| Abstract/Contents: | "Herbicide efficacy among seashore paspalum (Paspalum vaginatum Swartz) ecotypes during establishment is not well documented. When herbicides were applied to eight newly planted paspalum cultivars, herbicide tolerance among cultivars was not different. Neither Manage (halosulfuron) at ≤0.21 kg/ha (≤0.19 lb/A) not Ronstar (oxadiazon) at ≤10.0 kg/ha (≤9.0 lb/A) caused significant turfgrass injury when applied at the recommended or three times the recommended rates during 1996 and 1997. Similar results were obtained from Drive (quinclorac) at 0.9 kg/ha (0.8 lb/A) and Vanquish (dicamba) at 0.6 kg/ha (0.5 lb/A). In 1996, Dimension (dithiopyr) and pendimethalin rates were applied in 1997, Dimension (dithiopyr) caused a maximum of 19% injury [0.6 kg/ha (0.5 lb/A)] and pendimethalin caused a maximum injury of 23% [3.3 kg/ha (3.0 lb/A)]. The injury was 35 to 36% when each herbicide was applied at three times the recommended rate. Illoxan (diclofop) at ≥1.1 kg/ha (≥1.0 lb/A) was the only herbicide included in this study that severely injured the turfgrass (26 to 42%) both years when applied at the recommended rate. Differences were found in growth among eight paspalum cultivars during the 6-week period following planting. By 6 weeks, SIPV-2 generally produced the poorest growth in 1996 while Adalayd produced the poorest growth in 1996 and 1997." |
