Emerging Diseases

Apart from basal stem rot disease, oil palm is also affected by other diseases. These diseases were currently considered as minor and emerging diseases in oil palm cultivation in Malaysia such as bunch rot, wet stem rot, leaf spot disease and orange spotting.

Stem Wet Rot

Biology and Symptom

The first symptom of stem wet rot is usually the sudden and simultaneous death of all unexpanded spear leaves, together with the youngest expanded fronds surrounding the spears. This is followed by the appearance of a dull yellowish discoloration in the remaining fronds, which then rapidly wither and die, until the whole crown has been killed. When the trunk of an affected palm is split, it is usually found that the internal tissues have been almost completely destroyed. The disease is typified by a wet, putrid rot which is brown, yellow or greyish in colour, and has a very objectionable smell.

Rotting of internal tissues with fibrous lump inside the trunk. The outside stem is still hard.

Causal

Although there is no proven pathogen, the type of rot found in the stem suggests that a bacterium is involved. A number of commonly-rotting fungi have been isolated from diseased tissues but these are very unlikely to be primary pathogens, although possibly accelerating tissue destruction.


Disease Management and Control

There is no known control of stem wet rot. The possible association of high water-table with disease incidence indicates that drainage should be improved. Palms killed by the disease should be excavated and disposed of in the interrow to prevent their colonization by potentially pathogenic fungi.

Oil palm is the major commodity crop for Malaysia. It is important to ensure its sustainability by improving yield as well as protecting the crop from pest and diseases.

The implementation of The Malaysian Oil Palm Industry Biosecurity Plan will be our first step in protecting and preventing invasive pests, diseases or weeds from entering our country, thus securing the future of the oil palm industry in Malaysia.
