Track 3-3-1: Sustainable Use of Tropical vis‐a‐vis Temperate Grasslands
Description
Chirahui (Acacia cochliacantha) is an aggressive tall-shrub which invades buffelgrass (Cenchrus ciliaris L.) in the short jungle area of Southern Sonora, Mexico. As brush invasion takes over the pastures buffelgrass forage production declines and spiny brush species interferes with cattle grazing (Martin et al., 1995). Manual brush control practices are common in the area but are normally ineffective because plants re-sprout back and reinvade pastures. Tordon 101 herbicide (64.0 g a.i./l Picloram + 240.0 g a.i/l 2,4-D) has been widely used for brush control in northern Mexico but it is expensive and is planned to go out of the market soon. Prado herbicide (621.3 g a.i./kg. Amynopyralid + 94.5 g a.i./kg. Metsulfuron metil) is a new and economic product released from Dow Agrosciences in Mexico but no local data is available for its use. This study was conducted in summer of 2011 to evaluate the efficiency of Prado herbicide and manual control by machete to reduce chirahui populations.
