The main diseases of tomato caused by wilt bacteria (Ralstonia solanacearum) and root knot nematodes (Meloidogyne spp.) may cause significant yield losses and need to be managed. Recently, biocontrol approach especially using endophytic bacteria has been developed to control plant pathogens. This research was aimed to obtain endophytic bacteria from 2 species of mangrove, which effectively controlled root knot nematode and wilt bacteria. A total of 843 endophytic bacteria were successfully isolated from 2 species of mangroves. The bacteria isolates were further subjected for biosafety assay. The results of the test showed that 403 endophytic bacteria gave negative reaction in hypersensitive and hemolytic tests. Furthermore, 19 isolates effectively suppressed the growth R solanacearum and killed Meloidogyne in in vitro test. Physiological test showed that 14 and 11 isolates of the bacteria were able to produce protease and chitinase, respectively. This research provides a new information that endophytic bacteria from mangrove has a potency as a biocontrol agents.

Detection and Identification of Aphelenchoides besseyi from Rice SeedsAphelenchoides besseyi is an important plant parasitic nematode on rice and causes yield loss up to 54%. The nematodes are able to survive for 8 months to 3 years after harvest and can be transmitted through seeds. The research was conducted to determine infestation of A. besseyi on seeds of five rice cultivars, namely Pak Tiwi 1, IR64, Ciherang, IPB 3S, and SL 8 SHS; and to identify A. besseyi by morphological and molecular techniques using polymerase chain reaction (PCR), and nucleotide sequensing. The nematodes were extracted from 5 g seeds of each cultivar by modified Baermann funnel method. Morphological identification was done by observing semipermanent slide of adult nematodes. Molecular identification by PCR used universal primers to amplify ITS rDNA followed by nucleotide sequencing. The result showed that A. besseyi were found on 5 rice cultivars in varies numbers. A. besseyi has specific morphological character, i.e. it has 2–4 mucro (tail tip) arranged in a star shaped that can be distinguished from other species. DNA fragments with approximately 830 bp in length was successfully amplified. Further nucleotide sequence analysis showed that A. besseyi Indonesia (isolate Pak Tiwi 1) had the higest homology level of 98.1% with A. besseyi isolat India Drr Ab 1 and Kolkata, 98.0% with India Hyderabad, 97.8% with China HB, 97.7% with Taiwan HW, and 97.5% with Cina AB11.

Rhizoctonia solani merupakan salah satu patogen penting penyebab penyakit hawar seludang pada tanaman padi. Patogen ini termasuk yang sulit dikendalikan karena bersifat kosmopolit, mampu bertahan di dalam tanah, dan memiliki kisaran inang yang banyak. Pengendalian secara biologi dengan bakteri endofit merupakan salah satu alternatif yang potensial karena kemampuannya hidup di dalam jaringan tanaman tanpa menimbulkan gejala penyakit dan dapat meningkatkan pertumbuhan serta ketahanan tanaman. Tujuan penelitian ini ialah mengeksplorasi bakteri endofit dari bagian batang akar dari tiga jenis tumbuhan paku yang berbeda, yaitu Salvinia molesta (paku air), Pteris ensiformis (paku terestrial), dan Drymoglossum pilosolloides (paku epifit) dan mengevaluasi potensinya sebagai agens hayati R. solani dan pemacu pertumbuhan tanaman. Isolasi bakteri dilakukan pada medium tripsic soy agar (TSA) dan nutrient agar (NA). Isolat bakteri dimurnikan dan diuji keamanan hayati dengan uji hipersensitifitas dan hemolisis. Hasil penelitian diperoleh 178 isolat bakteri endofit dan sebanyak 88 isolat menunjukkan reaksi negatif pada uji hipersensitisfitas dan uji hemolisis. Selanjutnya, isolat tersebut diuji dual test secara in vitro terhadap R. solani dan didapatkan 4 isolat bakteri endofit (APE15, APE22, APE33, dan APE35) dengan daya hambat dari 27–76% pada medium TSA, agar-agar dekstrosa kentang (ADK), dan TSA + ADK. Hasil uji pertumbuhan empat isolat terhadap benih padi varietas Situ Bagendit menunjukkan bahwa bakteri endofit mampu meningkatkan persentase perkecambahan padi 4.9% – 48.8%, meningkat panjang akar padi 68.3%–95.4%, panjang pucuk 53.2%–87.3%, bobot segar 49.07%–90.65%, dan bobot kering 48.1%–87.3%. Hasil ini menunjukkan bahwa tumbuhan paku mengandung beberapa bakteri endofit yang dapat dikulturkan dan memiliki senyawa antimikrob yang efektif, serta dapat digunakan sebagai sumber agens hayati terhadap patogen R. solani dan pemacu pertumbuhan tanaman.

Effectivity of Single Isolates, Mixtures, and Consortium of Endophytic Bacteria Against Fusarium solani and Meloidogyne spp. in Vitro Fusarium solani and Meloidogyne spp. is known as pathogens associated with pepper yellow disease. The use of endophytic bacteria for controlling this disease needs to be evaluated. Therefore, this study was conducted with the aim of evaluating the biocontrol activity of endophytic bacterial isolates applied singly (B. siamensis and B. velezensis), mixed (B. subtilis and B. wiedmannii) and consortium (PTM3) in suppressing F. solani and Meloidogyne spp. in vitro. Research methods included the isolation of F. solani and extraction of Meloidogyne spp. from the roots of infected plant, pathogenicity test, dual culture and mortality test, as well as physiological assay of endophytic bacterial isolates. The isolates of F. solani and Meloidogyne spp. proven to be pathogenic in pepper seedlings and causing yellow symptoms. Four isolates of endophytic bacteria were able to inhibit mycelium growth of F. solani. The highest inhibition on TSA medium was shown by a single isolate of B. siamensis, i.e. 57.25%; while on PDA medium was shown by mixed isolates of B. subtilis and B. wiedmannii, i.e. 56.47%. Application of B. velezenziz caused the highest mortality rate of Juvenile larval 2 Meloidogyne spp., i.e. 75.24%. Both B. siamensis and B. velevenzis isolates showed protease and cellulase activity; while mixed isolates of B. subtilis and B. wiedmannii and the PTM3 consortium isolates showed chitinase, protease and cellulase activity.
