Abstract/Contents: | "Compared to other turfgrass species, very few herbicides are registered for use in seashore paspalum (Paspalum vaginatum O. Swartz). Currently, only three preemergence (prodiamine, dithiopyr and oxadiazon) and two postemergence (halosulfuron, carfentrazone + 2,4-D + MCPP + dicamba) herbicides are labeled for this turfgrass. While these herbicides are useful, additional herbicides will be necessary to control the wide range of weed species that potentially will be found in seashore paspalum. Two separate experiments were conducted with foramsulfuron and flazasulfuron on 'Sea Isle I' seashore paspalum in Griffin, GA in 2004. Flazasulfuron at a rate range of 0.5 to 3.0 ozs. product/acre was applied to separate plots on May 5 and July 6, 2004. Foramsulfuron at rates that ranged from 4.4 to 52.4 fl. ozs. product/acre was applied as a single application on May 5 and as a repeat application on July 6 fb July 13, 2004. Flazasulfuron at rates <= 1.5 ozs./product acre caused only minor (< 12%) injury for two to three wks to seashore paspalum. Seashore paspalum tolerance to foramsulfuron was highly rate dependent. Foramsulfuron rates above 8.8 fl. ozs. product/acre injured seashore paspalum > 35% for 2 to 3 wks following single or repeat applications. Seashore paspalum seedhead emergence was suppressed > 80% for approximately four wks with flazasulfuron at rates > 1.0 oz./acre. Single and repeat applications of foramsulfuron at rates of >= 17.4 ozs./acre were highly effective for seedhead suppression up to 6 wks after application. Rates as low as 8.8 ozs./acre applied July 6 fb July 13 suppressed seedhead emergence for up to 5 wks after application. 'Sea Isle I' seashore paspalum exhibited excellent tolerance to metsulfuron at 1.0 oz. product/acre. Metsulfuron did not suppress seedhead emergence." |
