| Abstract/Contents: | "In North Carolina, imazapic (Plateau) and imazapic + 2,4-D (Oasis) were evaluated on a `Coastal' bermudagrass pasture for yield effects in 2000. A 'Tifton 44' bermudagrass pasture was treated with Oasis in 2000 and with Plateau and Oasis in 2001 for yield and hay quality effects. the 'Coastal' bermudagrass trial consisted of a nontreated check with and without 30% N carrier, Oasis at 4 and 6 oz / acre in 30% N carrier, Oasis at 4 oz / acre in water carrier and Plateau at 4 oz / acre in 30% N carrier. Treated plots also received X-77 Spreader at 0.25% v/v and were applied on August 23, 2000. Plots were harvested on October 4, 6 weeks after treatment (WAT). Oasis was applied to `Tifton 44' bermudagrass on May 23, 2000 at 4 and 6 oz / acre. X-77 Spreader was added at 0.25% v/v. Plots were harvested on June 21, July 28, and October 4 (4, 9 and 19 WAT, respectively). Yield effects were evaluated as well as quality effects consisting of predictions for neutral detergent fiber (NDF), acid detergent fiber (ADF), hemi-cellulose and crude protein (CP). Plateau and Oasis, at 4 and 6 oz / acre each, were applied to `Tifton 44' bermudagrass on June 27, 2001. X-77 Spreader was added at 0.25% v/v. Plots were harvested on August 14 and October 1 (7 and 14 WAT, respectively). Yield and quality effects were evaluated. The addition of 30% N to the nontreated `Coastal' bermudagrass check increased 1st cut yields by 22% over the nonfertilized check. All Plateau and Oasis treated plots produced yields that were approximately 50% of the fertilized check plots. `Tifton 44' bermudagrass quality (NDF, ADF, hemi-cellulose and CP) was not affected by any treatment in 2000 and 2001. In 2000, 1st cut yields of `Tifton 44' bermudagrass were reduced approximately 75% by either Oasis rate while total production was reduced 22 to 24%. In 2001, 1st yields of `Tifton 44' bermudagrass were reduced 20 to 30% from either of the Plateau or Oasis treatments. Total production was reduced up to 20% in Oasis treated plots and in plots treated with Plateau at 6 oz / acre. These data suggest that `Tifton 44' bermudagrass quality is not affected by Plateau or Oasis at 4 to 6 oz / acre. These treatments cause a yield decrease from 1st cut after application in `Coastal' and `Tifton 44' bermudagrass with total production not being able to completely recover by season's end." |
