What is Biological Control and how can it help in the management of noxious weeds?
Biological Control is the introduction of a known predator on a pest for management. Known, natural predators, will feed on the reproductive parts of the plant, defoliate them, and interfere with their ability to transport nutrients. As a result, the plant population will be suppressed and reduced over time.
How long does biocontrol take to be effective?
Biological Control can take anywhere from 5 to 30 years to be effective. Environmental variation can enhance or inhibit the success of biocontrol. Patience, biological control monitoring, and multiple biological control releases may be necessary.
