Hello, someone told me that my spruce trees may have Spruce budworm or Needle Blight. I read about it on this UofM website. wondering A. is this indeed the issue? B. if so, what product do I treat it with C. where do I purchase the product? Thanks so much for your service and help! :) Paul
The front tree may be normal as needles are dropped in different year intervals, the back one kind of looks like Rhizosphaera needlecast (Rhizosphaera Kalkhoffii) check http://web.extension.illinois.edu/plantclinic/downloads/Plant%20Clinic%20Report%20Spruce.pdf for more information.
