Effects of treating creosotebush with tebuthiuron on rodents

by: William G. Standley and Norman S. Smith
ABSTRACT: Three years after creosotebush (Larrea tridentata) was treated with tebuthiuron, rodent abundance was 71% higher on treated plots than on control plots in southeastern Arizona. Arizona cotton rats (Sigmodon arizonae) and western harvest mice (Reithrodontomys megalotis) were more abundant while the abundance of Merriam's kangaroo rats (Dipodomys merriami) was similar. We conclude that tebuthiuron may be safely used to control creosotebush in semidesert grasslands unless the presence of rare or endangered species precludes any alterations to the community.
