Creosotebush (Lurrea tridrntato [Sesse & Moe. ex DC.] Cov) 8nd other shrubs have spre8d into semidesert gmssl8nds of the southwestern United States urd northern Mexico; and 8s creosotebush increases, perennial gmssea decre8se. This study evalu8ted 3 rates of tebuthiuron 8nd 4 mechanierl treitments in 1981 and 1982 for creosotebush coqtrol at 4 locations, 3 in Chihuahu8, Mexico, and 1 in Arizona, U.S.A., md compared forage production 8fter treatment with untreated checks. Creosotebush mort8lities 8veraged across ioc8tions 8nd ye8rs were 75,87,93,3,33,68, and 66 for the 0.5,1.0, and 1.5 kg ri/hr tebuthiuron (N-(5-(l,l-dimethylethyl)-1,3,4-thi8dlazol-2-yl~N,N’-dhnethylurea), l8nd lmprinting, 2-way r8iling, disk plowing, 8nd disk plowing with contour furrowing treatments, respectively. Forage production averaged across locations and years was 529,524,606,303,344,290,330, 8nd 302 kg/ha for the 0.5,1.0, nnd 1.5 kg rijhr tebuthiuron, land imprinting, 2-W8y railing, disk plowing, disk plowing with furrowing, and untreated check tre8tments, respectively. Precipitation ~8s below long--term me8ns at rli Chihuahuan lo&ions in 1983, and forage production was significantly greater on most treated plots where brush was controlled thrn on untre8ted checks. At the Arizon8 location precipit8tion ~8s above the long-term meln in 1983 8nd ail plots treated in 1981, except the disk plowing 8nd disk plowing with furrowing which destroyed perennirl gnsses, produced signific8ntly more grass for8ge than the untreated checks. Precipitation was 8bove the long-term me8ns rt all loc8tions in 1984 and about hrlfof the plots tre8ted with tebuthiuron produced significantly more forage than the untre8ted checks but not any mechanic8lly treated plots. When treatments reduced shrub density and remnants of native forage grasses were present, forage production increased in both wet and dry years.
