Incidence and severity of leafspot and leaf rust were investigated on Fonio during growing season of 2022 and 2023 in four fonio growing ecologies. Twelve promising pure lines of D. iburua and a popular accession from each locality were involved. The design of the experiment was RCBD, having three replications. IBPL05-19-03 and IBPL04-06-04 showed no symptoms of leaf spot in all the plots. Significant differences at all the locations were observed for the genotypes. Highest score of incidence was recorded by the IBPL04-18-05 scoring 31% to 50% at Kabo and Ganawuri respectively. Consequently, the severity score indicated that the genotypes were either resistance, moderately resistance or tolerance for both leaf spot and leaf rust diseases across the locations. Furthermore, a more detailed, wide area survey and the use of modern disease diagnosis methods are recommended for fonio in all growing ecologies in the country
