Saccharum officinarum
Striga hermonthica, commonly known as purple witchweed or giant witchweed, is a hemiparasitic plant that belongs to the family Orobanchaceae. It is devastating to major crops such as sorghum ("Sorghum bicolor") and rice ("Oryza sativa"). In sub-Saharan Africa, apart from sorghum and rice, it also infests maize ("Zea mays"), pearl millet ("Pennisetum glaucum"), and sugar cane ("Saccharum officinarum").
