Lily Eurwilaichitr and Dr. Cross-infectivity and decay ability of Ganoderma species parasitic to rubber, oil palm and tea, B. However, as yet, there are no commercially available oil palm varieties with resistance to G.

Detection and control of Ganoderma boninense: strategies and perspectives

The odour profile recorded provided differentiating information that seems to be practical particularly if it is accompanied with chromatography techniques Markom et al. If Ganoderma spreads by other mechanisms, such as basidiospore dispersal, the isolation of palm root systems would be ineffective regardless of trench depth.

Title Basidiomata on base of oil palm Caption Basidiomata appear at the stem base when disease has been long, and thus extensively, established.

Development and survival of Ganoderma sp in oil palm tissue. Run Zhang 1 and Dr. Click on the language titles to launch them. Bulletin of the Imperial Institute, London, Doubts have been raised regarding the efficacy of this approach, with evidence from a number of oil palm estates suggesting that infection can still become established bonindnse earlier with each planting cycle, even after clean clearing. The earliest external ganoderam 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.

Isolation pits The isolation of symptomatic palms, by digging trenches to prevent possible mycelial spread of the pathogen to neighbouring healthy palms, has been discussed as a control measure since early this century Anon. Compilation of small ribosomal subunit RNA sequences.


No single method has yet been able to halt the continuing spread of the disease. The biology of Ganoderma lucidum on areca and coconut palms. Characteristic internal symptoms appear as light-brown dry rot lesions of both the stem and bole, occasionally with visible mycelial growth and narrow, dark bands of tissue between the light-brown lesions.

Undoubtedly, the times of ganderma 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 gamoderma one is planting oil palms after coconuts.

This built on earlier studies which had used a commercially available electronic nose and an artificial neural network with 32 sensors for different trees.

Their position usually reflects the infected area within the stem.

Furthermore, although legume cover ganodermq may accelerate decay of oil palm debris, reports have also suggested that they may encourage Ganoderma Dharmaputra et al. Ganoderma — A boninensd fungal biofactory. However, these authors tested the benefits of soil mounding in conjunction with surgery and fumigation with dazomet in mitigating the effects of infection and these treatments would be more labour intensive and involve the purchase of chemicals.

Ariffin and Idris c reported fungitoxic effects of methyl isothiocyanate to Ganoderma spp.

Firstly, there must be an injury to expose the wood. This condition progresses to the middle of the crown, finally affecting the spear leaves.

Windrowing This technique is less labour intensive than clean-clearing: Oil palm diseases and disorders. Andra Pradesh Agricultural University.

Use of antibodies for detection of Ganoderma infection of oil palm. Glyco-conjugates as elicitors or suppressors of plant innate immunity. Environmental sampling for Ganoderma in oil palm: From early studies on the biological control of wood rotting fungi, species of Trichoderma have attracted attention because of their potential antagonistic effect in controlling other fungi Rifai ; Dennis and Webster abc.


Basal stem rot of oil palm caused by Ganoderma boninense.

Gilbertson RL, Bonihense L, In the longer term, the use of resistant planting boninenze offers the greatest hope for the future control of BSR. Pale and necrotic leaf canopy of oil palms attacked by G. This is referred to as wetwood, redheartor blackheart. Spatial and sequential mapping of the incidence of Basal Stem Rot of oil palms on a a former coconut plantation.

This paper discusses the modes of infection and transmission of Ganoderma boninense and suggests techniques for its early detection.

Fifth International Mycological Congress; Using Google Analytics, we can see what content is popular on boninens websites. It is also possible that screening for secondary metabolites along with the components of fungi in the host could be an alternative technique to direct molecular methods. Although the development and spread of wood rots may differ from fungus to fungus and according to the type of tree, there are similarities. Effects of inoculum potential, shading and soil temperature on root infection of oil palm seedlings by the basal stem rot pathogen Ganoderma boninense.
