What is pork potato? Not sure about oleander but we wanted to use the best which is gingko according to your recommendation. If gingko extract is not possible to get, then we have to use Jerusalem artichoke. Next option is Jerusalem artichoke which is practical to us as we can allocate some land to just plant this for sustainability. And also planting potato is to use as medium for JMS production. We have a large area size to practuse JADAM.
How to try with decly glucoside? Pls advise on recipe.  

Aren't there oleanders in Malaysia? It is stronger than pork potato.
Among the eco-friendly surfactants, decyl glucoside was judged to be the most suitable, so we are currently experimenting with applying it to various crops. It seems to give good results.

If you also want to try decyl glucoside, please try it in the 1~5L category based on 500L.
