“…Infested planting may harbour many infested roots, while a small infected root piece could be an infective inoculum (Rees et al, 2007). The abundance of inoculum sources in a recent planting was considered responsible for the disease increase over several plant generations (Priwiratama et al, 2020). Several control measures, including cultural practices, mechanical, chemical, and microbial treatments, were applied to control BSR; however, none has been really able to reduce the spread of the disease (Siddiqui et al, 2021).…”

Basal stem rot (BSR) caused by Ganoderma boninense remains the most destructive disease in oil palm monoculture plantations. This study investigates the nature of Ganoderma infection and survival under mixed planting with rhizomatous plants and its impact on the growth of oil palm. Two mixed plants (oil palm seedling and Java turmeric, galangal, or ginger) and single planting of those plants were inoculated with Ganoderma boninense-colonised rubber wood block (RWB). The results showed that Ganoderma inoculation in mixed planting caused an infection on both host species (dual-host infection). Under mixed planting for 9 months with Java turmeric and ginger, the disease index of oil palm was reduced by 47%-59% compared to the single planting. Planting oil palm with rhizomatous plants showed a minor effect on the decay of RWB and fungal survival but planting with ginger induced basidiocarp formation. The rhizomatous plants habitually did not exhibit allelopathic inhibition of oil palm growth. Growth of Ganoderma-infected seedlings was recovered under mixed planting. This study highlights a novel insight that mixed planting with rhizomatous plants can interfere with and reduce Ganoderma disease in oil palm.

“…The disease may be reduced by clearing OP before they reach the greatest susceptibility ( Rees et al, 2009 ). As reported, removal of Ganoderma inoculum sources during replanting contributes to lower BSR incidence on oil palm in the first 9 years after planting whereas the incidence of BSR was maintained under 5% ( Priwiratama et al, 2020 ). Digging trenches around infected palms ( Wakefield, 1920 ) may have some value but requires scientific testing although disease spread by basidiospore dispersal would render the method useless ( Pilotti et al, 2018 ).…”

“…Soil mounding around the base of mature diseased palms can delay the development of BSR ( Turner, 1981 ). Surgery-mounding of Ganoderma-infected palms can prolong the lifetime of the infected palms for 2 to 3 years ( Priwiratama et al, 2020 ). However, these procedures require assessment in a rigorous scientific manner in field conditions to validate the method as a potential BSR management technique.…”

The rapid expansion of oil palm (OP) has led to its emergence as a commodity of strategic global importance. Palm oil is used extensively in food and as a precursor for biodiesel. The oil generates export earnings and bolsters the economy of many countries, particularly Indonesia and Malaysia. However, oil palms are prone to basal stem rot (BSR) caused by Ganoderma boninense which is the most threatening disease of OP. The current control measures for BSR management including cultural practices, mechanical and chemical treatment have not proved satisfactory. Alternative control measures to overcome the G. boninense problem are focused on the use of biological control agents and many potential bioagents were identified with little proven practical application. Planting OP varieties resistant to G. boninense could provide the ideal long-term solution to basal stem rot. The total resistance of palms to G. boninense has not yet been reported, and few examples of partial resistances have been observed. Importantly, basidiospores are now recognized as the method by which the disease is spread, and control methods require to be revaluated because of this phenomenon. Many methods developed to prevent the spread of the disease effectively are only tested at nursery levels and are only reported in national journals inhibiting the development of useful techniques globally. The initial procedures employed by the fungus to infect the OP require consideration in terms of the physiology of the growth of the fungus and its possible control. This review assesses critically the progress that has been made in BSR development and management in OP.

“…Mentioned that BSR increases in this 2nd generation planting area in Bukit Sentang estate, North Sumatra. BSR is a severe disease of oil palm, which can reduce yields by 50-80% [6]. Over the past two or three decades, it has increased due to its spread from infection foci at a greater rate following repeated cycles of crop planting on infested sites [5].…”

Biological agents are critical in the management of major diseases in oil palm plantations. The potential of arbuscular mycorrhiza fungi (AMF) and Trichoderma spp. to control basal stem rot disease was investigated in this study. Three-month-old seedlings treated with AMF since the beginning of planting demonstrated AMF colonization of the roots. With a 25 gram AMF treatment in the main nursery, AMF colonization increased by 85.99% in TBM-1 (the 1-year immature plant). In TBM-2, AMF colonization increased by 86.00-97.33% (2-year immature plant). All of the treatments started with 30 grams of Trichoderma spp. applied at the start of pre-nursery planting. Root colonization and the number of spores in the root rhizosphere in TBM-2 had a strong relationship (2-year immature plant). AMF inoculation had a significant impact on root colonization and spore number response. According to this study, the application of 25 grams of AMF in the pre-nursery and main nursery, as well as repeated additions at planting, were found to be effective in controlling attacks of basal stem rot disease through early prevention strategies.
