Cloning of transcripts encoding chitinases from Elaeis guineensis Jacq. Development and survival of Ganoderma sp in oil palm tissue. In the most severe cases the stem might even fracture Rees et al. Detection Observation of such symptoms in the field as mature leaves wilting and falling through malnutrition or the presence of basidiomata of the pathogen on the tree was the only method of diagnosing disease in the early days Lelong et al.

A comparative study of replanting techniques in oil palms Hashim, indicated that clean-clearing was the most effective in reducing subsequent disease incidence from Nor Azah Yusof, Email: For many years, burning the materials has been common but this is creating environmental issues in the region.

Identification of Ganoderma, the causal agent of basal stem rot disease in oil palm using a molecular method. The earliest external symptoms of basal stem rot of oil palms occur in the foliage, generally after at least half of the cross-sectional area of the stem base has been destroyed.

A possibility of chitinolytic bacteria utilization to control basal stems disease caused by Ganoderma boninense in oil palm seedling.

Infected root tissues are generally friable, with dry and powdery internal tissues. Evaluation of pressure injection of fungicides by Ariffin has indicated that tridemorph appears to limit the spread of infection.

Antagonistic fungi have been under investigation for a few decades after successful protection of stumps against Fomesannosus Rishbethfollowed by commercial control of the disease.

Banoderma online version of this article doi: Several types of plant chitinases have been detected from different parts of various plants, and are involved in the defence mechanism against fungal pathogens Liu et al.

Also the fact that roots form a small but significant source of inoculum Hasan and Turner, would suggest that clean clearing will never be able to remove all potential sources of infection. Genetic diversity of Ganoderma in oil palm plantings.

Development of Molecular Diagnostics for the detection of Ganoderma isolates pathogenic to oil palm. Polymerase Chain Reaction PCRby providing an opportunity for the amplification of certain regions of a template molecule DNA or RNAhas been of great benefit to development and innovation in a variety of PCR-based techniques with diverse applications. This condition progresses to the middle of the crown, finally affecting the spear leaves.

Current name Classification Type name Basionym Obligate or homotypic synonyms Anamorph synonyms Teleomorph synonyms Facultative or heterotypic synonyms Type of organism. Such practices have been widely adopted throughout South-East Asia, to different degrees, dependent on basal stem rot incidence in previous plantings, labour availability and the costs involved.


In another recent study, ergosterol, a membrane component of fungi, was investigated using high-performance liquid ganoddrma HPLC.

Detection and control of Ganoderma boninense: strategies and perspectives

boninenee An electrochemical DNA biosensor for ganoderma boninense pathogen of the Oil palm utilizing a New ruthenium complex, [Ru dppz 2 qtpy ] Cl2. Infection produces a dry rotting of internal tissues at the stem base or root bole and so at any stage in the disease process, the stem or root bole of the infected palm may fracture and the palm will collapse.
