Abstract
This study was conducted at five previously treated semiarid rangeland locations in northcentral Arizona to determine how long tebuthiuron remains in the soil and to what depths it penetrates into the soil. Treatments were made from 1975 through 1979. Soils were collected from 1980 through 1986 at 0- to 7-cm, 7- to 15-cm, and successive 15-cm layers to bedrock or into caliche layers from the perimeter of 3- by 0.5-m trenches dug perpendicular to the long axis of the plots. Tebuthiuron was assayed using gas chromatography with flame photometric detection
