Methods of reducing ripgut brome seed production and carcass damage

Abstract

Ripgut brome (Bromus diandrus) is an annual grass weed prevalent in dry, hill and high country regions throughout the South Island. Its large seeds contaminate wool and carcasses. Two studies were undertaken in 2006/2007 to test strategies to control and mitigate its impacts. The first study (South Canterbury) tested different rates and timing of application of herbicides on ripgut brome.
