The Nez Perce Bio Control Center provides a full service biological weed control program to landowners and managers throughout the state of Idaho and the Pacific Northwest.
Biological control is the intentional use of a living organism to reduce the population of an undesirable pest. The types of biological agents used to control noxious weeds include: Insects, Diseases and Vertebrates, such as goats, sheep and cows.
Biological control agents are selected for their ability to affect different parts of the weed; the flowers, leaves, stems and roots. The most effective biological control programs use a mix of agents, attacking many parts of the weed, to reduce the competitive advantage they have over native species.
Biological controls, by themselves, will not completely eradicate a weed population. They must be combined with other integrated weed management techniques to be successful. Properly tested and approved biological control agents will feed only on their targeted weed. They will not move to, or feed on, any other plant.

To keep weeds off your land - keep your lands healthy. Maintaining a healthy ecosystem should be the primary objective to keep invaders out. Mechanical methods, such as pulling, should be your first approach. While herbicides work in most circumstances, biological methods should be considered. So how do you know what control method is better to manage the weeds on your lands?
Just click on the name of a weed you want more information on. You will then be given the best control methods available to manage that weed and links to other sources for more education and information.
