| Abstract/Contents: | Presents a study conducted to "determine the efficacy of varying nozzle types (droplet size) to apply Primo MAXX and Primo WSB using color ratings and measurements of plant height and foliar fresh weight yield." States that "this study was conducted on a mature stand of creeping bentgrass (Agrostis stolonifera) and annual bluegrass (Poa annua). Details methods and materials used in the study, stating that "this study was a randomized complete block design with three replications. The plot size was 40 ft2 [square feet]. All treatments were applied on June 8 and June 23, 2005 using a four foot battery powered walk behind boom sprayer calibrated to deliver 1 (all treatments except nozzle TT11006) or 2 gpm [gallons per minute] using two nozzles of varying types/droplet size at 40 psi [pounds per square inch]." Reports that turfgrass color was never rated below acceptable. The lowest turfgrass color rating during the study was 7.8 on the first rating date (June 15, 2005). There were only slight color differences between treated and untreated turfgrass....turfgrass treated with Primo MAXX at 0.125 oz/M [ounces/1,000 square feet] with an XR Tee Jet XR11003 nozzle had significantly lower height than untreated." |
