Several selective grass herbicides were tested for efficacy in controlling brome grass (Bromus pectinatus Thunb.) in barley crops over a six year test duration. Only one herbicide, Avadex BW EC, showed a generally acceptable level of performance under the various test conditions. Several factors contributed to this level of performance. The results showed that brome grass exerted a severe competition with the barley crop, which is vulnerable at the early growth stages due to poor root development. Early control of brome grass in barley resulted in a significant barley grain response. The grain was superior in nitrogen content and had an increased proportion of large grains. Successful control of brome grass requires a properly planned, long-term control strategy based on a thorough knowledge of brome biology
