With the registration of Parlay (Plant Growth Regulator) in perennial ryegrass, growers are now interested in the potential of using the product in other grass seed crops.  The Manitoba Forage Seed Association has spent several years  examining the use of Parlay in a broad range of grass seed crops to examine the potential for registration. Grass seed crops that were examined for the use of Parlay were:  Hybrid brome, Tall fescue and Timothy.
