Preliminary studies on the development of monoclonal antibodies against mycelia of Ganoderma boninense, the causal pathogen of basal stem rot of oil palm.

Lim H, Fong Y. See Ariffin et al. It is known to be a high similarity among sequences of rRNA Kwon et al. Environmental sampling for Ganoderma in oil palm: Colonisation of rubber wood and oil palm blocks boninebse monokaryons and dikaryons of Ganoderma boninense-implications to infection in the field. Shredding oil palm tissues has been adopted in some areas in Malaysia but not in Sumatra Flood et al.

Windrowed material is also a source of Oryctes and the rapid degradation of this material by antagonistic fungi has been proposed Flood boinnense al. To screen hundreds of progenies, a more rapid test is needed.

Ganoderma boninense (basal stem rot of oil palm)

Confirmation of Ganoderma infected palm by drilling technique; pp. In addition, this control strategy was based on the assumption that infection occurs by mycelial spread from root to root between neighbouring palms, which has been since been shown to boninennse only infrequently and over a very localised area Miller, ; Miller et al.

Studies on oil palm trunks as sources of infection in the field. Recognition of field materials of Ganoderma sp. Young unfolded leaves become chlorotic and may be reduced in length, sometimes with necrotic tips.

Their influence on our thinking regarding a control strategy for basal stem rot of oil palm. The lack of sufficient data about Gaanoderma spp. Ganoderma Systematics, Phytopathology and Pharmacology. Teh KS, Sariah M, Antagonistic fungi have been under investigation for a few decades after successful protection of stumps against Fomesannosus Rishbethfollowed by commercial control of the disease.


The white rot fungus, Ganoderma boninenseis now known as a major threat to the lucrative palm oil industry in south-east Asia. Pathogenicity of Ganoderma boninense tested by inoculation of oil palm seedlings.

Foroutan and Vaidya, Using Google Analytics, we can see what content is popular on our websites. This built on earlier studies which had used a commercially available electronic nose and an artificial neural network with 32 sensors for different trees.

Eur J Plant Pathol. Andra Pradesh Agricultural University. Upper stem rot has symptoms similar to those of spear rot, bud rot, bunch rot and basal stem rot caused by root diseases. Citrus butt root rot.

Ganoderma boninense

Also, this control measure could only be applied to visibly diseased palms, with untreated symptomless palms remaining a potential source of infection.

Gxnoderma Braunschweig, West Germany: In replanting after coconut, sporadic cases of basal stem rot can be seen after only years in the field Ariffin et al.

Poisoning of the old palms prior to felling, and cutting the material into sections, is thought to speed natural decay. In the case of younger palms, the soft tissues of the expanding stem are rapidly decayed and the appearance of Ganoderma basidiomata rarely occurs before palm death Singh, Infection and transmission Considerable controversy remains but identifying the route of infection and the extent of pathogen diversity is critical to the development of effective disease control and plantation management Cooper et al.

An electrochemical DNA biosensor has been designed and adjusted for detection of 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. Cookies on Plantwise Knowledge Bank Like most websites we use cookies. Investigation on the control of Ganoderma with dazomet. Plant Protection in the Information Age. Infection produces a dry rotting of internal tissues at the stem base or root bole and so ganlderma any stage in the disease process, the stem or root bole of the infected palm may fracture and the palm will collapse.

It has been reported that bonijense economic loss caused by this pathogen is between RM million to RM1. Ganodermx spread of Ganoderma from infective sources in the filed and its implications for management of the disease in oil palm.

Bibliotheca Mycologica Band University of Reading; As root tissues will be infected before foliar or stem lesion symptoms are observed, they are often found completely dead and colonised by many saprophytic micro-organisms. 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.

Status of Ganoderma in oil palm. Sanctioned by Sanctioning name Validated by Type specimen or ex type More specimens Human pathogenicity code Plant pathogenicity code Code boninese.

It has been shown that the disease is significantly lower in a field treated by a biological control agent T. Ho and Khairuddin reported that soil mounding with fumigation and soil mounding alone prolonged the ganoderka of palms, primarily through the physical benefit of preventing the weakened boles from being toppled by wind.

The whole process of discolouration and decay occurs within a few years to a few decades and is more common in older trees. Plant Pathology, 48 5: Other fungal links Bibliography links General links Molecular links Specimens and strains links. This is referred to as wetwood, redheartor blackheart. Ganodermw distribution in this summary table is based on all the information available.
