Biological Weed Control

 

Biological weed control is a long-term management technique that involves releasing natural enemies to control non-native species.  Typically, insects are imported from continents where the noxious weeds originated.  Insect predators are carefully tested to be sure they only attack 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 used to reduce infestations of noxious weeds such as leafy spurge and spotted knapweed.  County weed coordinators can provide information on implementing biological control methods, and acquiring insects.  See the links below for more information.
