Desmodium intortum, known as greenleaf desmodium and also as beggarlice along with other members of its genus, is a species of flowering plant in the genus Desmodium, native to Mexico, Central America, northern South America, the Galápagos, Haiti and Jamaica. A nitrogen-fixing fodder crop, it has been introduced to the rest of the world's tropics, including Africa, India, Australia, New Guinea and Taiwan[2]

Desmodium intortum is used in push–pull agricultural pest management since it contains potent secondary metabolites that are released into the soil and aerially. Inter-cropped in maize and sorghum fields, it repels Chilo partellus, a stem-boring grass moth, and suppresses witchweeds, including Asiatic witchweed (Striga asiatica) and purple witchweed (S. hermonthica).[3]
