| Abstract/Contents: | "Japanese stiltgrass (Microstegium vimineum) (JSG) is a nonnative, grassy weed that has become a severe problem in the Eastern United States. Native to Asia, JSG was introduced to the US in 1919 and can thrive in various types of environments from New York to Florida, including wetlands, woodlands, lawns, landscape beds, and mountainous regions. Due to its flexible habitat tolerance and ability to grow under both shade and full sunlight, JSG is threatening native understory species. Research has been conducted to determine the most efficient and economic chemical or mechanical methods to control JSG. Studies in the past have used selective herbicides and mechanical controls, including fenoxaprop, imazapic, sethoxydim, mowing, hand pulling, and others to evaluate JSG control in natural areas such as wetlands and forest but not in a lawn or turf setting. Our study in Newport, Virginia was conducted on a residential lawn to determine the most effective chemical means to control JSG without injuring the desired turfgrass. The trial was initiated on August 15, 2014 on a mixed Kentucky bluegrass (Poa pratensis) and tall fescue (Lolium arundinaceum) lawn. Treatments included: mesotrione at 280 g ai/ha-1 once, mesotrione at 140 g ai/ha-1 twice, topramezone at 57 g ai/ha-1 once, topramezone 24 g ai/ha-1 twice, quinclorac at 1120 g ai/ha-1 once, quinclorac at 660 g ai/ha-1 twice, fenoxaprop at 140 g ai/ha-1 once, fenoxaprop at 70 g ai/ha-1 once, fenoxaprop at 35 g ai/ha-1 once, triclopyr at 1120 g ai/ha-1 once, mesotrione at 280 g ai/ha-1 + triclopyr once, topramezone at 54 g ai/ha-1 + triclopyr once, and all treatments included an adjuvant(NIS or MSO) except fenoxaprop and triclopyr. These treatments were applied with a hooded sprayer at 45 L/ha-1 and 4.8 km/h, and the sprayer had a 71.12 cm spray width. Initial JSG cover in the lawn plots ranged from 30 to 80%. At 3 WAIT, mesotrione, quinclorac, and triclopyr controlled JSG less than 40%. Topramezone at 24 g ha-1 , combinations of topramezone or mesotrione with triclopyr, and fenoxaprop at 14 or 28 g ha-1 controlled JSG at least 67%. AT 6 WAIT, JSG had recovered from most treatments. Fenoxaprop at any rate completely controlled JSG. All topramezone-containing treatments controlled JSG >70%, and higher than the remaining treatments." |
