Abstract

Patogen Ralstonia syzygii subsp. indonesiensis adalah penyebab penyakit layu bakteri pada tanaman tomat. Patogen ini sulit dikendalikan karena kemampuannya bertahan dalam sisa bahan inang, tanah, dan dapat menyebar dengan mudah melalui aliran air, serta menginfeksi jaringan tanaman secara sistemik. Belum ada pestisida kimia yang efektif untuk mengendalikan patogen layu bakteri. Oleh karena itu, alternatif pengendalian yang dipilih ialah dengan menggunakan bakteri endofit dan asam salisilat. Dua jenis bakteri endofit, yaitu Arthrobacter sp. dan Bacillus thuringiensis, serta asam salisilat digunakan dalam penelitian secara tunggal ataupun kombinasi untuk mengevaluasi potensinya dalam menginduksi ketahanan tanaman tomat dalam menekan penyakit layu bakteri R. syzygii subsp. indonesiensis. Penelitian dilakukan dengan rancangan acak lengkap non faktorial dengan 14 perlakuan terdiri atas perlakuan tunggal dan kombinasi. Setiap perlakuan terdiri atas tiga unit tanaman dan tiga ulangan. Hasil penelitian menunjukkan bahwa kombinasi Arthrobacter sp. dan asam salisilat yang diaplikasikan satu kali seminggu (ABAS1) merupakan perlakuan yang paling efektif untuk menginduksi ketahanan tomat. Hal ini tampak pada periode inkubasi yang paling lama, rendahnya insidensi dan keparahan penyakit, meningkatnya aktivitas enzim peroksidase, polifenoloksidase, dan jaringan xilem tidak dominan terkolonisasi patogen pada pengamatan histopatologi.

Abstract

Penyakit pucuk putih pada padi yang disebabkan oleh Aphelenchoides besseyi merupakan penyakit tergolong baru dan telah tersebar di Indonesia. Penggunaan varietas tahan merupakan salah satu cara terbaik untuk mengendalikan A. besseyi. Namun, belum ada informasi terkait ketahanan varietas padi terhadap A. besseyi di Indonesia. Sembilan varietas padi diuji respons ketahanannya terhadap A. besseyi dengan menggunakan inokulum sebanyak 500 ekor nematoda per tanaman. Nematoda A. besseyi diinfestasikan pada fase pembungaan dengan cara menyemprotkan suspensi nematoda ke bagian malai dan diamati panjang malai, jumlah bulir, jumlah bulir bernas dan hampa, berat 100 bulir bernas, jumlah nematoda, dan ekspresi gen PBZ1 padi. Deteksi gen ketahanan PBZ1 dilakukan dengan one step reverse transcription-polymerase chain reaction (RT-PCR) menggunakan primer spesifik PBZ1F dan PBZ1R. Berdasarkan parameter hasil panen, populasi A. besseyi, dan ekspresi gen PBZ1, respons ketahanan varietas padi terhadap infestasi A. besseyi dibagi menjadi tiga kategori ketahanan, yaitu tahan (‘Ciherang’, ‘Utri Merah’, dan ‘Utri Rajapan’), toleran (‘Inpago 7’, ‘IPB 3S’, ‘Prima’, dan ‘Situ Bagendit’), dan rentan (‘Inpara 3’ dan ‘Inpara 4’). Infestasi A. besseyi menginduksi ekspresi gen PBZ1 pada varietas uji dengan intensitas berbeda tergantung tingkat ketahanan varietas. Varietas ‘Ciherang’, ‘Inpago 7’, ‘Situ Bagendit’, ‘Utri Merah’, dan ‘Utri Rajapan’ menunjukkan ekspresi gen PBZ1 tinggi baik sebelum maupun setelah infestasi A. besseyi. Intensitas ekspresi gen PBZ1 yang tinggi sebelum infestasi A. besseyi menunjukkan varietas ini merupakan sumber potensial varietas tahan terhadap A. besseyi. Hasil penelitian menunjukkan ada korelasi antara tingginya ekspresi gen PBZ1 dengan ketahanan varietas padi terhadap A. besseyi.

Abstract

Basal stem rot (G. boninense) is one of the most important diseases in oil palm. As biocontrol agents, Trichoderma spp. and arbuscular mycorrhizal fungi (AMF) have been reported to inhibit the growth of G. boninense. Nevertheless, the effectiveness of those biocontrol agents is unstable due to less appropriate formulation and application. Biofungicide formulation affects the effectiveness in controlling plant diseases, the ability to proliferate and survive in the environment, the period of storage, and reduces preparation time and application cost. This research aimed to develop the formulation of Trichoderma spp., and AMF to control G. boninense. Trichoderma spp. The active ingredient has been mass-produced in millet formulated with carriers: T1 using rice bran, while T3 was combined with rice bran and oil palm empty fruit bunches (EFB) compost. AMF active ingredient has been mass producted in shorgum root, and formulated with carrier, CMA1 using zeolite. While, CMA2 combined zeolite with EFB compost. AMF applications were on seed planting, Trichoderma spp. applications were on three months seedlings. Plant material used was DXP (76 × 36.11), which is susceptible to G. boninense. Disease progress was observed from latent period, disease incidence, disease severity, infection rate (r), area under disease progress curve (AUDPC), and the AMF-Trichoderma association with plant oil palm root. CMA2 and T3 formulation showed the best result to reduce disease severity and insidence. Therefore, CMA2 + T3 was the best combination of formulation for controlling oil palm basal stem rot disease based on disease progress.

Abstract

Penyakit darah yang disebabkan oleh Ralstonia solanacearum Phylotype IV merupakan penyakit penting pada pisang yang menyebabkan kehilangan hasil hingga 100%. Bakteri R. solanacearum mengekspresikan gen virulensi melalui mekanisme quorum sensing (QS) dengan menggunakan asil homoserin lakton (AHL) sebagai autoinducer. Enzim AHL laktonase diproduksi oleh bakteri dan memiliki potensi sebagai agens biokontrol bakteri patogen melalui anti-QS. Tujuan dari penelitian ini ialah memperoleh isolat bakteri endofit penghasil AHL laktonase untuk pengendalian R. solanacearum pada tanaman pisang. Tahapan penelitian mencakup isolasi dan seleksi bakteri endofit asal tanaman pisang sebagai penghasil AHL laktonase dengan bioassay maupun molekuler, uji keefektifan isolat bakteri dalam menekan faktor virulensi R. solanacearum, uji keefektifan pengendalian R. solanacearum in planta, dan identifikasi molekuler isolat bakteri potensial. Isolasi bakteri endofit berhasil dilakukan dari sampel pisang asal Bogor di tiga kecamatan, yaitu Cisarua, Dramaga, dan Jonggol yang terdiri atas lima jenis pisang masing-masing menghasilkan 152, 204, dan 130 isolat bakteri endofit. Uji lebih lanjut menggunakan Chromobacterium violaceum sebagai bioindikator menunjukkan lima isolat dengan aktivitas anti-QS. Deteksi gen aiiA dengan PCR menggunakan primer spesifik menunjukkan bahwa kelima isolat memiliki amplikon berukuran 753 pb dan telah dikonfirmasi melalui sekuensing sebagai gen aiiA. Kelima isolat bakteri tersebut CBP1, DBT17, DBT7, DBK2, dan CBN13 mampu menekan pembentukan ekstraseluler polisakarida (EPS) yang dihasilkan R. solanacearum dengan persentase penekanan masing-masing sebesar 75.67%, 90.81%, 87.67%, 92.72%, 81.08%, dan mampu menghambat gejala layu sebagai salah satu gejala penyakit darah pada tanaman pisang. Hasil perunutan gen aiiA menunjukkan bahwa kelima isolat homolog dengan Bacillus cereus, B. thuringiensis, B. substilis, B. amyloliquefaciens.

Abstract

Application of Bamboo Root Plant Growth Promoting Rhizobacteria and Local Microorganisms in Soybean to Control of Bacterial Pustule (Xanthomonas axonopodis pv. Glycines) Xanthomonas axonopodis pv. glycines (Xag) is a pathogenic bacterium that causes pustule disease in soybean plants, leading to significant levels of damage. One of the biological control efforts against this pathogen involves the use of plant growth-promoting rhizobacteria (PGPR) and local microorganisms (MOL). This study aims to determine the effect of PGPR and MOL applications on enhancing plant growth and controlling bacterial pustule disease. The Xag JB12 isolate from the University of Jember was used as the inoculum source. PGPR from bamboo roots and MOL from fruit and vegetable waste were used as antagonistic agents against the Xag JB12 isolate. The experimental study was designed using four treatments (control, PGPR application, MOL application, and PGPR + MOL application). PGPR/MOL application was carried out through seed soaking and drenching. The results showed that the MOL treatment exhibited the lowest disease severity, which was 20.02%. The MOL treatment showed the highest disease progression rate, but the smallest area under the disease progress curve (AUDPC) compared to other treatments. The study also found that all treatments had no significant effect on plant height and leaf number variables.

Abstract

Penyakit tristeza yang disebabkan oleh citrus tristeza virus (CTV, genus Closterovirus, famili Closteroviridae) merupakan salah satu penyakit penting pada tanaman jeruk di dunia, termasuk di Indonesia. Hingga kini, informasi dan studi terkait CTV di Indonesia masih terbatas. Penelitian ini bertujuan untuk mengetahui status terkini infeksi CTV di Provinsi Sulawesi Tenggara. Survei dan pengambilan sampel dilakukan secara purposive sampling di empat kabupaten. Deteksi dan identifikasi virus dilakukan dengan teknik double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA), reverse transcription polymerase chain reaction (RT-PCR), dan analisis perunutan nukleotida. Hasil DAS-ELISA menunjukkan bahwa semua sampel dengan berbagai variasi gejala dari empat kabupaten terkonfirmasi positif terinfeksi CTV dengan nilai  titer virus yang beragam. RT-PCR dengan primer spesifik berhasil mengonfirmasi keberadaan CTV dari semua sampel dengan teramplifikasinya DNA berukuran 630 pb. Analisis sekuen  dan  filogeni menunjukkan bahwa isolat CTV asal Sulawesi Tenggara memiliki kemiripan tertinggi (97.9%) dengan isolat CTV asal India (MT498411.1) dan mengelompok satu grup dengan isolat asal India (MT498411.1), Jepang (U56902.1), dan Cina (MZ692538.1). Hasil penelitian ini mengonfirmasi penyebaran CTV pada empat kabupaten di Sulawesi Tenggara. Data molekuler diharapkan menjadi basis data untuk studi epidemiologi molekuler dan strategi pengendalian penyakit tristeza di Indonesia.

Abstract

The Potential of Plant Growth-Promoting Bacteria to Suppress Infection of Cucumber mosaic virus on Cucumber Plants Mosaic disease caused by Cucumber mosaic virus (CMV) is one of the main diseases of cucumber plants, and is economically important. Plant growth-promoting bacteria (PGPB) are plant root organisms currently being developed as biological agents. This research aims to obtain the best PGPB that can suppress the development of CMV in cucumber plants. This research used a randomized block design with nine treatments and five replications. The treatments consisted of several isolates of PGPB (Serratia marsescens AR1, Alcaligenes faecalis AJ14, Stenotrophomonas pavanii KJKB 5.4, Pseudomonas fluorescens LPK1–9, Bacillus cereus AJ 34, and S. maltophilia LMTSA 5.4), orthohydroxybenzoic acid (salicylic acid), positive control, and negative control. Application of PGPB was conducted through seed treatment of cucumber seeds for 15 minutes before planting. The mosaic virus was mechanically inoculated on cucumber cotyledons seven days after planting. The variables observed were the development of mosaic disease and the growth of cucumber plants. Virus detection using specific primer pair CMV-IF/CMV-IR showed that the virus that infected cucumber plants had 98.3% similarity to the CMV isolate originating from India with accession number KJ874248.1. Pseudomonas fluorescens LPK1-9 is the best bacteria for slowing the incubation period, reducing the percentage of infected leaves, and reducing the severity of mosaic disease on cucumber plants. None of tested PGPB isolates that has the potential to increase the growth of CMV-infected cucumber plants. Therefore, further studies are needed on the effectiveness of the PGPB, such as improving how PGPB is applied.

Abstract

The Role of Trichoderma spp. as a Biocontrol Agent of Damping Off Disease and Soybean Biostimulant   Domestic demand for soybeans in Indonesia continues to increase each year, yet the average production has declined. To meet national needs, the government must even import soybeans. One of the causes of low soybean production is damage from plant pests and diseases, particularly damping-off caused by Sclerotium rolfsii, which can lead to total plant death under severe infection. One promising, environmentally friendly, and cost-effective approach to disease management is the use of biological control agents such as Trichoderma spp., which function not only as biocontrol agents but also as biostimulants. This research was conducted at the Plant Pest and Disease Laboratory, Faculty of Agriculture Brawijaya University and Central Laboratory of BALITKABI for in vitro experiments and in vivo study located at a greenhouse of Agriculture Experimental Land Brawijaya University, Jatimulyo, Lowokwaru, Malang. A completely randomized design was used with five treatments and five replications. Applications of Trichoderma harzianum and T. asperellum, either individually or in combination, successfully reduced the incidence and severity of damping-off disease by 14% to 26.6% under field conditions. These treatments also increased the total phenolic content of the plants, indicating enhanced resistance, thus supporting the role of Trichoderma as an effective biocontrol agent. In addition, the combined application of Trichoderma species significantly increased the number of soybean leaves, indicating a biostimulant effect.
