Noxious & Invasive Weed Control

A noxious weed is an invasive plant defined and governed by law as being particularly troublesome, undesirable and difficult to control.  Typically, they are plants that grow aggressively, multiply quickly and compete with pasture and/or crops reducing yields substantially.  In addition, noxious weeds modify habitat structure.  This threatens biodiversity and ecosystem stability.  Noxious weeds can also be poisonous or cause injury to humans, livestock and wildlife.  They compete with resources that desirable plants need, for example: water, soil nutrients and sunlight.  They are extremely high in water consumption. 


There are other weeds that are not listed as noxious which are invasive; however, they can spread and take over an area of land (Field bindweed, ragweed, dock, horseweed, and bull thistle to list a few).  These weeds deprive the grass of much needed moisture. 


Zone45’s objective is to manage an area to raise as much grass possible.

We use an integrated weed management program to control noxious and invasive weeds through a long-term management approach.
