Abstract:
Aquilaria malaccensis Lamk. (Locally known as Sasi or agar plant) is a precious floral wealth of North-East India and has been identified as a potential aromatic plant of this region. It is the principal producer of the dark brown agarwood or eaglewood, produced within heartwood as a result of host-fungus interaction. The essential oil from agarwood is valued for preparation of several pharmaceutical and cosmetic products. Due to the abundance of agar trees in North East India, the trade of agar has become a fascinating industry in this region and earned a name of its own in the world market. During the survey in the nursery of Rain Forest Research Institute, Jorhat Aquilaria malaccensis seedlings were found to be infected with a leaf spot disease. This study described the symptomatology and etiology of the disease. The pathogenicity studies revealed the cause of the disease as Corynespora cassiicola (Bark and Curt). This disease is recorded for the first time in Aquilaria malaccensis.
