Experiments in which an enormous number of Ganoderma spores were released in a field but did not infect most trees Ho and Nawawi have indicated that infected tissues in the soil are more ganodemra to spread the disease to healthy roots than airborne spores. Utomo C, Niepold F.
For the purposes of this data sheet only control of the disease in oil palms and coconuts is presented. This article has been cited by other articles in PMC.
Ganoderma in Malaysia-current status and research strategy.
The potential of chitosan in suppressing Ganoderma boninense infection in oil-palm seedlings. Basal stem rot of oil palm caused by Ganoderma boninense – an update.

However, economically, the price of palm oil is so low the labour costs to conduct this work especially where there is a high incidence of bonineense disease, are prohibitive boninejse many oil palm plantations. Foroutan and Vaidya, Flood and her colleagues stated that USR invariably causes discrete lesions originating from the frond base and spreading in successive wave of rot, each delimited by the brown or black line Flood et al.
In Yusof et al. Treatment and control in established plantings.
Ganodefma, with the advent of rapid diagnostic tests See Diagnostic Methods there is a possibility of using chemical control earlier and thus possibly more chance of success.
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 ganoderna rot disease Turner, Studies in Mycology, Root inoculation of oil palm seedlings with Ganoderma sp.
This article is published under license to BioMed Central Ltd. Register new name species, genus, family, etc Register new type specimen of existing taxa epitype, neotype, etc. At the end of their experiments, Sariah and Zakaria reported that disease incidence in treatments using T. The gamoderma option, DNA-based nanosensors and DNA microarrays, have been found to be easier to operate, faster, more accurate and more economically viable than conventional PCR-based techniques.
Ganoderma boninense
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 areas with a high incidence of basal stem rot, it is generally thought that all remaining fragments from the previous crop should be brought to the surface for subsequent removal. Visual symptoms alone are thus not necessarily diagnostic of basal stem rot, as other factors leading to water stress, such as drought, high soil water salinity or hyperacid soils also cause similar foliar symptoms Turner, 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.
Hasan and Turnerreported that subsequent infection incidence decreases with increased clearing depth, implying that clean clearing may frequently not be sufficiently thorough in practice.
Sequence analysis and gene expression of putative exo- and endo-glucanases from oil palm Elaeis guineensis during fungal infection. Antagonistic effect of four fungal isolates to Ganoderma boninense, the causal agent of basal stem rot of oil palm.
Windrowed material is also a source of Oryctes and the rapid degradation of this material by antagonistic fungi has been proposed Flood et al.
After an attempt to design a PCR technique Idris et al. Ganoderma Diseases of Perennial Crops. Cauterization by burning of the root-ends along boninennse sides of the pits is also common.
Ariffin and his colleagues had earlier revealed that the black line observed in the stem of oil palm infected with G. Infection and transmission Considerable controversy remains but identifying boninene route of infection and the extent of pathogen diversity is critical to the development of effective disease control and plantation management Cooper et al. This Add-on is available at http: Copyright Chin Khoon Min.
Specimens and strains links: Their influence on our thinking regarding a control strategy for basal stem rot of oil palm.
Usefulness of soil mounding treatments in prolonging productivity of prime-aged Ganoderma infected palms. Biological control Ganodwrma fungi have been under investigation for a few decades after successful protection of stumps against Fomesannosus Rishbethfollowed by commercial control of the disease. Glyco-conjugates as elicitors or suppressors of plant innate immunity.
Early symptoms in coconuts in South Asia comprise a reduction in the size of fruits and nuts, with a wilting and necrosis of lower foliage. As presence of fungal hyphae almost exclusively on one side of the boninwnse line precludes the possibility of a dual bnoinense involving another fungus and clearly indicates that G.
