Ginger (Zingiber officinale Rosc.) is a type of rhizome plant that has high potential to be developed in Indonesia as a medicinal plant or spice. Inhibiting factors in ginger production is Ralstonia solanacearum which causes bacterial wilt disease. Rhizobacteria is a potential biological agent to control the disease. It is necessary to review from various study on rhizobacteria both the use of antagonistic bacteria singly or in a consortia. Aimed to analyze various sources of scientific literature regarding the potential of antagonistic bacteria singly or consortia compared to synthetic bactericides in controlling of R. solanacearum. The results showed that three recommended antagonist bacteria were found, namely Pseudomonas fluorescens, Bacillus subtilis, and Bacillus thuringiensis. which has the potential to control bacterial wilt disease. The rhizobacterial consortia are more effective as a sustainable, safe and environmentally friendly control on bacterial wilt disease with a percentage of disease incidence 10%. In addition, the rhizobacterial consortia are three and six times more effective than the single antagonistic bacteria and bactericides respectively.

ABSTRACT<br />Bacterial wilt caused by Ralstonia solanacearum is one of the most<br />destructive diseases on ginger. The aim of this study was to evaluate the<br />potential use of five different medicinal plants extracts (Acalypha indica,<br />Andrographis paniculata, Centella asiatica, Curcuma xanthorrhiza, and<br />Spinosa oleracea) as sources of plant resistance inducer compounds<br />(elicitor) against bacterial wilt disease on ginger. Salicylic acid was used<br />as a standard synthetical compound, as well as, water as a control<br />treatment. The study was conducted at the Indonesian Spice and Medicinal<br />Crops Research Institute, Bogor in 2010-2011. Research was conducted in<br />Completely Randomized Design that consisted of 7 treatments, 3<br />replicates, and 10 plants/ replicate. Ginger seeds were planted in a mixture<br />of soil and manure in polybags. One-month old ginger plants were sprayed<br />or drenched with each of the medicinal plant extract before and after R.<br />solanacearum inoculation. This experiment indicated that the medicinal<br />plant extracts tested were effective in reducing wilt disease incidence on<br />ginger. Their effectiveness varied depended on the plant species and the<br />application method used. Among those five medicinal plant extracts tested,<br />A. indica, A. paniculata, and C. xanthorrhiza were the most stable and<br />effective.  Their  effectiveness  were  comparable  with  the  standard<br />compound of salicylic acid. This finding indicated that A. indica, A.<br />paniculata, and C. xanthorrhiza were potentially used as sources of<br />botanical elicitor compounds. The use of those medicinal plant extracts as<br />sources of botanical elicitor, hopefully could increase ginger resistance and<br />rhizome production, as well as reduce the use of synthetic pesticides.<br />Keywords:  Medicinal  plant  extracts,  elicitor  compounds,  induced<br />resistance, ginger, wilt disease<br />ABSTRAK<br />Layu  bakteri  yang  disebabkan  oleh  Ralstonia  solanacearum<br />merupakan salah satu penyakit yang merusak tanaman jahe. Penelitian ini<br />bertujuan untuk mengevaluasi potensi lima jenis ekstrak tanaman obat<br />(akar kucing, sambiloto, pegagan, temulawak, dan bayam duri) sebagai<br />sumber senyawa penginduksi ketahanan (elisitor) tanaman jahe terhadap<br />penyakit layu. Pada penelitian ini digunakan asam salisilat sebagai<br />senyawa sintetik standard dan air sebagai perlakuan kontrol. Penelitian<br />dilaksanakan di Balai Penelitian Tanaman Rempah dan Obat, Bogor pada<br />tahun  2010-2011.  Percobaan  dilaksanakan  dengan  menggunakan<br />rancangan acak lengkap yang terdiri atas 7 perlakuan, 3 ulangan, dan 10<br />tanaman/ ulangan. Rimpang jahe ditanam pada media campuran tanah dan<br />pupuk kandang di dalam polibeg. Jahe umur satu bulan disemprot atau<br />disiram dengan ekstrak tanaman obat sebelum dan setelah diinokulasi R.<br />solanacearum. Hasil penelitian mengindikasikan bahwa ekstrak tanaman<br />obat yang diuji efektif dapat mengurangi kejadian penyakit layu pada<br />tanaman jahe. Efektivitas dari tanaman tersebut bervariasi tergantung dari<br />spesies tanaman dan cara aplikasinya. Diantara kelima tanaman obat yang<br />diuji, akar kucing, sambiloto, dan temulawak paling stabil dan efektif<br />dalam mengurangi terjadinya penyakit layu. Efektivitas dari ketiga<br />tanaman obat tersebut sama dengan senyawa asam salisilat. Hasil<br />penelitian menunjukkan bahwa akar kucing, sambiloto, dan temulawak<br />berpotensi untuk digunakan sebagai sumber senyawa elisitor botanis.<br />Penggunaan  ekstrak tanaman  obat  sebagai  sumber  elisitor  botanis<br />diharapkan dapat meningkatkan ketahanan tanaman dan produksi jahe<br />serta mengurangi penggunaan pestisida sintetik.<br />Kata kunci: Ekstrak tanaman, senyawa elisitor, induksi ketahanan, jahe,<br />penyakit layu.

<p>Wilt disease of <em>Solanaceae</em> caused by <em>Ralstonia solanacearum</em> reduce the crop quality and negatively affect the crop product. The objective of this research was to discover of endophytic bacteria formulation that effectively decreases bacterial which cause wilt disease on <em>Solanaceae</em>. The research consisted of purification of <em>Ralstonia solanacearum</em>, endophytic bacteria were obtained from the sample and the screening of endophytic bacteria using this following assay: antagonist assay, seedling assay and <em>in planta</em> assay. The results showed that in antagonist assay, the bacterial isolate code PS<sub>1</sub>, PS<sub>2</sub>, and PS<sub>8 </sub>could inhibit growth of <em>R. solanacearum. </em>From the seedling assay, it obtained that all of the isolates increased of percentage of germination, seed coating and powder formulation can decrease disease incidence of bacterial wilt disease.</p>

Bacterial wilt disease (Ralstonia solanacearum) is one of the most important diseases in Solanaceae, including chili. Biological control is one of environmentally-friendly method for controlling plant diseases. Microbes that are potential as biological control agents include bacterial endophytes and bacteria that are usually used as biofertilizer. This paper discusses the result of the study that examined the abilities of endophytic and biofertilizing bacteria solely or in combination to suppress bacterial wilt disease (R. solanacearum). The endophytic bacteria isolates tested were Lysinibacillus sp. and Bacillus subtilis, while biofertilizing bacteria used were N-fixing bacteria (Azotobacter chrococcum) and P-solubilizing bacteria (Pseudomonas cepacea). The results showed that the endophytic bacteria, biofertilizing bacteria and their combination inhibited wilt disease incidence in chili by 46.7-80 %. The highest disease suppression (80 %) showed by the endophytic bacteria, B. subtilis. This endophyte was also able to promote a significant chili growth. Keywords: Ralstonia solanacearum, Endophytic bacteria, Biofertilizer, Biological control, Chili.

(1) Background: Ralstonia solanacearum causes tomato bacterial wilt disease, one of the most serious tomato diseases. As the combination of Trichoderma virens (Tvien6) and Bacillus velezensis (X5) was more effective at controlling tomato bacterial wilt disease than a single agent, we investigated the synergistic effect of Tvien6 and X5 in controlling this disease; (2) Methods: The disease incidence, plant heights and weights, relative chlorophyll content (SPAD values), defensive enzymes (PPO, POD, and SOD) activities, and metabolome were estimated among four treatment groups (BR treatment, X5 + R. solanacearum (RS-15); TR treatment, Tvien6+ RS-15; TBR treatment, Tvien6 + X5 + RS-15; and R treatment, RS-15); (3) Results: The R treatment group had the highest disease incidence and lowest plant heights, plant weights, SPAD values, defensive enzyme activities, and D-fructose and D-glucose contents; the TBR treatment group had the lowest disease incidence and highest plant heights, plant weights, SPAD values, defensive enzyme activities, and D-fructose and D-glucose contents; (4) Conclusions: The results revealed that Tvien6 and X5 can both individually promote tomato plant growth, increase leaf chlorophyll content, enhance defensive enzyme activities, and induce the accumulation of D-fructose and D-glucose; however, they were more effective when combined.
