Broom Snakeweed Control with Tebuthiuron

Abstract

Broom snakeweed was effectively controlled for at least 3 years with 0.6 kg a.i./ha (80% wettable powder) tebuthiuron on the Southern High Plains. Total herbage production decreased following broom snakeweed control, but grass yield generally increased when the snakeweed was removed. Broom snakeweed control was not affected by application time during the year. However, grass production was significantly reduced for three growing seasons by application of tebuthiuron in May. Grass yield was not affected by applications in either November or January.
