Disease incidence and disease severity were evaluated to determine the prevalence of Taro Leaf Blight in Iwollo. Four cocoyam (Colocasia esculenta L. Schott) farms from each of the six villages in Iwollo namely, Umueze-Onyia, Ndibunagu, Amagu, Obinagu, Owolloti and Enugwu were randomly selected and a farm area of 8m × 4m (32 sq m) marked out in each of the farms for the experiment. The experiment was laid out in completely randomized design (CRD) comprising six treatments with four replications. Number of plants infected with taro leaf blight was counted and the area of the affected leaves measured and used to evaluate the disease incidence and disease severity. Data collected were subjected to Analysis of Variance (ANOVA) for completely randomized design and the means showing significant difference compared using least significant difference (LSD) at 0.05 probability levels. The results revealed significant differences (p<0.05) in disease incidence and disease severity among the villages in Iwollo. All the villages recorded high incidence and severity of Taro Leaf Blight with the highest percentage obtained in Umueze-Onyia village. It could be concluded from the results that there was high prevalence of Taro leaf blight in Iwollo. Good management strategies are therefore required to control Taro leaf blight and improve cocoyam production in the area.
