Noviani., Pratama, R., Dzulkifli., Ahda, N., & Makkiah, Q.A.Cylindrocladium sp. is a pathogen that causes disease in nurseries and affects Eucalyptus leaves from young to mature stages. This disease inhibits photosynthesis, thereby reducing plant productivity. The objective of this study was to determine the symptoms, incidence, and severity of the disease on Eucalyptus plants in Baung Central Nursery and Sungai Beyuku Nursery. The research method involved direct field observations and sampling of plants infected by Cylindrocladium sp. using purposive sampling at Baung Central Nursery of PT Bumi Andalas Permai (BAP) and Sungai Beyuku Nursery of Bumi Mekar Hijau (BMH). The results showed that the frequency and severity of leaf blight and stem rot were highest in Sungai Beyuku Nursery. Leaf blight and stem rot caused by Cylindrocladium sp. exhibited the highest incidence and severity in Sungai Beyuku Nursery, with leaf blight incidence reaching 30.72% and severity 25.85%, whereas Baung Central Nursery recorded a leaf blight incidence of 18.56% and severity of 21.04%.
