RENTABILIDAD DEL HERBICIDA PASTAR® EN EL CONTROL QUÍMICO DE ARBUSTOS EN PRADERAS DE ZACATE BUFFEL EN LA REGIÓN CENTRAL DE SONORA, MÉXICO

The study was carried out in 2008 in 3 locations to evaluate the efficiency of Pastar® herbicide in the control of chirahui, vinorama and mezquitillo in buffel grass prairies at central Sonora.

The herbicide was applied to the foliage to plants 1.6 m high. Changes in vegetation during 2008, 2009, 2012 and 2015 were evaluated and financial runs were carried out to determine the profitability of shrub control.
