| Abstract/Contents: | "The objective of this research was to determine if applications of glyphosate [N-(phosphonomethyl) glycine]; glufosinate ammonium [butanoic acid, 2-amino-4-(hydroxymethylphosphinyl) - monoammonium salt]; diquat dibromide [6,7-dihydrodipyrido (1,2-a:2',1'-c) pyrazinediium dibromide]; and pelargonic acid applied alone or in various combinations can be used to provide fast and complete control of tall fescue (Festuca arundinacea Schreb.) and Kentucky bluegrass (Poa pratensis L.) turf. Glyphosate, at 3.4 and 2.2 kg ai ha-1, resulted in the most consistent control of tall fescue and Kentucky bluegrass, respectively, compared to all other treatments following late spring and late summer applications in 1999 and 2000. The glyphosate (3.4 kg ai ha-1)/pelargoic acid (12.3 kg ai ha-1) treatment provided control of tall fescue equivalent to that of glyphosate (3.4 ai ha-1) at 42 d after applications on some dates, but not on others. Glyphosate (2.2 kg ai ha-1)/glufosinate ammonium (1.7 kg ai ha-1) showed control symptoms on Kentucky bluegrass sooner than glyphosate (2.2 kg ai ha-1) at 1, 4, and 8 d after late spring and late summer applications in 1999 and 2000, and provided control equivalent to glyphosate (2.2 kg ai ha-1) at 42 d following late summer applications in 1999 and 2000. However, this treatment did not provide adequate control of Kentucky bluegrass 42 d following late spring applications. Results of this study suggest that glyphosate is the most prudent choice for turfgrass managers considering complete renovation of Kentucky bluegrass and tall fescue turf." |
