Post Emergence Control of Liriope spicata

摘要

Liriope spicata is an evergreen groundcover classified as a perennial, popularly found in the ornamental landscape setting. L. spicata is commonly referred to as creeping liriope, creeping lilyturf, and creeping monkey grass. Native to eastern Asia, creeping liriope spreads aggressively through an underground rhizome root formation. L. spicata is cited under at least six listings as an invasive species (Bugwood, 2010). When incorporated into the homeowner landscape, the aggressive nature of L. spicata can become a problematic maintenance issue when trying to contain an area of establishment. Listed as an exotic forb species by the Invasive Plant Atlas of the United States, creeping liriope has been reported to be invasive in natural areas within theU.S. (Spaulding et al., 2010). As an escaped species from cultivation, the possibility of L. spicata affecting the natural growth areas of our native lands and forests can have a significant impact (Swearingen, 2009). Little research has been documentedon the control methods of L. spicata within the horticulture industry. Most available control measures recommend mechanical removal with the addition of herbicide applications such as glyphosate or impazapyr (Miller et al., 2010).
