AbstractCommon broomweed (Amphiachyris dracunculoides) infests Texas rangelands during the fall, winter, or spring in years with abundant soil water. Herbicidal control of common broomweed was studied in the Rolling Plains of Texas in 1977, a wet year. Dicamba and picloram plus 2,4,5-T effectively controiled broomweed at rates ranging from 0.14 to 1.1 kg a.i./ha. Tebuthiuron produced less consistent control and 2,4-D was ineffective at rates from 0.14 to 1.1 kg/ha. Broomweed production was reduced and grass production increased regardless of whether dicamba or picloram plus 2,4,5-T were applied in early December, late January, or mid-May. Grass production increased 1.5 fold following broomweed control. Compared to untreated plots, neither soil water content nor soil temperature were affected by broomweed reduction, but photosynthetic active radiation reaching more desirable forage was significantly increased by broomweed control.
