Abstract

Entomopathogenic mushrooms (CEPs) double function as biocontrol agents against pests and as biostimulants that support plant growth through the production of hormones such as IAA and gibberelline. The application of CEP as a biostimulant can be done through seed treatment, with effectiveness greatly influenced by the type of mushroom and the duration of soaking. This study aims to evaluate the effect of the length of seed soaking in CEP suspension on germination, vigor index, and early plant growth. The three types of CEP used are Beauveria bassiana, Metarhizium anisopliae, and Trichoderma asperellum. Corn seeds are soaked in a conidia solution with a concentration of 1 × 10⁸ conidia/ml and sterile aqueducts for 3, 6, 12, and 24 hours. Observations were made on the percentage of sprouts (day 7), vigor index (day 12), and seedling growth (day 28). The results showed that soaking the seeds in CEP suspension was able to improve all growth parameters. Of the four durations tested, soaking for six hours gave the most optimal results in increasing germination, vigor, and early growth of corn plants.

Abstract

This study aims to explore and select endophytic fungi from oil palm plants (Elaeis guineensis Jacq) which have the potential to be entomopathogenic to insect pests. Endophytic fungi are microorganisms that live in plant tissues without causing symptoms of disease, but some species are known to be able to infect insects and act as biological control agents. The research was carried out through the isolation of mushrooms from healthy oil palm roots, stems, and leaves obtained from PTPN III Silau Dunia's plantation, North Sumatra. A total of 120 isolates were successfully identified from 8 genera, with Fusarium oxysporum being the dominant species. Pathogenicity tests on Tenebrio molitor larvae showed that some isolates had high entomopathogenic activity, with mortality rates reaching 90% at concentrations of 20 × 10⁶ conidia/mL. These results suggest that endophytic fungi have great potential as a natural bioinsecticide in oil palm pest control. The use of biological agents is expected to be an effective and environmentally friendly alternative in supporting sustainable agricultural systems.

Abstract

Oil palm (Elaeis guineensis Jacq) is a strategic plantation commodity in Indonesia that plays an important role in the national economy. However, the productivity of these plants is often hampered by pest attacks such as fireworms (Setora nitens) and horn beetles (Oryctes rhinoceros). So far, pest control has relied more on synthetic pesticides that have a negative impact on the environment and health. This study aims to explore the potential of local entomopathogenic fungi from oil palm rhizosphere soils as biological agents for pest control. The research was carried out through the stages of isolation, morphological characterization, and bioassay tests on Tenebrio molitor larvae. The results showed six mushroom isolates, namely Aspergillus sp., Beauveria sp., and Trichoderma sp. From the bioassay test, three isolates were pathogenic to the larvae, with the isolate Beauveria sp. (CRT 03) showed the highest mortality of 85%, LT₅₀ for 4.26 days, and mycosis 55.88%. These results show that Beauveria sp. CRT 03 has high potential as a local bioinsecticide. This research supports the development of sustainable pest control in oil palm plantations through the use of environmentally friendly biological agents.
