Abstract/Contents:"A field study was conducted on tolerance of four seashore paspalum cultivars to postemergence (POST) herbicides in Georgia during 1995 and 1996. Quinclorac (0.8 kg/ha) and MON 12000 (0.07 kg/ha) at recommended rates were the only POST herbicides that did not affect the performance of any seashore paspalum cultivar (≥89%). When the rates were increased to three times recommended, the quality of 'AP 10' (≥96%) and 'PI 28960' (93%) cultivars was not affected, but the quality of 'HI 25' (≥84%) and 'K-7' (77%) was lower when compared with respective untreated plots. HI 25 recovered within 4 wk, but K-7 required 6 wk or longer. Dicamba at 1.7 kg/ha affected the quality of K-7 (69%) more at 2 wk than the other cultivars (85 to 92%). Diclofop, imazaquin, and 2,4-D plus mecoprop plus dicamba significantly reduced the quality of all cultivars 2 wk after treatment (WAT). The quality of all cultivars was similar at 2 WAT with diclofop at 1.1 kg/ha (79 to 84%). However, when treated with imazaquin at 0.4 kg/ha, the quality of K-7 (65%) was lower than AP 10 (85%), HI 25 (77%), and PI 28960 (81%), and when treated with 2,4-D plus mecoprop plus dicamba at 1.1 + 0.6 + 0.1 kg/ha, the quality of AP 10 (75%), PI 28960 (72%), and K-7 (57%) was lower than HI 25 (87%). POST applications of quinclorac, dicamba, and MON 12000 were safe to use for weed control in paspalum cultivars, whereas the safety of diclofop and imazaquin was marginal, and 2,4-D plus mecoprop plus dicamba was unacceptable."
