I have received calls requesting information on how to manage or control unwanted growth of brush and small trees. Various invasive species such as buckthorn and autumn olive are very aggressive and will take over a woody area and crowd out other native species of trees.
Due to a barrage of advertising the control most people think of is the use of glyphosate. Glyphosate was originally sold under the brand name of Round-Up and now is sold under a number of brand names, and is a non-selective herbicide that will definitely kill brush and trees.
One of the drawbacks with using this herbicide is that being non-selective it will kill everything it comes in contact with. This means it will kill off any grass or other ground cover as well as the intended weed or brush it is applied to.
There are a number of other options available to the commercial producer or the small homeowner for controlling brush and hard to control weeds. The herbicide 2,4-D, is widely used for the control of broadleaf weeds such as dandelions. This herbicide by itself will not control hard to kill weeds such as creeping charlie or poison ivy nor will it control brushy weeds.
There are however a number of combinations of 2,4-D with other herbicides that will control these weeds. The benefit of using these herbicides over glyphosate is that the grass ground cover will remain alive and intact.
