“…Ginger rhizome is widely cultivated as an important economic crop. In ginger cultivation, agricultural diseases and pests are major factors restricting the production and quality of ginger [7][8][9][10][11]. Ginger rhizome rot disease, one of the most destructive diseases of ginger in Shandong Province of China, caused severe rot of ginger rhizomes during later growth stages and heavily threaten ginger production.…”

Ginger rhizome rot disease, caused by the pathogen Bacilluspumilus GR8, could result in severe rot of ginger rhizomes and heavily threaten ginger production. In this study, we identified and characterized a new Bacillus velezensis strain, designated ATR2. Genome analysis revealed B. velezensis ATR2 harbored a series of genes closely related to promoting plant growth and triggering plant immunity. Meanwhile, ten gene clusters involved in the biosynthesis of various secondary metabolites (surfactin, bacillomycin, fengycin, bacillibactin, bacilysin, difficidin, macrolactin, bacillaene, plantazolicin, and amylocyclicin) and two clusters encoding a putative lipopeptide and a putative phosphonate which might be explored as novel bioactive compounds were also present in the ATR2 genome. Moreover, B. velezensis ATR2 showed excellent antagonistic activities against multiple plant pathogenic bacteria, plant pathogenic fungi, human pathogenic bacteria, and human pathogenic fungus. B. velezensis ATR2 was also efficacious in control of aphids. The antagonistic compound from B. velezensis ATR2 against B.pumilus GR8 was purified and identified as bacillomycin D. In addition, B. velezensis ATR2 exhibited excellent biocontrol efficacy against ginger rhizome rot disease on ginger slices. These findings showed the potential of further applications of B. velezensis ATR2 as a biocontrol agent in agricultural diseases and pests management.

“…Fusarium oxysporum f. sp. zingiberi is one of the causes of ginger rhizome rot in the world (Stirling 2004;Li et al 2014), including in Indonesia (Soesanto et al 2003;Wahyu et al 2012). The distribution of rhizome rot disease in ginger has been mapped in eight regencies in Central Java Province; two of them are Boyolali and Temanggung Regencies (Soesanto et al 2003).…”

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.

“…These pathogens considered as most aggressive pathogens causing qualitative and quantitative damage to crop plant and resulted in reduction of yield and economy. Some of these pathogens such as Aspergilus niger, Fusarium oxysporum, Xanthomonas auxonopodis, Psedomonas solancearum and Xanthomonas cucurbitae are causing disease to various crops such as fruit rot (Cherry; Thomidis and Exadaktylou, 2012) [2] , rhizome rot (Ginger; Li et al, 2014) [3] , Bacterial wilt (Tomato and Eggplant; Yenare et al, 2020) [4] , t bacterial blight (Pomegranate; Sherkhane et al, 2019) [5] , leaf spots (Cucurbits worldwide; Maringoni and Leite, 1988) [6] respectively. One of the most widely used strategies to control plant diseases is the use of chemical agents.…”

Cow urine has tremendous applications in agriculture. It is shown to possess inhibitory activity against many phytopathogenic fungi and bacteria. The present study was conducted to determine antibacterial and antifungal efficacy of cow urine. The well-plate assay showed marked growth of inhibition against Aspergilus niger, Fusarium oxysporum, Xanthomonas auxonopodis, Psedomonas solancearum, Xanthomonas cucurbitae by cow urine as well as microbs isolated from cow urine. The TLC and titrimetric analysis were showed presence of lipase enzyme in the cow urine. Moreover, sterilized cow urine can be utilized as natural growth medium for Pseudomonas fluorescence, Bacillus subtilis, mixture of fungi and yeast. The use of cow urine can be the cost-effective and eco-friendly approach for controlling various diseases of plants.
