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]
