ABSTRACT

Cadamba (Anthocephalus cadamba Miq). is an alternative tree species for raw pulp and paper material. As homogeny ecosystem, cadamba plantation has many problems in pests and diseases attack. The aim of this research was to identify and evaluate the severity level that caused many pest and diseases attacking cadamba. Average incidence percentage of pest attack at CF pantai cermin showed the highest pests attacking cadamba plantation is A. hilaralis (31%) and C. sumatranus (16.4%). While at IPF Baserah, A. hilaralis (73%) and C. sumatranus (13.2%) became the dominant species. Further while A. hilaralis (18.65%) and Coptotermes sp. (6.3%) became two dominant species at IPF Pelalawan. The defoliator damage showing the highest level was happened at HTI Baserah sector (92.88%) and the lowest was happened at HTI Pelalawan sector (40.5%). The diseases observation showed that leaf spot that was caused by Cercospora sp., Pestalotia sp., Curvularia sp. and Colletotricum sp. had highest attack percentage in 4 location (98%-
100%), second dominant diseases were black mildew that were caused by Meliola sp. (2.3%-6%), third dominant diseases were stem and root rot that were caused by Fomes sp., Schizophyllum sp., Pleurotus sp. and Auricularia sp. (3%-6.8%), and the fourth dominant diseases were stem cancer (0,4%) that caused by Corticium salmonicolor and Lasiodiplodia sp. The highest severity level caused by leaf spot showed highest level at industrial plantation forest of Pelalawan sector (96.88%), industrial plantation forest of Baserah sector (90.88%), Pantai cermin community forest (64.45%) and Rumbai community forest (65.37%).
