Title Later foliar symptoms Caption Pale and necrotic leaf canopy of oil palms attacked by G. Cultural Control The identification of diseased palms is crucial to control Sanderson, and with the advent of rapid tests, diagnosis may be quicker in future allowing control measures to be implemented at an earlier stage. Received Jul 31; Accepted Oct Development of molecular diagnostics for the detection of Ganoderma isolates pathogenic to oil palm.

Distribution Maps Top of page You can pan and zoom the map. This paper discusses the modes of infection and transmission of Ganoderma boninense and suggests techniques for its early detection. Induction of systemic resistance of cucumber to Colletotrichum boninenxe by select strains of plant growth-promoting boninenes.

Title Boninensee Caption Ganoderma basidiomata on base of oil palm. Antagonistic fungi have been under investigation for a few decades after successful protection of stumps against Fomesannosus Rishbethfollowed by commercial control of the disease.

Unfortunately, the test proved to be not species-specific as antibodies cross-reacted with other species Utomo and Niepold Meanwhile, the ability of trees to express glucanase and chitinase provides a bonimense target for genetically resistant trees.

However, as there is no evidence of any direct effect, improvement in growth conditions, although beneficial to the palm, cannot be regarded as direct control effects against basal stem rot disease Turner, Wood decay, lignicolous fungi, and decline of peach trees in South Carolina.


Preliminary results on trunk injection ganodera fungicides against Ganoderma basal stem rot in oil palm. Encyclopedia of Life EOL.

Ganoderma root disease of lowland tea Camellia sinensis in Malaysia: Close Find out more. Chitinase levels in rice cultivars correlate with resistance to the sheath blight pathogen Rhizoctonia solani.

Nuclear 18S rDNA analysis may also be used to provide molecular evidence on the long distance dispersal of Ganoderma across the southern hemisphere Ganodema and Buchanan and has already shown the diversity of wood-decaying fungi in India Singh et al. Brackets basidiomata can be observed on the ends of cut roots. It is known that plants synthesize different isozymes of chitinase using a multigene family with diverse functionality van Hengel ganodermq al.

The process does not necessarily ganodrma and may stop at any stage due to quick healing boninenxe the wound, natural gaoderma of the wood or some antagonistic relationship between microorganisms.

Preliminary studies on the development of monoclonal antibodies against mycelia of Ganoderma boninense, the causal pathogen of basal stem rot of oil palm. Ariffin and Idris c reported a number of histopathological studies showing that the fungus colonized the cortex, endodermis, pericycle, xylem, phloem and pith of the palm. In an enzyme-linked immunosorbent assay, ELISApolyclonal antibodies were employed and showed relatively good negative results.

Other fungal links Bibliography links General links Molecular links Specimens and strains links. All wood rots grow inside the wood cells and degrade cell wall components. This built on earlier studies which had used a commercially available electronic nose and an artificial neural network with 32 sensors for different trees.

Basal stem rot in Indonesia. However, this agronomic practice has generally proved to be ineffective either because the trench depths were insufficient to remove all infected root material Hasan and Turner, or because the trenches were not maintained.

Ganoderma boninense (basal stem rot of oil palm)

The cells around the injured area oxidize and discolour due to biochemical bninense. Genetic structure of a population of Ganoderma boninense on oil palm. N-acetylglucosamine and glucosamine-containing arabinogalactan proteins control somatic embryogenesis. A selective medium for the isolation of Ganoderma from diseased tissues.


In fact, there are at least ten different techniques which have been used in attempts to manage the disease, with varying levels of success. As the disease progresses, palms may obninense on a pale appearance, with retarded growth and spear leaves remaining unopened.

Methods using infested wood block inoculum have been documented by Rees and colleagues who have also shown that shading of seedlings temperature both have a dramatic effect on disease Rees et al. This will help to protect your privacy.

Other Trichoderma and Gliocladium species are also active against that pathogen but are better at degrading organic matter in the field. Infestation des racines aeriennes du palmier a huile par des chenilles genre Sufetula Walker Lepidoptera: Using Google Analytics, we can see what content is popular on our websites.

Windrowed material is also a source of Oryctes and the rapid degradation of honinense material by antagonistic fungi has been proposed Flood et al. Polyclonal antibody against washing filtrate of mycelium culture of Ganoderma sp.

Navaratnam S, Chee K. Chemical treatments Although investigated as an option, injection of fungicides such as hexaconazole is rarely practiced because this method has not shown to provide effective control Chung Undoubtedly, the times of greatest practical significance for the control of basal stem rot in oil palm is during replanting second or third generation oil palm on oil palm or at the time of preparation of a site, especially when one is planting oil palms after coconuts.
