The degradation of pastures is a process characterized by the invasion of undesirable species and the loss of productivity with the consequent decrease in animal carrying capacity. The objective of the research was to reduce the coverage of Austrocylindropuntia floccosa, through controlled burning, chemical control, and the integration of these two methods. The study comprised three trials. The first, evaluated the invasion dynamics of undesirable plants, the second, measured the effect of three methods of control, burning, chemical and the integration of both in comparison with a control, and the third realizing an economic evaluation, based on modelling the carrying increases under a 20-year planning horizon. The results showed alterations in the structure of the vegetation: a increase of plant cover of undesirable plants, a decrease in the frequency of grasses, herbaceous plants, forage index, basal plant cover, mulch and pasture condition , and a increase in the presence of shrubs, erosion pavement and bare soil Significant differences ( p < 0.05) were observed in mortality of A. floccosa between burning, chemical control and integrated treatments in relation to control regardless of topographic position. The control of undesirable’s plants, increased the carrying capacity (UO/ha/year) in 0.14 UO for the control, 0.43 UO for the burning, 2.61 for the chemical and 5.39 UO for the integrated control. The economic analysis determined net income (NI), net present value (NPV internal rate of return (IRR) and capital recovery time (KRT) of: control, US$ 5.10, US$ -349.87, -10%, 76.45 years; burning, US$ 15.37, US$ -296.77, -3% and 27.27 years; chemical control, 92.38, US$ 308.46, 20% and 4.87 years and integrated control US$. 190.36, US$. 1058.02, 42% and 2.41 years, respectively. It is concluded that the invasion of A. floccosa alters the dynamics of the vegetation and that the most effective method of control, from a bio economic perspective, is the integrated control.
