CLEVELAND MUSEUM OF NATURAL HISTORY - 2016 - Frequently Asked Questions About Phragmites australis (Common Reed Grass) Biological Invasions 17/07/17 Management of invasive Phragmites australis in the Adirondacks: a cautionary tale about prospects of eradication. Our results of treating invasive P. australis in the Adirondacks offer both encouragement and reason for caution for those managing the species.

Biological Invasions 17/07/17 Management of invasive Phragmites australis in the Adirondacks: a cautionary tale about prospects of eradication

Eradication is clearly a possibility when addressing small infestations and a long-term commitment is made. We were able to eradicate P. australis from approximately 35% of treatment sites and our success is likely to increase substantially (to approx. 72%) if sites where the species is currently absent for 1–2 years are deemed eradicated in the future. This success was achieved with a financial investment of <$100,000. SCIENCEBLOG 04/06/09 Changing climate may make ’super weed’ even more powerful. 11:07 a.m., June 3, 2009----Researchers at the University of Delaware have discovered a new reason why the tall, tasseled reed Phragmites australis is one of the most invasive plants in the United States.

The UD research team found that Phragmites delivers a one-two chemical knock-out punch to snuff out its victims, and the poison becomes even more toxic in the presence of the sun's ultraviolet rays. The study, which is published in the June issue of the scientific journal Plant Signaling & Behavior, is believed to be the first to report the effects of UV-B radiation on plant allelopathy, the production of toxins by a plant to ward off encroachment by neighboring plants. The authors include Thimmaraju Rudrappa, a former postdoctoral researcher at UD who is now a research scientist at the DuPont Company; Harsh Bais, assistant professor of plant and soil sciences; Yong Seok Choi, postdoctoral researcher in the Department of Chemical Engineering; Delphis Levia and David R.

Roseau commun

Pour les articles homonymes, voir Sagne. Elle est présente naturellement ou introduite en Asie, en Europe, en Amérique, en Afrique et en Australie. Elle a une tendance à devenir envahissante. Dans la province de Québec, au Canada, cette plante exotique est très présente dans les ruisseaux aux abords des routes et elle a envahi de telle sorte que les quenouilles (Typha) ont perdu leur domination dans ces ruisseaux, tout autour de Montréal du moins. Description[modifier | modifier le code] Cette graminée a de longues tiges fines ornées d'un plumeau argenté et peut mesurer jusqu'à 3 m de haut. C'est une plante aquatique qui doit avoir sa racine dans l'eau.

UNIVERSITY OF DELAWARE 23/12/09 Phragmites partners with microbes to plot native plants' demise. 10:47 a.m., Dec. 23, 2009----University of Delaware researchers have uncovered a novel means of conquest employed by the common reed, Phragmites australis, which ranks as one of the world's most invasive plants.

UNIVERSITY OF DELAWARE 23/12/09 Phragmites partners with microbes to plot native plants' demise

The invasive strain, which hails from Eurasia, overtakes its “native” cousin, which has lived in North America for the past 10,000 years, ironically by provoking the native plant to “take itself out,” through a combination of microbial and enzymatic activity in the soil. The research by an interdisciplinary UD team led by Harsh Bais, assistant professor of plant and soil sciences, is reported in the December issue of the scientific journal Plant Physiology and also is highlighted in one of the journal's editorials. In previous research, a team led by Bais determined that Phragmites employs a strategy known as allelopathy, in which plants release toxic chemicals into the soil to deter other plants from growing close to them. “Now we have a way to remedy the sick soil,” Bais said.

The Penn State Vegetation Management Project was initiated in 1985 to assist the Pennsylvania Department of Transportation's Bureau of Maintenance and Operations in the ongoing development of its roadside vegetation management program.

The original focus was on the evaluation of materials and methods for selective brush control, Canada thistle management in crownvetch, and growth regulation of roadside tall fescue turf; and to serve as an unbiased information source for the evaluation of emerging vegetation management technologies. Through continued funding from PennDOT, the project focus expanded to include all aspects of roadside vegetation management, using an Integrated Pest Management, or more specifically, Integrated Vegetation Management approach.

The aim is to preserve as much desirable vegetation as possible while minimizing undesirable vegetation and maintaining a desirable aesthetic, within the confines of limited resources.

Les espèces envahissantes représentent une menace sérieuse pour la biodiversité, la santé humaine et l'économie. Pour affronter le problème, des bases de données sur les espèces végétales et animales envahissantes constituent un besoin urgent au Canada et dans le monde entier.
