Abstract

Sweet potato (Ipomoea batatas L.) is one of the important crops that were infected by many pests. One of these pests is two spotted spider mites (Tetranychus urticae), which is considered a serious pest that caused a high reduction to the infested crop causing a loss in quantity and quality of the yield. So, in this study, there was one peak on the leaves of sweet potato plants, which was on 7 August during the two years 2021/ 2022. However, Areka (abamectin) is the most effective tested insecticide reported 97.78 and 100% for 2021 and 2022 but Clinser (Pyridaben) recorded 89.82 and 96.67, respectively.
