Aegilops cylindrica (weed) Ces. - (jointed goatgrass)

This grass is native to Europe and western Asia. It is invasive in North America and was accidentally introduced there with contaminated wheat seeds in the 1880s. A. cylindrica has developed into a major weed of wheat in North America. It is actually closely related to wheat, making it possible that traits like herbicide resistance are exchanged between both species.

A number of research programs and projects have focused on the management of jointed goatgrass. Several improved cultural practices and crop rotations schemes have been develop, as have been imazamox-resistant wheat cultivars. The use of these techniques can reduce the infestation of jointed goatgrass by about 50% (see Mallory-Smith et al., 2018, also for a review of this weed).
