Crow corn, which refers to a type of weed known as Sorghum halepense or Johnson grass, is often found in fields as it can be harmful to crops. There are a few different synonyms for this weed, including tall sorghum, Aleppo grass, Sudan grass, and elephant grass. While it is sometimes used as a forage crop for livestock, in most cases, crow corn is considered a nuisance by many farmers and gardeners for its tendency to spread rapidly and overtake agricultural fields. Effective weed control methods can help eliminate this persistent and invasive plant and preserve the health of crops.
