Gaharu Inoculation Service

Wounding Agarwood and Method of Induction

The expensive agarwood is produced by the trees from Aquilaria species. The tree itself has no special value. However, the resin created when the tree is either physically wounded by animals and fire or populated by insects or fungi is widely used for its medical and aromatic properties.

Only a small percentage of Aquilaria trees produce the desired resin. Meanwhile, the natural Agarwood is more expensive than diamonds. That’s why there are several artificial ways to force the tree to produce the material required to create the valuable Agarwood oil.

C & L Gaharu Inoculation Service

specialized in Inoculation of Gaharu Trees (agarwood) for years with guaranteed result in three months

Fungal inoculation is a new and improved wounding method that takes much less time to produce the results. It also involves drilling holes in a tree, but their size is much smaller than when the traditional wounding is done.

Special spots are chosen to injure the trunk in order to provide space for air circulation. The holes themselves are not more than 10 cm deep. About 50 – 100 holes are drilled in the trunk of a tree about 5 – 7 cm away from each other. Then some pipes made out of plastic or natural materials are inserted to keep the holes open and provide proper aeration. The aeration technique is used for many different inoculation methods.

Fungi is injected into the holes in order to stimulate natural resin production. The best results can be reached by using the fungi collected from another Agarwood tree.
