Abstract/Contents:"The family Juncaceae includes several turfgrass weeds. Two particular species that are problematic in the southeastern and gulf-coastal United States are path rush (Juncus tenuis) and toad rush (J. bufonius). These are formidable weeds because of their ability to survive a myriad of environments unfavorable to turfgrass, including drought, flooding, and compaction. Path rush, a deep-rooted perennial, reproduces by rhizomes and seeds. Though similar in appearance, toad rush is an annual and has not been reported to propagate by vegetative structures. Prior research examining means of controlling these species is limited, and has largely focused upon repeat applications of 2,4-D alone or in mixture with other auxin mimicking herbicides. Juncaceae are closely related to Cyperaceae, the sedge family; therefore, research conducted at Mississippi State University and the University of Tennessee screened common sedge herbicides for potential control of path and toad rush. The herbicides flazasulfuron, halosulfuron, and the three-way combination of thiencarbazone-methyl, foramsulfuron, and halosulfuron, were generally effective means of controlling both species; however, results were varied due to timing and location. Results from these studies led to several hypotheses, including: that herbicide efficacy is affected by application timing, and that rush species/populations differ in their response to tested herbicides. Rate response studies suggest that these two species vary in response to applications of halosulfuron or 2,4-D. Albeit preliminary, results also indicate that path rush populations may vary in susceptibility to 2,4-D. Results of a two year field study indicate that control of path rush varies due to application timings tested (monthly, October to March). Applications made in October controlled path rush greater than all other application timings in this study, albeit only 60% control was achieved. In greenhouse studies of shoot and root biomass accumulation, increasing soil bulk density reduced biomass accumulation, while increasing volumetric water content increased biomass accumulation."
