| Abstract/Contents: | Reports results of three tests regarding the effects of turf herbicides on five cultivars of seashore paspalum, 'Adalayd' and 'Futurf'. Those herbicides tested include 2,4-D amine, dicamba, MSMA, Quadmec, Triclopyr, DCPA, oxadiazon, Trimec ester, bensulide and pronamide. In study 1 pronamide and bensulide did not cause any early phytotoxic effects on 'Futurf'. Label rates of 2,4-D amine and dicamba caused slight to moderate turf yellowing, but was temporary and regrowth was normal. In study 2, phytotoxicity was not observed with any of the four preemergence herbicides, benefin, DCPA, bensulide or oxadiazon applied annually in February over a two-year period. In study 3 one week after the first application of herbicides, plotys of both 'Adalayd' and 'Futurf' treated with MSMA and Quadmec exhibited phytotoxicity. Trimec ester also caused a slight phytotoxic effect on 'Futurf' only. A month later phtotoxic effects caused by MSMA, Quadmec, Triclopyr and Trimec were observed. Triclopyr and Trimec damage to turf was less severe than either MSMA or Quadmec. Includes charts showing phytotoxicity of the tow cultivars to the different herbicides, and the effects of turf herbicides on Seashore paspalum and seehead production. "In conclusion, results from these studies indicate MSMA and the MSMA containing Quadmec are not safe to use on seashore paspalum. The herbicide 2,4-D amine gave some injury in early spring applications (Study 1), but not in late June (Study 3). After a second application in Sept., however, injury was very apparent at 2 time the label rate. The label rate of 1 lb ai/A application only produced slight yellowing inury in both trials. Dicamba at 0.25 pounds per acre was safe to the turf in both trials. Dicamba at 0.25 lb ai/A was safe to the turf in both studies. Excessive rates of dicamba gave a slight turf rsponse but were not significant. Triclopyr gave some turf injury after one month. The mixture of 2,4-D, MCPP and dicamba (Trexsan) gave injury at the high rates used." |
