Abstract/Contents: | "Organic weed control options for turfgrass systems remain in high demand. For annual bluegrass (Poa annua), the problem has intensified because of resistance to many once-effective synthetic herbicides. Although there are few products and strategies that are labeled as organic options, the viability, practicality, and efficiency of these alternative strategies for weed control in turfgrass system is poorly understood. Field trials were conducted during the 2020 growing season at Virginia Tech's Glade Road Research Facility in Blacksburg, VA, to examine the efficacy of alternative strategies for annual bluegrass control in perennial ryegrass and tall fescue turf. The organic treatments included hand weeding, boiling water, flaming, sod replacement, solarization (4000 W/m2 ), solarization (8000 W/m2 ), and shading (six weeks). Also, were included a selective herbicide (Methiozolin) and a non-selective herbicide (Glufosinate) as a standard treatment, and a nontreated check. All treatments were replicated four times and herbicides were applied with a CO2-powered boom sprayer calibrated to deliver 40 gal/ac. Results from these trials indicate that manual weed control and sod replacement may be great options, but may be cost prohibitive. Shading was minimally effective at controlling annual bluegrass and may require more than six weeks disruption of turf use. Solarization appears to be seasonally dependent such that cool, low-radiation, conditions in spring will be less effective than warm, highly radiant summer conditions. Flaming and Boiling-water treatments controlled all turf vegetation greater than or equal to glufosinate. Among these nonselective treatments, boiling water resulted in less subsequent weed germination than flame and overall quicker tall fescue and perennial ryegrass recovery compared to flame or glufosinate" |
