Sweetpotato production in Tanzania is hampered by high virus incidences. These viruses exercise synergistic interactions leading to up to 98% yield losses. Further, this makes their control difficult. It is therefore important to equip farmers with simple and affordable technologies which they can use to manage the spread of SPVD such as insect proof net tunnels.This poster presents a study on parameters that affect the technical feasibility of net tunnels. The main observation from the study was that the net tunnel technology could be cascaded down to farmer-multipliers successfully provided there is proper management.
