“…The BCA is also highly specific towards the targeted pathogen without affecting the normal flora. Over the past years, there have been extensive studies on the identification of effective BCA for controlling BSR disease (Musa et al, 2018;Naidu et al, 2018;Muniroh et al, 2019). Their potentials have been investigated initially via various in vitro studies for screening and better understanding purpose prior to greenhouse and field trials.…”

“…The BCA may utilise a single or an array of mechanisms in inhibiting a pathogen. In many BCA studies, plant growth promotion (PGP) was one of the benefits demonstrated apart from disease suppression (Nur Azura et al, 2016;Muniroh et al, 2019). In some cases, the degree of suppression by BCA towards plant pathogens tends to be lower when tested in field compared with the result achieved on agar plate for the same BCA.…”

“…Ganoderma species are saprophytic fungi indigenous tropical rainforest; however, in certain situations it becomes pathogenic (Pilotti 2005;Cooper et al 2011). In addition, Ganoderma is transmitted through air, besides through root contact, with basidiospores (Rakib et al 2014), has many host plants (Muniroh et al 2019), and forms a retaining structure like sclerotium (pseudosclerotia) (Darmono 2000).…”

“…Some methods that were developed such as making a mounding at the stem base, "stem surgery" (removing diseased tissue), making isolation trenches, sanitation, land ploughing during oil palm plantation replanting, using fungicides, using cover crop legumes, or oil palm fertilizing improvements. The results of these methods vary greatly (Fee 2011;Wong et al 2012;Priwiratama et al 2014;Muniroh et al 2019). Biological control is an alternative control method that is the focus of current development (Muniroh et al 2019).…”

Abstract. Supriyanto, Purwanto, Poromarto SH, Supyani. 2020. Evaluation of in vitro antagonistic activity of fungi from peatlands against Ganoderma species under acidic conditions. Biodiversitas 21: 2935-2945. The use of peatlands is a significant contributor to the world’s palm oil production. A serious problem of oil palm plantations in peatlands is the high incidence of basal stem rot (BSR) disease caused by Ganoderma, which has a higher attack rate than on mineral soils. There is no effective way to control Ganoderma in peatlands. At present, the effort for the same focuses on environment-friendly biological methods; however, this is constrained by the unavailability of appropriate biological agents for peatlands. The development of biological control agents for peatlands is hampered by limited data on biological control of Ganoderma in peatlands. This research was conducted to evaluate the in vitro antagonistic activity of fungi isolated from a peatland in acidic pH conditions. Twenty-seven Ganoderma-antagonistic fungi from peatland were evaluated for their activity and their ability to antagonism in vitro within a pH range of 2-7. The results show that most antagonistic fungi from peatland, based on biomass weight, the sporulation ability, and germination of conidium, were able to grow optimally at pH 3.0-4.0, indicating that most of the Ganoderma-antagonistic fungi from peatland can be used as biological control agents for BSR on oil palms in peatlands.

The globally vital oil palm, a major oil producer, confronts productivity challenges due to Ganoderma boninense (Gb), causing output decline. Chemical control efforts have proven ineffective, prompting exploration of microbial‐based biocontrol. While single fungal biocontrol research exists, the impact of employing multiple biocontrols concurrently to combat Ganoderma and enhance oil palm growth remains uncharted. This study examined four soil‐derived fungal isolates for their ability to antagonize Gb PER71 in vitro. Molecular identification categorized them as Talaromyces spp. and Penicillium sp. Moreover, all isolates were revealed to have at least three plant growth‐promoting (PGP) traits and were shown to have phosphoric hydrolase, ester hydrolase, peptide hydrolase, and glycosidase activities which are essential for plant growth. Furthermore, the synergistic evaluation of fungal isolates was tested against Gb PER71. One out of six combinations of fungal isolates showed a synergistic effect in vitro, and two showed a synergistic effect in planta. The application of single and combined fungal isolates tested in planta also suppressed Gb PER71 and enhanced oil palm growth compared to control groups. The findings indicate the promising potential of these isolates as biocontrol agents (BCAs) and bioformulations against Gb in oil palm cultivation.
