| Abstract/Contents: | "Jointhead grass (Arthraxon hispidus (Thunb.) Makino) is a low-growing sprawling, annual grass native to East and Southern Asia. Since its introduction in the 1970's, it has been reported in 28 states with the majority being located in the eastern United States. It is primarily a weed in pastures, ditches, roadsides, and turfgrass settings. Little to no previous research has been conducted examining jointhead grass control options in a cool-season turf setting. Therefore, research was conducted to evaluate commonly used postemergence herbicides for control of jointhead grass and safety on tall fescue (Schedonorus arundinaceus (Schreb.) Dumort., nom. cons). Two separate trials were initiated in Blacksburg, VA during the summer of 2016. The first trial was initiated June 10, 2016 on a tall-fescue roadside. The second trial was initiated July 14, 2016 on lawn height tall fescue. Treatments for both trials were arranged as a randomized complete block design with three replications. At 4 weeks after treatment (WAT), mesotrione at 0.28 kg ai ha-1 applied twice at a three-week interval, MSMA at 2.24 kg ai ha-1 applied twice at a two-week interval, fenoxaprop at 0.14 kg ai ha-1 , topramezone at 0.024 kg ai ha-1 applied twice at a three-week interval, and indaziflam at 0.067 kg ai ha-1 controlled jointhead grass 80% or more. Sulfentrazone at 0.28 kg ai ha-1 initially discolored jointhead grass but regrowth began within 3 WAT. While MSMA controlled jointhead grass, it injured tall fescue 75% and significantly reduced turf quality and turf cover. At 7 WAT, plots treated with MSMA had recovered and no injury was visible. Data from the two sites indicate that among herbicides registered for use in lawn turf, fenoxaprop, mesotrione, and topramezone can selectively control jointhead grass in tall fescue turf. Indaziflam and MSMA also control jointhead grass but are either injurious to tall fescue turf or not registered. The data further suggest that dithiopyr, fluazifop, quinclorac, and sulfentrazone may suppress but do not control jointhead grass in tall fescue turf." |
