In Uganda, as in many other countries of sub-Saharan Africa, groundnut rosette is widespread, and especially destructive on late planted crops. Rosette is a virus disease spread by aphid vectors Aphis craccivora Koch. To reduce losses due to this disease, scientists in Uganda have developed the cultivar ‘Igola-1″; it is resistant to rosette and high yielding. Other technologies related to the control of the disease such as use of high plant density, timely planting and insecticide sprays are also available, and except for insecticide sprays, others are largely unknown to farmers. Through farmer-participatory research, this project mounted on-farm trials to expose farmers to these technologies have been mounted.
