"T. compactum" is similar enough to common wheat ("T. aestivum") that it is often considered a subspecies, "T. aestivum compactum". It can be distinguished by its more compact ear due to shorter rachis segments, giving it its common name.

Crop weeds can inhibit the growth of crops, contaminate harvested crops and often spread rapidly. They can also host crop pests such as aphids, fungal rots and viruses. Cost increases and yield losses occur as a result. Striga, one of the main cereal crop weeds in Sub-Saharan Africa, commonly causes yield losses
