| Abstract/Contents: | "Zoysiagrass is widely recognized for its slow establishment from sprigs, plugs, or seed. Bermudagrass, for example, requires a few months to achieve complete green cover from sprigs while zoysiagrass can require two growing seasons. Recent advancements in fraze mowing technology have led to several innovations in turfgrass agronomic management. One side effect of fraze mowing is production of large amounts of vegetative material and soil as spoils from the fraze mowing process. This debris is often discarded. Preliminary evaluations have demonstrated rapid turf establishment when bermudagrass fraze mowing spoils were spread for the purpose of establishing new turf areas. Empirical observations suggest that a 30 to 40% improvement on bermudagrass establishment time can be achieved when using fraze mowing spoils versus conventional sprigs. If this technology could be applied to zoysiagrass with similar improvement in establishment time, the technique would offer a valuable solution to the slow zoysiagrass establishment problem. During any warm-season turfgrass establishment, herbicides are needed to maximize establishment rate by excluding unwanted weeds. Our objectives were to determine zoysiagrass establishment rates from seed, plugs, sprigs, and fraze mowing spoils and to assess how uniformly-applied herbicide treatments may influence establishment rate depending on propagule type. A field study was established on May 4, 2018 and spoils, plugs, sprigs, and seed were applied at 5 m3 ha-1 , 10% cover, 10% cover, and 96 kg ha-1 , respectively. Halosulfuron at 0.021 kg ha-1 and quinclorac at 0.42 kg ha-1 were applied on May 21, a premixture of halosulfuron + foramsulfuron + thiencarbazone was applied at 0.135 kg ha-1 on July 2, and quinclorac at 0.84 kg ha-1 was applied on August 25. Herbicides did not unacceptably injure or negatively influence establishment of zoysiagrass on any date. Zoysiagrass establishment rate exhibited the following trend from most to least rapid: seed > plugs > sprigs > spoils. Fraze mowing spoils resulted in only 10% zoysiagrass cover by November 2 while seed, plugs, and sprigs had 92, 80, and 78% cover, respectively. These data suggest that fraze mowing spoils may not be an effective method to establish zoysiagrass." |
