| Abstract/Contents: | "Common reed [Phragmites australis (Cav.) Trin. ex Steud.] has overtaken wetland areas across the northeast. Studies were conducted in containers and at two field sites to evaluate mowing, with or without herbicide application, for phragmites control. Certain plots were mowed every 2, 4 or 8 weeks. One set of plots received an application of glyphosate at 2% V/V. Glyphosate was also applied either two weeks prior to a single mowing or at 4 weeks after one mowing. Experimental design was a randomized complete block with four replications. In the container trials, phragmites was grown in 1- gallon pots of pine bark, with 3 pots per plot. Phragmites was 3 feet tall at initiation of the trial. At three months after study initiation, all treatments containing glyphosate gave complete control of phragmites. Phragmites shoot weight and shoot number decreased as mowing frequency increased. Cutting every 2 weeks gave excellent control of common reed. Cutting every 8 weeks did not provide acceptable control. In the field trials, phragmites was four to nine feet tall at study initiation. Plots were mowed with a weedeater fitted with a saw blade. Percent control and phragmites shoot count were recorded on September 4, 2001, 4 months after initiation of the trial. Phragmites shoots were counted and weighed in May of 2002, one year after trial initiation. In the field mowing trials, mowing every 2 weeks resulted in 90 to 95% control of giant reed in early September, with approximately 80% control seen with mowing every 4 weeks. Mowing every 8 weeks gave 70% control. For all mowing treatments, however viable phragmites stems were observed at the end of the growing season. When evaluated the following May. considerable regrowth was observed in mowed plots. Reduction in phragmites shoot weight in May ranged from 35 to 77% with the mowing treatments that did not receive a glyphosate application. When evaluated in early September, glyphosate applied in combination with a single mowing provided good to excellent control of phragmites. Applying glyphosate prior to mowing provided similiar control compared to applications made one month after mowing. Addition of mowing appeared to improve control over glyphosaate applied without mowing when evaluated in September. Glyphosate applied alone provided 75 to 88% control of common reed, while combining mowing with glyphosate resulted in 84 to 96% control, depending upon location, at this time. However, when evaluated in the following May, glyphosate applied alone appeared to give slightly greater control than when applied with mowing, although the results were not statistically different. Glyphosate applied without mowing gave 93 to 95% reduction in phragmites shoot weight the following may. Glyphosate applied in conjunction with mowing gave 87% to 93% reduction in phragmites shoot weight in May. Glyphosate, applied with without mowing, provides excellent but not complete phragmites control one year after a single application. Mowing frequently will suppress this weed. However, maintaining a regular mowing schedule for one growing season will not provide acceptable control of phragmites the following season." |
