Oil palm is a plantation crop that produces palm oil and palm kernel oil which are Indonesia's main source of foreign exchange from the plantation sector. The practice of monoculture cultivation on oil palm plantations grown on various types of soil in Indonesia, has big challenges in the aspect of cultivation, especially pest and disease control. One of the diseases that cause losses in the cultivation of this commodity is dry frond. This disease has been found in oil palm trees in the plantation of PT Bumitama Gunajaya Agro grown on Quartzpsamments and Haplohemists soils. This pathogen causes the rachis and leaves to dry from the tip to the base of the frond. The spread of this disease is thought to be due to contact between infected to healthy fronds. In this study, 6 isolates were obtain from leaves and 7 isolates from infected rachis. Based on the macroscopic and microscopic characteristics of the isolates, one isolate from Sungai Langir Estate belonged to the genus Thielaviopsis sp. However, the postulate koch test showed that the thirteen isolates could not infect and cause symptoms of dry frond disease on the leaves and rachis of the tested oil palm plants.
