Knowing Palm Oil Cancer, Ganoderma

InfoSAWIT, JAKARTA – Stem rot disease is one deadly disease in palm oil plantation. It is from ganoderma sp.. To avoid it, it is better to know it in the first place to implement kinds of prevention to handle.

It may be horrifying when listening to the name. What would be if it attacks our palm oil plantation? Ganoderma is not new one in the plantation but in every single day, the plantations which have been planted for two generations would get the symptoms. But the new ones could get the same.

The disease from the fungus is not a regular one for palm oil plantations. If it once attacks, the plantation (trees) would come to an end and would make loss for the planters. After it is researched, the infection of ganoderma could spread through the spore and the contact of the roots. If in the soil, there is inoculum, it would spread fast and unavoidable.

If the trees are planted in the soil where inoculum is in, how great we handle or nurse the infected trees, they would be attacked too. Many researchers are challenged to prevent the disease, such as, using technic and doing seed research to get anti or tolerant ganoderma.

It is no doubt that the palm oil seed producers nationally offer the seeds which are tolerant to ganoderma. It could happen that this would be the solution. But it is better to know what ganoderma is actually. By knowing the first symptom, the attack could be handled well by preventing or at least, there would be isolation not to spread to other locations.

 

First Symptom and Identification

Actually, to know the first attack of ganoderma, it could be identified by the symptom. There are four symptoms to identify, they are,

a.         3 or more spear leaves are not open when the tree is not lack of water (score 1)

b.         3 or more spear leaves are not open when the tree is not lack of water and the lower part of the midrib is naturally sengkleh (score 2)

c.         3 or more spear leaves are not open when the tree is not lack of water and the lower part of the midrib is naturally sengkleh and fungus (the body of fruit/basidioscarp) is found (score 3) (Marlon Sitanggang/Head Divisi Agronomi of PT USTP)
