How Do You Spell DIGITARIA ISCHAEMUM?

1. Digitaria ischaemum, commonly known as smooth crabgrass, is a warm-season grass species belonging to the Poaceae family. It is an annual weed often found in lawns, gardens, and other disturbed areas.

   Smooth crabgrass typically forms a dense and spreading mat with wiry stems that can reach up to 15-60 cm in height. Its stems are smooth, flattened, and can root at the nodes which allow it to spread and colonize new areas rapidly. The leaves are light green to bluish-green, narrow, and have a prominent midvein. They are arranged opposite each other on the stems, often appearing in a folded position.

   This grass species produces a dense inflorescence, known as a panicle, which is composed of numerous spikes. Each spike can bear up to 11 spikelets, each of which contains one flower. The flowers are small and wind-pollinated.

   Digitaria ischaemum has a notorious reputation as a weed due to its aggressive growth and ability to survive in a wide range of environmental conditions. It thrives in areas with full sun exposure and is highly adaptable to various soil types. Smooth crabgrass is known for outcompeting desired turfgrass species, leading to its classification as a noxious weed in many regions.

   Efficient management of Digitaria ischaemum often includes prevention of seed germination through regular lawn maintenance practices such as proper mowing height, adequate watering, and soil fertility management. Control measures may also include the use of selective herbicides or manual removal if the infestation is limited.
