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

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

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.
