When Does a Weed Become “Super”?

The term “superweed” has come to mean any weed that has become difficult to manage even if there has only been one or two management techniques employed. However, according to the Weed Science Society of America, this isn’t what a true superweed is. Just because a weed has developed resistance to one management technique (such as how dandelions begin to produce seed differently in a regularly mowed lawn), does not make it “super”. A true super weed has the ability to develop resistance to all kinds of management techniques, including multiple herbicides and mechanical, biological, or cultural management techniques. This new definition of superweed is hoped to clear up any confusion and encourage proper weed management techniques. More information about what a superweed really is can be found here.
