Torpedograss (Panicum repens
) is a warm season grass that is renowned for its extremely pointed tip. It is native to Africa and or Asia and has become a serious weed in warm climates. Torpedograss has hairs on the upper margins of the leaves and the surface is often covered with a waxy or whitish coating. The weed has a panicle type inflorescence, but depending on climate or location it can spread by rhizomes. In the southern United States it does not germinate well. It likes moist conditions and can grow up to 3m tall while tolerating flooding. It generally is considered to have fibrous roots and germinates most successfully when soil temperatures reach 20°C. It is sensitive to prolonged cold temperatures. Reducing moisture buildup through relieving compaction and ensuring infiltration rates of water are sufficient will aid in its control.
