Biological Weed Control

 

Biological weed control is a long-term management technique that involves releasing natural enemies to control non-native species.  Usually insects are imported from continents where the weeds originated. Inspect predators must be carefully tested to be sure they eat only a specific weed and are safe to release in North America.

 

The most successful method of weed control is an Integrated Pest Management (IPM) approach. IPM consists of using herbicides, biological weed control agents, grazing, mowing and other mechanical methods. 

 

Acquiring Biological Control Insects

In Montana, several biological control agents have been successfully to reduce infestations of noxious weeds such as leafy spurge and spotted knapweed.  County weed coordinators can provide information on using biological control methods, and may be able to provide information on insect collection sites or contact information for private businesses selling insects. See the links below for more information on biocontrols.
