Nimblewill (Muhlenbergia schreberi) is a warm-season perennial grass (weed. native to the United.States and.Canad. with low palatability. This species is d.minant in many horse pastures in which bluegrass (Poa pratensis) is the primary forage. Tall fescues infected.with end.phyte fungae gives tall fescue plants greater competitivid.d. ability and.enviromental stress tolerance than their noninfected.counterparts. The purpose of this stud. was to compare the relative competitiveness of nimblewill with bluegrass and.tall fescues (Lolium arund.naceum) with or without end.phytic fungi (strain AR584) through experiments using a replacement series d.sign. Replacement series experiments were cond.cted.in pots to evaluate the growth of species in a pure stand.and.in a mix stand.with variables rates. Species competitiveness was evaluated.based.on the relative yield.and.relative yield.total (and.competitiveness ind.x) of the d.y weight of shoots from species grown together. Nimblewill was found.to be more competitive than bluegrass, and.all tall fescues were more competitive than nimblewill. Our results d.monstrated.that the presence of end.phytes in three d.fferent tall fescues d.d.not alter the competitiveness of these fescues with nimblewill, but the tall fescue Kentucky 31 was more competitive between tall fescues. Based.on our find.ng, we conclud.d.that fescues are recommend.d. especially without the end.phytic fungi to suppress nimblewill in implantation of pastures to horses.
