A Risk assessment of Mimosa pudica for Florida was prepared by Gordon et al 2008. The result is a score of 17 and a recommendation of rejection for import into Florida.
Physical: Hand weeding is difficult due to the presence of thorns and a woody root (Wagner, 1983; in PIER, 2005). Repeated burning may in fact encourage the spread of M. pudica in pastures (Magda et al., 2006).
Chemical: It is susceptible to several herbicides, including dicamba, glyphosate, picloram and triclopyr (Parsons and Cuthbertson, 1992). Very sensitive to picloram (0.25 lb/acre), sensitive to triclopyr. Dicamba and 2,4-D poor. Soil applied tebuthiuron effective (Motooka et al., 2002) (all from PIER, 2005).
In pasture situations, dicamba and fluroxypyr can be used to control M. pudica. Thorough wetting of all leaf surfaces is essential. If plants are disturbed before spraying, the leaves will fold up and the herbicide will be ineffective. Ensure all spraying is done with forward booms or ahead of operators with knapsack sprayers (Land Protection, 2006).
Biological: See Waterhouse and Norris (1987) and Waterhouse (1994) for information on prospective biological control agents (PIER, 2005).
Coir dust, a waste from coconut processing, can be used as a mulch in pineapple crops to suppress M. pudica and other weeds (Van Mele et al., 1996).
Sheep grazing is reported to control the dominance of M. pudica in pasture (Magda et al., 2006; Francis, undated).
