Control of Sand Shinnery Oak (Quercus havardii) with Pelleted Picloram and Tebuthiuron

  • Pete W. Jacoby (a1) and Cecil H. Meadors (a1)

Abstract

Sand shinnery oak (Quercus havardii Rydb.) was controlled by both picloram (4-amino-3,5,6-trichloropicolinic acid) and tebuthiuron (N-[5-(1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl]-N,N′-dimethylurea} in the Rolling Plains vegetational region of Texas. Tebuthiuron provided acceptable control of sand shinnery oak at rates of 0.6 to 1.1 kg/ha, but 2.2 kg/ha of picloram was required to give comparable results. Tebuthiuron pellets applied at 0.6 kg/ha controlled 79% of the sand shinnery oak within 30 to 67 months after application. Applied at 1.1 kg/ha, tebuthiuron controlled 91% (average for three locations). No differences were found between formulations of a given herbicide.
