Which inoculation technique is the best?

Hi everyone, after a long time not updated something regarding gaharu. Today, I would like to write something about inoculation inducement technique for those who question and interested to know. One of the question is:

Which is the best technique/method to maximise the production of gaharu in terms of the karas and for production of its oil(distillation process)?

In my opinion, the inoculation technolgy is much better compared to traditional method in term of time consuming, cost effective and high yield of production. But the second question come, which is the best inoculation technology?
A successful research on inoculation technique makes people extremely looking for the best technique that can produce high yield and the best quality of agarwood or chips for oil distillation. Everyone claims that they have the best technique. But until now, we still cannot summarize which technique or formulation is the best because of many factors such as countries where gaharu planted, species of gaharu used and apply to wild or planted trees.
In my opinion, we still in very infant stage to decide which technique are the best. Many people in this industry used “try and error” method to see the results. The proven scientific research already started but there’s still a long journey to go.
In our neighbor countries like Thailand, Vietnam and Laos, some of them used CA kits ( Cultivated Agarwood Kits) to produce agarwood from agarwood plantation. The technology to cultivate agarwood in defined plantations was developed by Prof. Robert Blanchette at the University of Minnesota, USA working with Henry Heuveling can Beek of TRP ( The Rainforest Project Foundation). Here I also provided comparative study done through this project between Simple Inducement Nailing Technology and 3^rd Generation CA Technology for further information:

Simple Inducement Nailing Technology	3rd Generation CA Technology
Only low yield	Highest possible yield
Commercially not viable	Commercially viable
High cost/ Low return	Medium cost/ High return
High labor intensity	Low labor intensity
Simple application	Easy application
Technology free	Medium cost manufacturer
Training simple	Training easy
More than 36 months	Duration 12-24 months
Not certified	Will be certified
Applied	Applied commercially
Scientifically tested	Scientifically tested

I got an information from Happy Farmers Co Ltd which is the distributor of CA Kits at Laos stated that CA Kits are the highest yielding, lowest cost and only patented treatment available. On average, a six- to nine-year-old tree can yield 10 – 50 grams of very high quality Grade A resin-saturated black and yellow chips, 200 – 250 grams of medium- high quality chips, up to one kilogram of medium and low quality flakes and powder, and 15 – 25 kg of yellow wood for producing oil and incense.
I also done several experiments ( try and error) to test which  can be consider the best in term of yield, quality and cost effective( involving malaccencis, sub-integra and crassna species). But, I cannot include here yet because still didn’t get the full results of the experiments.
Some of company that dealing with inoculation method in Malaysia are :
1. Gaharuman
2. Gaharu Nano Tech Marketing
3. Green World Aroma Enterprise
4. True Leaf
To know further about what type of inoculation inducement they are using, you all can contact directly with those company. I am not their representative , just want to share with those who are looking for those type of services. I will update more about this when I got new information or news regarding this topic.
So far, I think that’s all I can share with all of you. Maybe I am wrong, so your opinion and suggestion are very welcome and appreciated.
