Abstract

Background: Aspergillus flavus is a fungus that produces aflatoxin, a toxic compound that can contaminate food products, especially nuts. The impact caused by A. flavus causes significant losses for peanut-producing countries in cases of international trade. A. flavus infection in peanuts causes physical changes and quality, as well as a decrease in seed germination. Environmentally friendly control efforts for A. flavus can be carried out by utilizing biological agents such as Trichoderma spp. This study aims to evaluate the ability of T. harzianum and T. asperellum to inhibit the growth of A. flavus. This study also evaluates bio-priming methods enriched with Trichoderma spp. to optimize peanut seed germination. Methods: The research used a factorial Completely Randomized Design (CRD) of 2 factors. The first factor is the isolate species Trichoderma spp. namely T. harzianum (T1), T. asperellum (T2), and Control (T0), namely A. flavus without biological control treatment. The second factor is the application method, which includes the bio-priming (B1) and bio-matrixpriming (B2) methods. Each treatment combination was repeated 4 times, and the number of seeds used was five in each unit. Results: T. harzianum showed the highest inhibitory ability against A. flavus in the in vitro test, namely 49%. Bio-priming treatment containing the active ingredient T. harzianum is the best treatment for increasing peanut germination by 95%. Conclusions: The research results showed that bio-priming treatment with the active ingredient T. harzianum increased the germination rate significantly compared to other treatments.

Abstract

Fusarium oxysporum is the pathogen that causes moler disease which can reduce the productivity of shallot plants. The use of cultivars greatly affects the production. Control method that is more environmentally friendly is currently being pursued towards organic farming. Fobio is a biopesticide containing plant root microorganisms as biological control agents. This study aims to determine the effect of Fobio biopesticide on Fusarium wilt (moler) disease incidence and production of three shallot cultivars. The experiment was conducted in the shallot planting area of Sukorejo Village, Rejoso District, Nganjuk Regency, East Java. This experiment was arranged in the split plot design with two factors. The main plot of the concentration of the biopesticide formula (Fobio) consisted of 3 levels namely control (chemical fungicide), 5 ml/liter, and 10 ml/liter, and the subplot of shallot cultivar consisted of 3 types namely Tajuk, Biru Lanchor, and Super Philip. The observation in this study were the incubation period, disease symptoms, disease intensity, and shallot bulb yield. The results showed that Fobio biopesticide at the concentration of 10 ml/liter caused the same disease suppression as chemical fungicide (control) in the three shallot cultivars with the disease incidence of 18.78%. Fobio biopesticide concentration of 10 ml/liter had also the same effect as chemical fungicide on the production of those shallot cultivars, with the average wet weight of 2.25 kg/treatment and dry weight of 1.49 kg/treatment.

Abstract

Pisang (Musa paradisiaca L.) merupakan salah satu kebutuhan pokok bagi masyarakat Bali, terutama umat Hindu, yang mendorong pengembangan budidaya secara intensif di berbagai jenis lahan. Namun, pengembangan ini dihadapkan pada kendala penyakit layu fusarium yang disebabkan oleh Fusarium oxysporum f.sp. cubense. Penelitian ini mengevaluasi efektivitas biopestisida FOBIO dalam menekan intensitas serangan fusarium serta meningkatkan pertumbuhan tunas pisang. Penelitian dilakukan menggunakan Rancangan Acak Kelompok Faktorial (RAKF) dengan dua faktor: ketinggian tempat (650-950 mdpl dan 25-40 mdpl) serta konsentrasi biopestisida (kontrol dan FOBIO 7,5 ml/liter). Hasil penelitian menunjukkan bahwa aplikasi FOBIO 7,5 ml/liter mampu menurunkan persentase serangan dari kategori berat menjadi sedang sebesar 18,9%. Serangan tertinggi terjadi di dataran tinggi (650-950 mdpl) dengan intensitas 34,1% (kategori berat), di mana FOBIO tidak efektif dalam menurunkan intensitas serangan. Meski tidak signifikan, aplikasi FOBIO meningkatkan jumlah tunas baru sebesar 8,4 tunas di dataran tinggi.

Abstract

Spodoptera exigua is a major pest of shallots (Allium ascalonicum L.), capable of causing up to 100% yield loss if uncontrolled. Streptomyces sp. is a soil-dwelling Actinomycetes bacterium that can be used to control S. exigua. This study aimed to determine the potential of Streptomyces spp. isolates from shallot fields as an entomopathogen against S. exigua. The research employed a Factorial Complete Randomized Design (CRD). The first factor consisted of one Streptomyces spp. isolate obtained from the Pare-Kediri region (BMP) and three isolates from Sidera-Palu (BMS1, BMS2, and BMS3). The second factor was the concentration of the Streptomyces sp. suspension consist of 0%; 5%; 10%; and 15% with three replication per treatment (48 units total). Data on larval mortality and damage intensity were analyzed using RStudio via ANOVA and DMRT (α=5%). The BMP (15%) treatment demonstrated the highest efficacy, achieving 76.67% larval mortality while maintaining the lowest damage intensity of 0.20% on shallot plants. These results highlight BMP isolate at 15% concentration as the most promising biocontrol agent and support its further field evaluation as a sustainable alternative to chemical insecticides.

Abstract

The decrease in tomato plant production is caused by pest and disease attacks, one of which is the nematode Meloidogyne spp. Control measures still rely on synthetic nematicides, which can have negative effects on health, a broad spectrum of impact, microbial diversity, and resistance to attacks by Meloidogyne spp. Therefore, alternative control using biological agents that are resistant to the active ingredients of nematicides (carbofuran and dazomet) and have the ability to inhibit attacks by Meloidogyne spp. is needed. This study aims to test the resistance of Streptomyces spp. isolates to the active ingredients of synthetic nematicides, carbofuran and dazomet, and evaluate their effect on the mortality of Meloidogyne spp. nematodes. The method used is in vitro with the poisoned food technique and nematicidal activity testing against juvenile nematodes. The results show that the TMP isolate has better resistance than SP against carbofuran, with the second highest colony count of 11.47 × 10⁶ CFU/ml. Meanwhile, dazomet significantly inhibited the growth of Streptomyces spp. colonies. The mortality test showed that the TMP isolate was able to achieve a mortality rate of 59.01% in Meloidogyne spp. This proves the potential of Streptomyces spp. as a biological agent in nematode control and its resistance to nematicide residue active ingredients, making it an environmentally friendly alternative in agricultural practices. Keywords: Biological agent, Carbofuran, Dazomet, Meloidogyne spp., Streptomyces spp.

Abstract

Background: Streptomyces spp. are well known for their ability to produce antibiotic compounds with potential applications in plant disease management, but research in mangrove ecosystems tends to be limited. This study aims to explore and characterize Streptomyces isolates from the mangrove rhizosphere based on morphological characteristics and pathogenicity properties to find candidates as biocontrol agents. Methods: Morphological characterization was carried out macroscopically and microscopically, while hypersensitivity tests and soft rot tests were carried out to determine non-pathogenic properties. Results: A total of 24 isolates of Streptomyces sp. were successfully isolated with the morphological characteristics of circular colonies, filamentous and curved colony edges, convex, flat, raised, and umbonate colony elevations, aerial mycelial pigmentation with six color variations, and substrate mycelial pigmentation with six color variations. Microscopically, two types of spore chains were obtained, namely open spiral and closed spiral. All isolates were nonpathogenic based on the negative results of the hypersensitivity test and soft rot test. Conclusion: The mangrove rhizosphere provides a promising and morphologically diverse source of non-pathogenic Streptomyces isolates. Identification in this study was limited to morphological characterization; therefore, molecular analysis is needed to confirm the isolate species. These findings provide preliminary information as a basis for selecting isolates for further biological control studies.
