Agarwood (Aquilaria malaccencis) Health at Nursery

Abstract

Gaharu (Aquilaria malaccencis) is a tree species included in Thymelleaceae family, Agarwood can grow in lowland as well as mountains, up to 750 m above sea level.

This plant produces a resin powder which has a distinctive aroma fragrance infected due to fungal diseases (fungi) that enter through the trunk wound. The objective of this study is to identify the characteristics of attack which causes damage to the agarwood plant seedlings (Aquilaria malaccencis) and to elucidate the intensity of pests and diseases on agarwood plant seedling (Aquilaria malaccencis). By using code of Environmental Monitoring and Assessment Program (EMAP) which had been modified so that it was obtained the damage cause, damaged parts of plants, the type and the level of severity of damage suffered by the plant. Based on the results, data showed that the biggest cause of the damage suffered by the agarwood plant was a disease characterized by symptoms on the leaves where the damage type was in the form of leaf discoloration with the level of severity of 20-29%. The intensity of damage was 44. 66%, damage due to pest was 8%, and damage due to illness was 32%.
