Abstract

This study aimed to determine the symptoms and signs of diseases on the shoot, stem, root, the causal agent, and the disease’s incidence and severity. The most resistant families and the most detrimental pathogen were also discussed. The study was conducted at Surya Hutani Jaya Concession, Sebulu in Kutai Regency, East Kalimantan Province, and continued to identify the pathogen in the Laboratory of Forest Protection, Faculty of Forestry, University of Mulawarman. The study’s object was E. pellita progeny test of 6 years old, with a spacing of 3 m × 2 m, and at the nursery. The seed was originated from the clone of Riau (Sumatera). The study revealed that there was a dieback disease caused by Botryosphaeria sp., stem canker by Coryneum sp., root rot by Ganoderma sp. and termite Coptotermes sp. at the plantation, while at the nursery was found damping-off caused by Fusarium sp., leaf feeders of locust Atractomorpha crenulata and leaf roller caused by caterpillar Strepsicrates sp. The incidence of dieback disease at plantation ranged from 79.2% to 6.3%, stem canker was only one tree (47.9%), root rot was also only one tree (46.8%), and termite attack ranged from 70.8% to 39.6%. The severity of dieback disease at plantation ranged from 22.2% to 4.2%, stem canker 1.4%, root rot 2.8%, and termite attack ranged from 4.2% to 1.4%.
