I want to conduct one experiment on Habitat management using a push-pull strategy. This involves intercropping maize with a “push” plant, such as Desmodium, that repels FAW from the field, and planting a crop along the field boundary (e.g. Napier grass or Brachiaria spp) that attracts or “pulls” the FAW away from the maize. So i want to know the where i will get the Desmodium and Napier grass seeds.
