Hello,
Do the leaves of your plant also have spots on them? There are some diseases that can cause spotting on stalks, but the leaves would also likely be affected. Look at this information below and see if this information matches with what you are seeing on your plant.

If it does not seem like it fits, feel free to bring a sample into the Yamhill County Extension office and Master Gardeners can assist you with a diagnosis.
