Control of Mixed Brush with Tebuthiuron

Abstract

Tebuthiuron pellets, 10 or 20% active ingredient, aerially applied at 2.24 kg/ha active ingredient resulted in excellent control of whitebrush, spiny hackberry, and Berlandier wolfberry in South Texas mixed brush. At 2.24 to 3.36 kg/ha active ingredient, the herbicide appears promising for control of lotebush, blackbrush acacia, ceniza, Texas colubrina, javalinabrush, guajillo, guayacan, desert yaupon and twisted acacia. Rates of 3.36 to 4.48 kg/ha active ingredient, applied as tebuthiuron pellets, appeared promising on huisache but only partially controlled honey mesquite. Tebuthiuron was ineffective on lime pricklyash, Texas persimmon, pricklypear, and tasajillo.
