Spear Rot Disease in oil palm immature

 Planting healthy oil palm seeds is the dream of all farmers/planters. by maintaining all the main healthy plants, the expected production potential will be achieved. In practice, in the field, there are several challenges faced by farmers in achieving this goal, including shoot rot or crown rot.


    Pus rot in oil palm is known as Spear Rot Disease. Generally this disease occurs in immature plants (TBM) planting age 1 year to 2 years. This disease is identified due to the presence of pathogenic fungi. This decay rot attack can be classified according to the level of attack

1. Light Attack

    Mild attack of pupus rot can be seen from the presence of brown lesions on young pupus or spots of fungus at the base of the pupus

2. Medium Attack

    Pupus the middle to the base of rot occurs. The top part of the pupus is starting to wither while the other midges are still green and have no symptoms.

3. Heavy Attack

    Pupus is completely rotten and easily removed, followed by other fronds starting to brown and dry.

Preventive measure

    It is still possible to control mild and medium attacks by applying a fungicide regularly with a span of a week until the new pups are fresh and there are no symptoms. The main attacks heavily attacked must be replaced and inserted again with new trees. Before planting, the planting point is watered first with a fungicide solution.

Census

A census was conducted to find out early symptoms of pupus rot attack. The census is carried out from the time the tree is planted. The census was carried out by visiting all the trees of the oil palm, identifying any symptoms of the initial attack. Fungicide application is carried out when there are symptoms of attack.
