“…This disease is caused by Ralstonia solanacearum and it has been considered the main obstacle in patchouli cultivation in Indonesia since this pathogen causes high loss (60-95%) in patchouli production [4] by attacking the plants from seed to adult. This pathogen is difficult to control due to its complexity, where it is polyphagous and can survive in the soil for long period without any host [8]. Besides patchouli, R. solanacearum also attacks potatoes, tomatoes, and other horticultural crops [33][34].…”

Patchouli is the source of an essential oil known as patchouli oil and it has a pivotal contribution to the increase of national income in Indonesia. However, this plant is vulnerable to wilt disease caused by fungi, bacteria and nematodes, contributing to the losses in quality and quantity of patchouli production. This review is aimed at providing information about these destructive pathogens and their effective controls. It is explained that fungus Fusarium solani, bacterium Ralstonia solanacearum, and nematodes Pratylenchus spp. (P. brachyurus and P. coffeae), Radopholus similis and Meloidogyne spp. (M. incognita and M. hapla) have contributed to the loss of patchouli production by different symptoms appeared. F. solani attacks the plant roots, triggering root rot, necrotic and wilt, resulting in the plant’s death. R. solanacearum has colonized the stems and nematodes creating a color alteration in leaves, stunted growth, root rot and wilt during midday. These pathogenic organisms can be controlled by applying preventive measures, biocontrol agents and biopesticides.

“…Mampu menyebabkan penyakit layu pada lebih dari 50 famili tanaman di seluruh dunia (Rivard et al, 2012). Penyakit layu bakteri bersifat endemik dan cepat berkambang dari tanaman yang terinfeksi ke tanaman sehat di daerah sekitarnya (Hartati dan Karyani, 2014) Alternatif yang dapat digunakan dalam mengendalikan penyakit layu bakteri adalah menggunakan penyambungan antara tanaman tomat yang memiliki hasil produksi buah yang baik dengan tanaman tomat maupun terung yang memiliki ketahanan alami terhadap serangan penyakit layu bakteri (Rivard et al, 2012). Penyambungan batang bawah dapat mengendalikan penyakit layu bakteri (R. Solanacearum) mampu meningkatkan produksi tomat di Indonesia.…”

Tomato plant is one of horticultural commodities that plays an important role in agricultural of Indonesia. The production of tomato is constrained by bacterial wilt (R. solanacearum). The development of the disease will increase rapidly in rainy season. This causes the production of tomato decreases for about 30-60%. The alternative effort to control the bacterial wilt (R. solanacearum) done by grafting the commercial tomato plants that are susceptible to noncommercial tomato that have natural resistance to the infection of this pathogen. Suseptible tomato Betavila F1 variety is used for scion. As resistant rootstocks are Rewako F1 and Mawar variety. The grafting done through splice grafting. The experimental design used was Complete Randomized Design with 5 treatments of 4 repetitions with each unit consisted of 5 plants. The observed parameters were incubation period, incidence of disease, severity of disease, infection rate and plant growt. The results of observation data were analyzed by using variance. The grafting treatment between Rewako F1 + Betavia F1 varieties became the best result to inhibit the bacterial wilt of R. solanacearum incubation period 14 Day After Inculation (DAI), incidence of disease 28,00%, infection rate 0,00500 unit/day and necrosis in stem 5,50%. The grafting treatment was not able to increase the component of plant growth. Keywords: Grafting, Tomato, Bacterial wilt disease

Ralstonia solanocearum is a pathogenic bacteria that attacks tomatoes and causes wilt disease. Many efforts have been made to control this disease through cultivation, use of chemical pesticides, and development of resistant varieties, but bacterial wilt disease remains a serious problem economically. Nowadays, many biological controls are being developed using microbes. The use of Bacillus spp as an unfriendly microbe is very potential to control because it has pathogenic inhibitory activity. This study aims to obtain bacterial isolates of Bacillus spp which can suppress the development of bacterial wilt disease in tomato plants. The research was conducted in vitro at the Laboratory of Plant Physiology in the Agriculture Faculty, Unpatti. The results showed that Bacillus niabensis strain PT-32-1 and Bacillus subtilis strain SW116b could inhibit Ralstonia solanacearum, wilt disease in tomato plants in vitro.
