Charcoal base rot is caused by fungal pathogen Ustulina deusta. The occurance of this species is very and has little impact in terms of economic for oil palm industry in Malaysia.
This disease infected young palm (below 4 years) and mostly infect rubber tree, coconut and even tea.
As you can see in the picture, the foliar of infected palm became so dried!! Extra dried! Thats one of the symptom! Then you can see the black hole so called like charcoal at the basal of its trunk..Thats the main symptom..Thats why they call it Charcoal base Rot..Alike isnt it?
Then, the roots of the infected palm also become dry then usual..So simple to recognise this disease guys! Got Charcoal hole, dry foliar and roots and thats the one...
Here come the secondary infection!Because there is a hole then here come the termites army which can make a hefty problem to your neighbouring palm..Watch out!
Opss!! You got pest larva too inside there! Could be a perfect breeding habitat for Rhinoceros beetle..
Control: Get rid of the infected palm..
