Within the past decade interest in the control of undesirable woody plants on grazing lands of southwestern United States, and Central and South America has grown by leaps and bounds. Development of new herbicides, adaptations of mechanical equipment, and improved techniques of establishing more productive strains and species of grasses all have stimulated grassland improvement. The driving force back of these new developments has been three pronged: (1) the demand for more efficient and economical production of meat, milk and wool; (2) the realization that early methods of coping with brush were inadequate and too costly, and (3) the gradual shift from the production of surplus crops to grassland farming. This paper reports on methods that have been developed for the control of three major undesirable woody shrubs on rangelands in the southwestern part of United States, in Cuba, and in Brazil. These species include mesquite (Prosopis juliflora) in the United States, marabu (DG chstachys nutans) in Cuba, and leiteiro (Taberae montanu fuchsiuefoliu) in Brazil.
