic but just using the stems to support growth. You can find them on a lot of different woody plants and other locations. You can read about them here:
