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

Bacterial leaf blight caused by the bacterium Xanthomonas oryzae is an important disease because it can cause severe damage and can infect the vegetative and generative phases of rice plants. This research was carried out to determine the spatial distribution of leaf blight using a geospatial approach and drone imagery. The results of this research indicate that the distribution of bacterial leaf blight disease on land at the research location tends to be higher in the northern part compared to the southern part of the land. The attack rate value at the end of the observation ranged between 20-68%. The distribution of leaf blight on land can be described through simulations using a geostatistical approach and confirmed by aerial imagery. Aerial imagery, especially binary imagery and kriging imagery, mutually confirm (crosscheck) the occurrence of leaf blight on land. Aerial images that are processed into binary images have the potential to be a remote sensing method that can make it easier to observe the distribution of diseases on land, especially leaf blight. Keywords: Campestris, Drone Imagery, Geospatial, Rice, Xanthomona.

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

Corn (Zea mays) production in Indonesia has experienced fluctuations due to infestations of the fall armyworm (Spodoptera frugiperda). Utilizing botanical pesticides derived from Ageratum conyzoides (Babandotan) and Mimosa pudica (Putri Malu) is a method to control the fall armyworm and maintain stable corn production. This study aims to identify the active compounds and determine the effective concentration of A. conyzoides and M. pudica extracts in reducing S. frugiperda populations. The research was conducted from June to November 2024 at the Pest Laboratory of the UPT Plant Protection Unit in Surabaya. The study was designed using a Completely Randomized Design with a single factor: different concentrations of plant extracts, replicated five times. Observed parameters included phytochemical tests, GC-MS compound screening, larval symptoms, mortality rate, pupae formation, and imago formation. The results showed that A. conyzoides and M. pudica extracts at the highest concentration (1%) significantly affected mortality rates, pupation, and adult emergence. Both extracts contained flavonoids, tannins, and triterpenoids, which effectively controlled S. frugiperda populations. Keywords: Bioinsecticide, Spodoptera frugiperda, Zea mays.

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

The diversity of natural enemies of insects is influenced by the availability of microhabitats and food sources, which can be increased through the use of refugia. Intensive use of pesticides in conventional agricultural systems has resulted in a decline in the diversity of natural enemies that play an important role in biological control of pests. This study aims to identify the types, roles, and populations of natural enemies of pests and determine the level of natural enemy diversity including the species diversity index, species evenness, species richness, and dominance in rice fields using integrated and conventional farming systems. Data collection methods were carried out through a combination of direct observation, insect nets, yellow traps, light traps, and identification of insect morphospecies using a digital microscope and supporting literature. The identification results showed 7 orders and 21 genera of natural enemies with a total of 4,679 individuals in integrated fields and 2,792 individuals in conventional fields. The species diversity index (H’=2.11), evenness (E’=0.69), species richness (R’=2.37), and dominance (C’=0.18) indicated that the integrated system was more supportive of biodiversity. Ecological engineering through refugia has been shown to increase the population diversity of natural enemies, thereby strengthening biological control in rice ecosystems.
