![]() ![]() Although the grass can be grown on salt water (which is a natural weed killer) or gray water, it does much better on high quality fresh water. Even the sales rep from the licensing company advised to stay away from it unless you NEED it, i.e., you are on the ocean’s edge. Seashore Paspalum – Not hearing good results from anybody on the mainland with this – great marketing program – poor real performance. I live in Southeast Florida, I have well drained sandy soils and full sun. My choices, as I see it, are Bermuda, Zoysia or Sea Shore Paspalum. These data identified oxadiazon, oxyfluorfen, and sulfosulfuron as safe and effective for establishing transplanted seashore dropseed plugs.I am finilizing my lawn and am trying to create a nice, well maintained grass area (about 800 sf). An unintended overapplication of aminopyralid was phytotoxic, but it did not lead to complete plant death at 28 DAH2. The mixture of carfentrazone + (4-chloro-2-methylphenoxy)acetic acid + mecoprop + dicamba and triclopyr were the most injurious to seashore dropseed and should only be used as a directed spray treatment. The postemergence herbicide sulfosulfuron was the least injurious to seashore dropseed. Although all pre-emergence herbicides (except table salt) exhibited acceptable weed control ratings, only oxadiazon and oxyfluorfen showed exceptional weed control and safety. Crop response to postemergence herbicides aminopyralid (1.10 lb/acre a.i.), triclopyr (3.0 lb/acre a.i.), a prepackaged mix of carfentrazone + (4-chloro-2-methylphenoxy)acetic acid + mecoprop + dicamba (0.02 + 1.11 + 0.22 + 0.11 lb/acre a.i.), and sulfosulfuron (0.06 lb/acre a.i.) applied at 70 and 98 DAT included visual foliar injury ratings and aboveground biomass accumulation at 28 DAH2. ![]() Preemergence weed control with crop response measures as visual foliar injury ratings and aboveground biomass accumulation were recorded 38 days after the second application of herbicides (DAH2). Dithiopyr (0.25 and 0.50 lb/acre a.i.), trifluralin + isoxaben (2.0 + 0.5 and 4.0 + 1.0 lb/acre a.i.), oxyfluorfen (0.25 and 0.50 lb/acre a.i.), oxadiazon (2.0 and 4.0 lb/acre a.i.), and granular table salt (99% sodium chloride, 1% sodium silicoaluminate 83% of particles 0.5–0.25 mm in diameter, 400 lb/acre a.i.) were applied at 2 and 84 days after transplanting (DAT). Seashore paspalum turf bleaching from mesotrione and topramezone can be reduced with the addition of metribuzin and/or ethofumesate to the tank mix.įield experiments were conducted to assess the tolerance of seashore dropseed (Sporobolus virginicus) to pre- and postemergence herbicides labeled for roadside right-of-way use. Applications of mesotrione did not result in goosegrass control. ![]() Maximum bermudagrass injury was seen in treatments with mesotrione (0.07 kg ha-1) and/or ethofumesate (1.12 kg ha-1). Incorporating a post-spray dry down allowed for complete control of goosegrass with one spray application. Goosegrass was controlled with tank mixes that included topramezone (0.01 kg ha-1) + metribuzin (0.10 kg ha-1) with an acceptable level of seashore paspalum discoloration. The herbicides metribuzin, topramezone, mesotrione, and ethofumesate were evaluated in tank mixtures for bermudagrass and mature goosegrass control and seashore paspalum injury. Herbicide efficacy studies were conducted at the West Loch Golf Course ('Salam' seashore paspalum, greens cut) on the island of Oahu in Hawaii. Bermudagrass and goosegrass are problem weeds infesting both fairways and greens on many seashore paspalum golf courses. Seashore paspalum has gained increased popularity in Hawaii due to its salt tolerance and the use of non-potable water on golf courses. ![]()
