Poison Ivy Parasite or Disease?
While working in the yard yesterday evening I noticed an unusual looking poison ivy plant. The leaves were covered with small nodules that I'm guessing was some type of parasite or disease and it appeared the infestation was so severe the plant was dieing off. Surrounding plants didn't appear affected by the condition - although admittedly there was only trumpet vine and grass in the area. Younger poison ivy plants did, however, to have the condition as well.
Has anyone ever encountered this before on poison ivy?
It struck me that if this was a condition that perhaps only affected poison ivy that maybe it could be isolated and used as a biocontrol for the plant. A Google search of "poison ivy parasites" (or similar) didn't lead me to any hits.
I apologize if the attached picture isn't up to par. Size limitations.
Any suggestions on how or if I should proceed.
