(2001) also stressed that some level of training and logistical support is required to implement such a management programme and identified key difficulties such as the lack of awareness of the problems that could occur if the weed is not effectively controlled, and discontinuity in control.

Their recommended strategy for controlling M. pigra is to prevent initial invasion, eradicate small infestations by physical or chemical means and, for large infestations, to adopt an integrated approach involving biological control, herbicide application, mechanical removal, fire and pasture management. Reproduction is by seed and vegetatively from cut stems. The pods are borne in clusters (of 1-30), are straight or slightly curved, and are initially green in colour. The larvae develop on the roots while the adults feed on the leaves. Global register of Introduced and Invasive species (GRIIS), Mimosa pigra var. Plant Production Quarterly.
