IMHO it is the amount of over seeding that effects spring green up. IMHO anything over 4 pounds per thousand of rye will stunt the perennial turf in the spring by out competing it. MSME is about the only herbicide that control rye grass and should be applied just as the weather breaks for spring green up. BTW MSME is slow to show response, therefore timing becomes even more critical.
