Jessie,
I surely don't have an answer but have witnessed rye grass contaminated greens before. No reason to say where but it was in the southern Rocky Mountains at a fairly moderate elevation. If I recall correctly, the staff had used a seeder spiker unit on some tees, didn't get it completely cleaned out and then spiked some seed into greens as well.
A couple issues came to my mind as well, the seed gates had to be too far open for bentgrass if spiking it in, that rye shouldn't have even fit down the hole. And why o why not shop vac the seeder out. Needless to say, it was in a pattern and doing well. I wish I could remember the maintenance practices, but it's been a decade or so.
I guess one question hasn't been asked, how contaminated are these surfaces? Are we talking the perimeters of the greens, all the way through the putting surface, just a spot here and there? All 18, one or 2, can you please define a little more?
