Biological Control

Biological control of weeds is the use of one organism to control another. Classical biological control is the introduction of control agents – usually insects – into a region that is not part of their natural range, to permanently reduce the populations of selected weeds usually also introduced into the region. REDUCE, not GET RID OF!
