Identification:
Annual; foliage deep blue-green. Tends to lie flat prior to seed formation. Spikelets awned, the longest awns at the top of the spike. Seed heads break into individual segments at maturity.
Impacts: Jointed goatgrass grows best in cultivated fields, but it can also invade grasslands. It thrives in wheat fields, rangelands, roadsides, and fencerows. Ten jointed goatgrass plants per square yard can reduce cereal crop yields by 30 to 50%. Jointed goatgrass seed is a contaminant in cereal grain seed crops where it alters their milling characteristics and reducing the value of the grain.
Biological
Controls: No approved biological control agent is available.
