| Abstract/Contents: | "CGA 163935 was evaluated for its growth regulating effect on common bermudagrass for two years and `Tifway' bermudagrass for four years. The vegetative growth of mowed common bermudagrass was suppressed for 5 wk when CGA 163935 was applied at 0.2 kg ha-1 followed by 0.1 kg ha-1 2 wk later and mowed Tifway bermudagrass was suppressed for 4 wk after application of 0.2 kg ha-1. CGA 163935 suppressed vegetative growth of non-mowed common bermudagrass for 9 wk and non-mowed Tifway bermudagrass for 2 to 8 wk at the same rates. Common bermudagrass tolerated CGA 163935 when aplied initially at 0.2 kg ha-1 and followed by 0.1 kg ha-1 at a 2-wk interval for a total of 0.3 kg ha-1 rate. However, common bermudagrass was severely injured (> 30%) when CGA 163935 was applied at 0.2 kg ha-1 in each of two applications for a total rate of 0.4 kg ha-1. Tifway bermudagrass tolerated CGA 163935 when applied at 0.2 kg ha-1 as a single application or when the 0.2 kg ha-1 was followed by 0.1 kg ha-1 at a 4-wk interval. Tifway bermudagrass was severely injured (> 30%) when CGA 163935 was applied at 0.4 kg ha-1 as a single application or when 0.2 kg ha-1 was followed by 0.1 kg ha-1 at 2- or 3-wk interval. Seedheads were suppressed in common bermudagrass for 1 to 2 wk with CGA 163935 at 0.4 kg ha-1." |
