Fusarium oxysporum f. sp. zingiberi is a soil-borne plant pathogen causing rhizome rot on ginger. This pathogen can survive in the soil for several years without a host plant. This study aimed to examine the viability and virulence of 21 isolates of F. oxysporum f. sp. zingiberi after being preserved for 17 years in sterile soil. Fungal viability was determined by descriptive method, while the experiment using randomized block design was conducted to examine the virulence of fungal isolates. The treatments consisted of control, 21 isolates of F. oxysporum f. sp. zingiberi from Boyolali and Temanggung, each treatment was replicated three times. The variables consisted of colony colors and diameters, macroconidia and microconidia shapes, growth time, dry weight of mycelia, conidia density, incubation period, affected area, rhizome wet weight difference, and waste index. The results showed that all fungal isolates which were stored in sterile soil for 17 years still had the ability to grow well on PDA medium and fill up petri dishes in 11–36 days. Moreover, all the isolates caused infection and disease symptoms development in ginger rhizome var. Gajah. Less virulence isolate was characterized by a long incubation period (6–12 days after inoculation) and smaller affected area of the rhizome.

Efforts to overcome R. solanacearum which causes bacterial wilt (BW) in ginger in peatlands are through a strategy to suppress the initial population. One of the efforts is to use endophytic fungi (CE) as biological control agents. This study aims to examine the use of several endophytic fungi isolates from pepper to suppress bacterial wilt disease and improve the growth of ginger. The treatment of CE biological agents in the form of Aspergillus spp., Fusarium sp., T. harzianum, and T. viride to suppress wilt disease in vivo and the use of biological agents as biofertilizers in the field. The source of the pathogenic bacterium P. solanacearum was obtained from samples of wilted rhizomes from community ginger field isolated on NA media. This study was arranged based on a completely randomized design with five replications. The research variables were wilt disease severity, plant height, number of leaves, number of stems, stem diameter & rhizome weight. The results showed that R. solanacearum caused symptoms after an incubation period of 9 days after inoculation. The four CE isolates were able to suppress the symptoms of ginger wilt in the range of 70-80%. The use of CE isolate was also able to improve the growth of ginger, but it has not been followed by an increase in the production of ginger rhizomes. It is suggested that the use of CE as a biofertilizer needs to be increased in the frequency of its application.

“…Perlakuan yang tercepat menunjukkan gejala penyakit adalah isolat MSO1 dan masa inkubasi terlama terlihat pada isolat PKO3. Apabila dibandingkan dengan penelitian Pancasiwi (2004), masa inkubasi tanaman jahe gajah sekitar 51 hsi maka tidak jauh berbeda. Namun, apabila dibandingkan dengan penelitian Winarni (2004), inkubasi tanaman jahe gajah antara 26-30,67 hsi maka terdapat perbedaan yang cukup jauh.…”

“…Seperti yang telah diketahui bahwa F. oxysporum merupakan patogen yang menyerang pembuluh xilem yang merupakan jaringan pengangkutan air dan unsur hara dari akar ke daun dan seluruh tubuh tanaman. Karena infeksi patogen tersebut, maka akan terjadi penyumbatan di dalam pembuluh xilem sehingga aliran translokasi hara dan air dalam tanaman terhambat (Pancasiwi, 2004).…”

Ginger is one of the spices and medicinal commodities which is cultivated in Indonesia. One of the obstacles encountered in the cultivation of ginger is the rhizome rot disease which is mainly caused by Fusarium oxysporum Schlecht f.sp. zingiberi Trujillo. This study is aimed to know the growth ability and virulence level of the isolates on ginger rhizome and plants. The research was conducted in the laboratory and in the screen house by using Complete Random Design consisted of 10 treatments and 4 replications. The parameters observed were growth ability of F. oxysporum f.sp. zingiberi, rhizome rot disease symptoms, incubation period, extensive decay and weight difference of the rhizomes. The results showed that F. oxysporum f.sp. zingiberi which was stored for 4 years in sterile soil medium was still capable to cause damage to the rhizome and plants. Incubation periods of rhizome decay and plant symptoms were from 3 to 11.5 and 55.5 to 68.5 days, respectively. The most virulent isolate was MSO1 with extensive decay of rhizome and the wilting intensity were 108.95 mm2 dan 33.88%, respectively. IntisariJahe merupakan salah satu komoditas rempah dan obat yang banyak dibudidayakan di Indonesia. Salah satu kendala yang dihadapi dalam budidaya jahe adalah adanya gangguan penyakit busuk rimpang yang disebabkan (terutama) oleh Fusarium oxysporum Schlecht f.sp. zingiberi Trujillo. Penelitian bertujuan untuk menguji daya tumbuh dan virulensi isolat F. oxysporum f.sp. zingiberi pada rimpang dan tanaman jahe gajah. Penelitian dilakukan di laboratorium dan di rumah kasa menggunakan Rancangan Acak Kelompok Lengkap (RAKL) yang masing-masing terdiri dari 10 perlakuan dan 4 ulangan. Parameter yang diamati meliputi daya tumbuh F. oxysporum f.sp. zingiberi, gejala penyakit busuk rimpang, masa inkubasi, luas pembusukan dan selisih bobot basah rimpang. Hasil penelitian menunjukkan bahwa F. oxysporum f.sp. zingiberi yang telah di simpan 4 tahun dalam medium tanah steril mampu menyebabkan kerusakan pada rimpang dan tanaman jahe. Masa inkubasi gejala busuk pada rimpang serta gejala pada tanaman masing- masing berkisar antara 3–11,5 serta 55,5–68,5 hari. Isolat yang paling virulen adalah MSO1 dengan nilai luas pembusukan pada rimpang dan intensitas penyakit masing-masing sebesar 108,95 mm2 dan 33,88%.
