“…Infection of G. boninense was measured at the end of trial (7 month after mixed planting or 6 months post-inoculation) by counting percentage number of infected main root (number of main roots showing typical necrotic symptoms / total number of main roots of individual palm × 100%) and length of necrotic main root (total length of necrotic lesion of main roots / total length of main roots of individual palm × 100%). Colonization of inoculated G. boninense on the necrotic lesion was confirmed by re-isolation of G. boninense from surface sterilized necrotic root on a semi-selective Ganoderma medium [8] and followed by microscopic examination. Disease symptoms were also examined for necrotic lesion on bole (swollen stem base) of oil palm by cutting the bole longitudinally at the end of trial.…”

Basal stem rot (BSR) caused by long-term survival fungus Ganoderma boninense is the most important of oil palm disease that difficult to be controlled. Perennial herbaceous species are potentially developed for long-term BSR control and applied as mixed planting with oil palm. This research was aimed to study the competition effects of mixed planting with edible herbaceous perennial plants (edible canna (Canna indica), arrowroot (Maranta arundinacea), cocoyam (Xanthosoma sagittifolium), and water yam (Dioscorea alata) on growth of oil palm seedlings. Two competition trials (non-inoculated and Ganoderma-inoculated trial) were conducted. The herbaceous plants were grown together with oil palm seedling in a polybag filled with 40 L field soil. Mixed planting of Ganoderma-inoculated oil palm and herbaceous plants and grown on a large soil volume resulted in a minor infection with a high variation in severity leading to insignificant effect of herbaceous competition on Ganoderma infection. Herbaceous competition significantly suppressed oil palm seedling growth under both inoculated with Ganoderma and without inoculation. Arrowroot exhibited as the most competitive herbaceous species and followed by canna and cocoyam. Water yam showed a weak competitive against oil palm seedling since only a minor interference in all observed growth characteristics.

“…This ingredient also induced the formation of brown halo around the colony as illustrated in Figure 2. Another ingredient in part B, namely pentachloronitrobenzene (PCNB), was believed acting as a carbon source in the medium to allow the growth of Ganoderma [16].…”

“…Unfortunately, GSM could not be used in Indonesia due to the restriction of the use of PCNB according to Indonesia's government regulation No. 85/1999 on Toxic and Hazardous Waste Management, which stated that PCNB is considered as a hazardous and toxic chemical [16]. United States Environmental Protection Agency (EPA) also labelled PNCB as a carcinogenic element.…”

Discovering the Ganoderma Boninense Detection Methods Using Machine Learning: A Review of Manual, Laboratory, and Remote Approaches

Ganoderma disease is a kind of infection that actuates oil palm death. Early detection of Ganoderma disease is the most recommended strategy for proper treatment and disease control plan to be taken promptly. In this paper, the detection methods for Ganoderma disease were reviewed and categorized accordingly. It was found that the combination of remote sensors and machine learning techniques could identify the disease up to four severity levels, including the early stage of infection. It also significantly reduced the labor and time costs compared to the traditional visual inspection and lab-based approaches. In terms of machine learning, support vector machine (SVM) using the idea of finding a hyperplane was suggested as the best classifier in several studies. Despite only one research was done on ANN and no research evaluating CNN and GAN in Ganoderma disease detection; ANN, CNN and GAN were recognized as the potential machine learning techniques that could enhance the detection system.INDEX TERMS Basal stem rot, Ganoderma, machine learning, oil palm, remote sensors.
