Abstract

Background: The intensive and prolonged use of synthetic fungicides, particularly mancozeb, exerts selective pressure on non-target microbial communities, potentially promoting the emergence of tolerant populations. Therefore, biocontrol agents that remain effective under such chemical stress are needed. Objective: This study aimed to evaluate the tolerance responses of Streptomyces xiangtanensis NBSP3F and Trichoderma asperellum G-4274-1 to mancozeb exposure across a gradient of concentrations. Methods: The experiment was conducted in vitro using a poisoned food technique at six concentrations (0%, 1%, 2%, 3%, 4%, and 5%) with six replications. Tolerance of S. xiangtanensis was assessed qualitatively based on colony growth, while T. asperellum was quantitatively evaluated using mycelial radial growth and growth inhibition metrics. Results: Results showed a concentration-dependent suppression of growth in both isolates. S. xiangtanensis maintained complete growth (100%) at 0–1% concentrations, decreased to 75% at 2–3%, 50% at 4%, and 25% at 5%. T. asperellum exhibited stable growth (90–100%) at 0–2%, moderate reduction (70–72.5%) at 3–4%, and a decline to 45% at 5%. Comparatively, T. asperellum showed higher physiological resilience than S. xiangtanensis under intermediate to high fungicide stress, though both isolates had reduced adaptability at the highest concentration. Conclusions: These findings indicate species-specific differences in adaptive capacity to multisite fungicidal stress, likely due to variation in metabolic flexibility and stress-response mechanisms. Collectively, both isolates demonstrate strong potential as multifunctional biocontrol agents, integrating pathogen suppression, plant growth promotion, and possible roles in pesticide-tolerant biodegradation, offering promising implications for sustainable agroecosystem management.

Abstract

Background:Indonesia’s cocoa production has declined over the past two years, despite the highly promising market potential for cocoa. One strategy to enhance the growth of cocoa seedlings is through the improvement of planting media by incorporating organic amendments such as vermicompost. Objective: This study aimed to (1) evaluate the effectiveness of different vermicompost application rates on the growth of cocoa seedlings (Theobroma cacao L.), and (2) determine the optimal vermicompost rate for cocoa seedlings. Methods:The experiment was conducted over a four-month period at the experimental field of the Politeknik Pertanian Negeri Payakumbuh, employing a Completely Randomized Design (CRD) with six levels of vermicompost application rates: 0, 25, 50, 75, 100, and 125 g plant⁻¹, each treatment replicated four times. Observations included soil parameters (total nitrogen, available phosphorus, organic carbon, and soil pH) and plant growth parameters (plant height, number of leaves, stem diameter, shoot dry weight, and root dry weight). Data were analyzed using ANOVA at a 5% significance level, followed by LSD test. Results:Vermicompost application significantly affected plant height, leaf number, stem diameter, shoot dry weight, and root dry weight. The application rate of 125 g plant⁻¹ resulted in the most optimal growth, with plant height of 22.78 cm, 16.13 leaves, shoot dry weight of 2.99 g, and root dry weight of 1.70 g. These improvements were associated with enhanced soil chemical properties, particularly increased total nitrogen, available phosphorus, organic carbon, and soil pH Conclusions:Vermicompost at a dose of 125 g plant⁻¹ is effective in improving the growth of cocoa seedlings and soil chemical properties, and is recommended as an optimal organic amendment for cocoa nursery.

Abstract

Background: Empty oil palm bunches (EFB) are underutilized solid waste. Liquid smoke from EFB pyrolysis contains bioactive compounds as an eco-friendly natural insecticide. Objective: This study analyzes the chemical composition of EFB liquid smoke and reviews its potential as a natural insecticide against plant pests. Methods: Liquid smoke was produced by EFB pyrolysis at 150–250°C for six hours. Chemical composition was analyzed using GC-MS. A literature review (2016–2026) evaluated the insecticidal potential of identified compounds. Results: GC-MS detected 60 compounds. The 19 compounds with highest relative content belonged to phenolics, heterocyclics, organic compounds, and organic acids. Phenol was the most dominant (21.68%), followed by pyridine (5.68%), p-cresol (4.23% and 1.86%), and 2-methyl-2-cyclopenten-1-one (4.14%). Literature indicates these compounds act as natural insecticides through multiple mechanisms: direct toxicity (membrane damage, protein denaturation, enzyme inactivation), metabolic disruption (inhibition of electron transport chain and ATP production), and behavioral changes (antifeedant and attractant). Synergistic effects between phenolics and ketones or pyridine derivatives may enhance insecticidal efficacy. Conclusions: EFB liquid smoke contains 60 compounds, with 19 major compounds from phenolics, heterocyclics, organic compounds, and organic acids, showing potential as natural insecticides. However, bioassays against model pests (e.g., Spodoptera litura, Sitophilus oryzae) and phytotoxicity tests are still required

Abstract

Background: Red Yellow Podzolic (Ultisol) soil has low fertility, which inhibits the growth of Betara areca nut (Areca catechu L.) seedlings. The combination of vermicompost and coconut water liquid organic fertilizer (LOF) has the potential to improve this condition. Objective: This study aimed to evaluate the main and interactive effects of vermicompost and coconut water LOF on the growth of Betara areca nut seedlings in Ultisol soil. Methods: The research employed a 4×4 factorial completely randomized design with three replicates. The first factor was vermicompost dosage (0, 50, 100, and 150 g/polybag), and the second factor was coconut water LOF concentration (0%, 25%, 50%, and 75%). Observed parameters included plant height, number of leaf sheaths, stem diameter, leaf area, leaf sheath length, fresh weight, dry weight, root length, and root volume. Results: The interaction between vermicompost and coconut water LOF significantly affected plant height, number of leaf sheaths, stem diameter, leaf area, leaf sheath length, and root volume. The best treatment was the combination of 150 g/polybag vermicompost and 75% coconut water LOF (K3P3). Individually, vermicompost at 150 g/polybag significantly affected all parameters except interaction, while coconut water LOF at 75% concentration significantly affected all parameters except dry weight. Conclusions: The combination of vermicompost and coconut water LOF significantly enhances the vegetative growth of Betara areca nut seedlings, with the K3P3 treatment being the most effective

Abstract

Background: Spodoptera frugiperda is a pest that causes damage and economic losses to corn plants. One of the biological agents that can be used to control S. frugiperda is the entomopathogenic fungus Metarhizium anisopliae. Objective: This study aimed to determine the most virulent isolate of M. anisopliae against S. frugiperda eggs and to evaluate its effect on larval development. Methods: This study used an experimental method with a Completely Randomized Design (CRD) consisting of 5 treatments and 5 replications. The treatments were (A) M. anisopliae C5IA, (B) M. anisopliae SRJ, (C) M. anisopliae 3B, (D) M. anisopliae Metatek, and (E) control (without fungal treatment). The conidial density used was 10⁸ conidia/ml. The fungus was applied to egg masses of S. frugiperda using a spraying method. The parameters observed were percentage of unhatched eggs, mortality of first instar larvae, percentage of pupae formed, and percentage of adults formed. Data were analyzed using analysis of variance (ANOVA) followed by LSD test at the 5% significance level. Results: All tested isolates of the entomopathogenic fungus M. anisopliae caused egg mortality and affected the life development of S. frugiperda. The percentage of unhatched eggs ranged from 41.92% to 92.00%. The most virulent isolate was M. anisopliae 3B, which was able to control eggs with an unhatched egg percentage of up to 92.00% Conclusions: The isolate M. anisopliae 3B was the most virulent isolate against eggs of S. frugiperda and has potential to be developed as a biological control agent for fall armyworm management.

Abstract

Background: The fungus Beauveria bassiana (Balsamo) Vuill is an entomopathogenic fungus widely used as a biological control agent against insect pests in plantation, food, and horticultural crops. Beyond its role as a biocontrol agent, B. bassiana has also been reported to enhance seed germination and early growth of shallot plants. Objective: his study aimed to determine the germination response of shallot seeds (Allium ascalonicum L.) to seed soaking treatment using B. bassiana at varying concentrations and soaking durations. Methods: TA field experiment was conducted from January to March 2026 using a factorial Randomized Complete Block Design (RCBD) with two factors: concentration (V) and soaking duration (P). Parameters observed included germination percentage, germination rate, shoot height, leaf number, leaf length, root length. Results: The results showed that the concentration of 15 ml/L (V3) gave the best effect on all parameters, while the soaking duration of 9 hours (P1) was optimal and not significantly different from longer soaking durations. The combination treatment of V3P1 (15 ml/L + 9 hours) produced the highest germination percentage (35% at 25 days after planting), the best germination speed (11.3 days), as well as superior shoot height and root length. The ability of B. bassiana to enhance growth is thought to be due to the production of phytohormones such as auxin and gibberellin. Conclusions: In conclusion, soaking shallot seeds in a suspension of B. bassiana at a concentration of 15 ml/L for 9 hours is recommended to improve seed viability and growth
