| Abstract/Contents: | "Weed control in dormant bermudagrass (Cynodon dactylon L. Pers) is not a new problem for turfgrass research. One grass species that is a problem for bermudagrass lawns in the trasition zone is tall fescue (Festuca arundinacea). To evaluate control of tall fescue we tested glyphosate (4.48, 2.24, 1.12, and 0.56 kg ai/ha-1) in combination with a surfactant (Frigate 1/2%). In addition, two rates of sulfometuron methyl (0.053 and 0.026 kg ai/ha-1), single rate each of atrazine and simazine (both at 2.24 kg ai/ha-1) were applied separately and in combination with 0.56 kg ai/ha-1 glyphosate + suractant (1/2%). These same chemicals were applied to two additional grass species, Benson Kentucky bluegrass (Poa pratensis L.) and Regal perennial ryegrass (Lolium perenne L.), and were evaluated for control of the species and bermudagrass release. There was also a study involving glyphosate (2 kg, 1 kg ai/ha-1) at three different spray volumes. Data collected included injury and percent cover of both cool season species and bermudagrass. Glyphosate at the upper rates controlled tall fescue in the spring and prevented regrowth in the fall. Atrazine-treated plots behaved in a similar manner. Sulfometruon methyl controlled tall fescue adaquately but prevented the release of bermudagrass at greenup time. All rates of glyphosate and atrazine controlled both Perennial ryegrass and Kentucky bluegrass. Sulfometuron methyl had no effect on Kentucky bluegrass other than discoloration injury for a short period. The surfactant used showed no significant difference in any part of the study. There was no significant difference in the spray volumes." |
