Antifungal volatiles produced by some antagonistic agents can be useful in biological control approach of this pathogen. Some yeasts have been reported to produce antifungal volatiles and may have the potency as antagonistic agents against fungal pathogens. This research was aimed to determine the morphological characteristics of the yeast isolates and their ability to suppress <em>C. coffeicola</em> by producing antifungal volatiles. The yeasts were isolated from coffee leaves and berries grown in several location at Kecamatan Cilengkrang, Kabupaten Bandung and Kecamatan Jatinangor, Kabupaten Sumedang. The research was started by isolation of yeasts and followed by morphological characterization of yeasts’ colony. The potency of the volatiles produced by the antagonistic isolates were tested <em>in vitro</em> using double dish system. As many as 52 yeast isolates were obtained. The dominant colors of the yeasts colonies on PDA were white, cream, and orange, with smooth, serrated, and filamentous edges. The colony shapes were round to irregular. The microscopic observation showed that the cells were round, ovate, and elongated, with the size ranged around 2.59-18.13 × 1.23-7.77 µm. Those yeasts isolates were able to suppress the growth of<em> C. coffeicola</em> by the activity of antifungal volatile compound, with the inhibition level of 11.85% to 79.26%. The results showed that all the isolates were capable to inhibit the <em>in vitro</em> growth of <em>C. coffeicola</em>.</p>2024-01-02T00:00:00+07:00Copyright (c) 2024 Jurnal Fitopatologi Indonesiahttps://journal.ipb.ac.id/index.php/jfiti/article/view/50994Perlakuan Panas Kering dan Ekstrak Rimpang Lengkuas terhadap Benih Kedelai Terinfeksi Xanthomonas axonopodis2024-02-28T21:28:26+07:00Qonitah Fauziyahfauziyah1028@gmail.comEvan Purnama Ramdanevan_ramdan@staff.gunadarma.ac.idRisnawati Risnawatirisnawati@staff.gunadarma.ac.idFitri Yuliantifitri_yulianti@staff.gunadarma.ac.id<p><strong>Dry Heat Treatment and Galangal Rhizome Extract on Soybean Seeds Infected with<em> Xanthomonas axonopodis</em></strong></p> <p>Soybean (Glycine max) is one of the sources of vegetable protein whose demand continues to increase. One of the main obstacles in soybean cultivation is the bacterial pustule seed-borne disease caused by <em>Xanthomonas axonopodis</em> pv. <em>glycine.</em> This study aimed to evaluate dry heat treatment and galangal rhizome extract on the suppression of <em>X. axonopodis</em> pv. <em>glycine</em> population and vigor of soybean seeds infected with the bacteria. The study was arranged in a completely randomized design. The first experiment was dry heat treatment at 45 ℃ with heating times of 6, 12, and 24 hours, and control without heating. The second experiment was soaking the seeds for one hour in galangal rhizome extract with concentrations of 25%, 20%, and 15%, and the control (water). The variables observed were bacterial population, germination, vigor, and viability of the seeds. The results showed that heat treatment and galangal rhizome extract had a significant effect on reducing the population of <em>X. axonopodis</em> carried by soybean seeds. Treatment of soybean seeds with dry heat for 24 hours caused the seeds to be free of <em>X. axonopodis</em>, but seed germination and vigor decreased. While seed treatment with 25% galangal rhizome extract caused the <em>X. axonopodis</em> population to decrease to 7.0 × 102 cfu mL<sup>-1</sup>, while not affecting soybean vigor and viability. The results indicate that dry heat treatment has better potential than galangal rhizome extract in eliminating <em>X. axonopodis</em> in soybean seeds. However, because heat treatment has a negative impact on seed germination, it is necessary to find the optimal heating temperature and time to suppress <em>X. axonopodis</em> populations without reducing seed viability.</p>2024-01-18T00:00:00+07:00Copyright (c) 2024 Jurnal Fitopatologi Indonesiahttps://journal.ipb.ac.id/index.php/jfiti/article/view/49682Perbanyakan Nematoda Daun Aphelenchoides fragariae pada Biakan Cendawan 2024-02-28T21:29:20+07:00Fitrianingrum Kurniawatifitrianingrum@apps.ipb.ac.idSupramanasupramana@apps.ipb.ac.idSri Hendrastuti Hidayatsrihendrastuti@apps.ipb.ac.idEfi Toding Tondokettondok@apps.ipb.ac.idHeriyanto Syafutrafitrianingrum@apps.ipb.ac.id<p><strong>Mass Rearing of Foliar Nematode <em>Aphlenchoides fragariae</em> on Fungal Culture</strong></p> <p>This research investigated the in vitro cultivation of the foliar nematode <em>Aphelenchoides fragariae</em>, which can feed on both plants and fungi. As there was no prior information available in Indonesia, this study aimed to establish an efficient method for mass rearing, thereby supporting future research. Five fungal cultures i.e. <em>Alternaria porri</em>, <em>Fusarium oxysporum</em>, <em>Botrytis cinerea</em>, <em>Pythium</em> sp., and <em>Rhizopus</em> sp. grown in potato dextrose agar were evaluated as potential growing media at three different temperatures: 16, 28, and 37 ℃. Nematodes were surface-sterilized with streptomycin sulfat 0.1% before being introduced into the fungal cultures. Results showed that <em>A. porri</em> was the most favourable culture for <em>A</em>. <em>fragariae</em> reproduction, particularly at 28 ℃. Under these conditions, the average final population reached 407.8 nematodes per petri dish. Notably, <em>A. fragariae</em> failed to thrive at 37 ℃ in all tested fungal media. This suggests that the optimal temperature for its reproduction ranges between 16 and 28 ℃. This study provides valuable insights into the <em>in vitro</em> cultivation of <em>A. fragariae</em>, paving the way for further research utilizing this nematode species.</p>2024-01-20T00:00:00+07:00Copyright (c) 2024 Jurnal Fitopatologi Indonesiahttps://journal.ipb.ac.id/index.php/jfiti/article/view/51044Isolasi Bakteri Filosfer Berpotensi sebagai Penambat Nitrogen dan Deteksi in Vitro Kemampuannya dalam Menghambat Pertumbuhan Colletotrichum 2024-02-28T21:26:16+07:00Fitri Widiantinifitri.widiantini@unpad.ac.idFitika Syahnurfitika18001@mail.unpad.ac.idYusup Hidayatyusup.hidayat@unpad.ac.idEndah Yuliaendah.yulia@unpad.ac.id<p><strong>Isolation of Potential Nitrogen-Fixing Phylloplane Bacteria and <em>in Vitro</em> Detection of Their Ability to Inhibit the Growth of <em>Colletotrichum </em></strong></p> <p>Anthracnose is one of the significant diseases in chili plants caused by <em>Colletotrichum</em> spp., with potential yield losses of up to 100%. The negative impact of fungicide use forces the search for biocontrol agents as part of environmentally friendly disease management. One of the sources where these biocontrol agents can be found is in the phyllosphere. This experiment aimed to obtain antagonistic bacteria from the phyllosphere of healthy chili plants that have the potential to be developed as biocontrol agents and potentially increase the nutrition uptake through nitrogen-fixation. Healthy chili plants were obtained from red chili plantations in Cijambu Village and Nanggerang Village, Sumedang Regency, West Java. Isolation using Nitrogen-free media and screening for antagonistic activity resulted in the isolation of eight bacterial strains, namely strains CJB1, CJB2, CJB3, CJB4, CJB5, NGR1, NGR2, and NGR3. The antagonistic tests on these eight bacterial strains were then conducted against various <em>Colletotrichum</em> spp. strains from different chili cultivation centers in Garut, Lembang, Sumedang, and Jatinangor. The testing was carried out using a dual-culture method followed by the examination of volatile compound activity using the double compartment method. The results showed that phyllosphere bacteria NGR1, CJB1, and CJB5 consistently demonstrated abilities to inhibit the growth of four <em>Colletotrichum</em> spp. strains, both directly through antagonistic tests and based on the volatile anticendawan compound activity produced by these bacterial strains. Malformations in the mycelium of <em>Colletotrichum</em> spp. were also detected when the pathogen was directly exposed to phyllosphere bacteria or their volatile compounds. This experiment indicates that phyllosphere bacteria that potentially capable of fixing nitrogen also have the potential to be developed as biocontrol agents for <em>Colletotrichum</em> spp.</p>2024-02-13T00:00:00+07:00Copyright (c) 2024 Jurnal Fitopatologi Indonesiahttps://journal.ipb.ac.id/index.php/jfiti/article/view/51249Begomovirus yang Berasosiasi dengan Gejala Mosaik Kuning pada Tanaman Terung di Bengkulu 2024-02-29T12:19:48+07:00Ade Nabillahmimi_sutrawati@unib.ac.idIntan Suryani Alamriamimi_sutrawati@unib.ac.idIcha Kurnia Nanda Sarimimi_sutrawati@unib.ac.idmimi sutrawatimimi_sutrawati@unib.ac.idHendri Bustamamhendribustamam@unib.ac.id<p>Eggplant (<em>Solanum melongena</em>) is a horticultural crop that has high economic value and is widely cultivated. One of the obstacles to eggplant cultivation is virus infection that causes diseases. In several eggplant fields in Bengkulu, systemic symptoms of yellow mosaic were found which were similar to <em>Begomovirus</em> infection in chilies. Research was conducted to detect and identify <em>Begomovirus</em> as the causal agent of yellow mosaic symptoms on eggplant plants in Bengkulu and its association with betasatellites. Samples were taken by purposive sampling from eggplant fields in Bengkulu City, Central Bengkulu Regency, North Bengkulu Regency, Kepahiang Regency, and Rejang Lebong Regency. Virus detection was carried out by PCR method using <em>Begomovirus</em> universal primers and betasatellite specific primers followed by confirmation of virus identity by DNA sequencing. PCR using universal <em>Begomovirus</em> and betasatellite primers was successfully amplified DNA fragments measuring ±912 bp and ±1300 bp, respectively from leaf samples with symptoms of yellow mosaic, leaf malformation and thickening of leaf veins. Based on DNA sequencing, samples from North Bengkulu and Kepahiang showed the highest homology 99% with <em>Tomato yellow leaf curl Kanchanaburi virus</em> (TYLCKaV) from Indonesia, Malaysia and Thailand. These findings are the first reports of TYLCKaV infection and its association with <em>Begomovirus</em> betasatellites on eggplant in Bengkulu.</p>2024-02-26T14:58:17+07:00Copyright (c) 2024 Jurnal Fitopatologi Indonesiahttps://journal.ipb.ac.id/index.php/jfiti/article/view/54158ERRATUM2024-02-29T12:19:41+07:00Editors Jurnal Fitopatologi Indonesiajurnal.fitopatologi@apps.ipb.ac.id<p><strong>Erratum </strong>to:</p> <ol> <li class="show">Hartati S, Meliansyah R, Mayanti T. 2024.
