Description
Bromus diandrus and Bromus rigidus are internationally distributed weeds, particularly common in rain-fed, dryland cereal cropping regions in Mediterranean climates. The taxonomic structure within the Bromus genus is unclear, and it is not apparent if B. diandrus and B. rigidus are one species or two. These weeds have become increasingly prevalent following the introduction of conservation tillage. They are not easily controlled by the limited range of available herbicides, partly due to ecological factors including variable dormancy, staggered emergence, and highly competitive growth. There is also varying herbicide efficiency due to initial weed density and environmental conditions. Integrated weed management programs are necessary to control these species, and populations can be eradicated in 3–4 years. However, the problem remains that control measures quickly become too expensive to be practical in the non-irrigated, low yielding cropping regions where these grass weeds are most apparent.
