New Fact Sheets Added for Invasive Plants and Weeds
The Renz lab in the UW-Madison Agronomy Department in cooperation with University of Wisconsin-Extension Team Horticulture, Wisconsin Department of Natural Resources, and the Midwest Invasive Plant Network has continued the development of a series of fact sheets on invasive plants and urban weeds that was started in 2009. This series summarizes important identifying characteristics for each featured species, as well as information necessary for developing a management plan. The bulk of each sheet lays out non-chemical and chemical control methods. Information highlighted includes timing of treatment for each technique, effectiveness of treatments, and remarks and cautions particular to each technique. The products or techniques included are in common use or are known to provide effective control as documented by researchers and land managers. Those products and techniques that do not provide sufficient control or lack information for effectiveness on target species have been omitted. It is our hope that these sheets will provide everyone with the information needed to manage invasive species in their specific situation.
We are releasing 18 new sheets, representing 23 species. This brings the series to a total of 33 sheets and 44 species. You might have seen the original batch of species, but with this new release we have updated all of our sheets to include new herbicide products and a rating system that allows the user to compare the effectiveness of control techniques. The control information is given as a percentage of the original infestation that is controlled the year of the application and the year after the initial application with no subsequent application of control.
All of the sheets are available at the UW-Extension Weed Science web site (http://fyi.uwex.edu/weedsci/) or you can follow the links below directly to a species.
