Aims: Passion fruit (Passiflora edulis Sims) is among the most important fruit crops in Kenya, which are produced for both local and export markets. In Uasin-Gishu County, passion fruit had recently emerged as an important cash crop for the small-holder farmers. Despite the impor...
Aims: Potato (Solanum tuberosum L.) production in Kenya has not been achieved in its full potential due to susceptibility of potato varieties to pest and diseases among others. Bacterial wilt, caused by Ralstonia solanacearum in potato is regarded as an important disease contribu...
