“…These results are similar to the findings of Ishikawa et al 2004 who reported that foliar spray of validamycin-A is effective against black rot of cabbage in pot and field trials. Similarly, Bhat et al (2000) found that foliar spray of chlortetracycline and oxytetracycline resulted in least incidence of black rot.…”

Black rot disease caused by bacterium Xanthomonas campestris pv. campestris has been identified as major cause for low cabbage yields. The present study was conducted to evaluate the efficacy of various antibiotics and bioagents for controlling black rot disease and also their effect on extracellular polysaccharide secretion (EPS) of Xanthomonas campestris pv. campestris. Under in vitro conditions, bacterial proliferation and EPS production were examined on yeast peptone agar medium containing sucrose or trehalose with or without antibiotics. Number of Xanthomonas campestris pv. campestris on yeast peptone agar medium with Validamycin-A was less as compared to control. Extracellular polysaccharide secretion (EPS) was also inhibited on yeast peptone agar medium with antibiotic Validamycin-A. In vivo, disease intensity was recorded minimum in seed treatment + root dipping + foliar spray with Validamycin-A @ 500 µg/ml followed by seed treatment with Validamycin-A @ 500 µg/ml in comparison to control. Similarly, 45.61% higher cabbage yield was recorded in seed treatment + root dipping + foliar spray with Validamycin-A @ 500 as compared to untreated control. However, the antibiotic Validamycin-A which was found effective can be recommended to manage the disease. Bangladesh J. Bot. 52(4): 965-970, 2023 (December)

“…배추과 작물의 검은썩음병을 방제하기 위하여 윤작을 하거나 종자에 물리화학적 처리를 하여 제조한 무균 종자를 재배하는 것이 비교적 효과적이다 (Gangopadhyay and Gill, 1977;McKeen, 1981;Kishun, 1984;Schultz and Gabrielson, 1986;Schaad and Alvarez, 1993). 또한 보르도액과 항생제 등을 이용한 화학적 방제 (Knosel, 1965;Onsando, 1988;Gupta, 1991;Bhat et al, 2000), 길항미생물 Bacillus 균주 배양액을 이용한 생물학적 방제 즉, 식물체의 뿌리를 미생물 배양액에 침지한 후 이식하거나, 배양액을 종자에 침지하여 파종하기 및 배양액을 엽면에 살포하여 검은썩음병을 방제하는 연구가 진행되고 있다 (Jalali and Parashar, 1995;Pichard and Thouvenot, 1999;Wulff et al, 2002). 하지만 우리나라의 기후가 점점 아열대 기후 로 변하면서 검은썩음병 발생도 크게 증가하고 있어(personal communication), 이들 방법을 통한 실질적인 방제효과를 얻기 는 매우 어려운 현실이다.…”

Black rot caused by Xanthomonas campestris pv. campestris (Xcc) is one of the most serious diseases of crucifers world-wide. To establish the efficient screening methods for resistant Chinese cabbage to Xcc, the resistance degree of 88 commercial cultivars of Chinese cabbage to Xcc KACC 10377 was examined. For further study, we selected six Chinese cabbage cultivars (resistant: Mansumugang, Woldongcheonha, CR Anshim; susceptible: Bulam3ho, Chunkwang, CR Nongshim) showing different disease response to the Xcc KACC 10377. According to growth stages of Chinese cabbage seedlings, inoculation density, and incubation temperature and period after inoculation in a dew chamber, development of black rot on the six cultivars was investigated. From the results, we suggest the following method for selection of Chinese cabbage seedlings that are resistant to Xcc. The efficient method is to inoculate 10-day-old Chinese cabbage seedlings with an cell suspension of Xcc at a concentration of 1.0 × 10 8 cfu/mL using the spray method and to incubate the inoculated plants in a dew chamber at 30°C for 48 hours and then transfer to a growth chamber at 25°C with 80% RH under a 12 hour light/dark cycle. Disease severity of the plant can be measured six days after inoculation.

“…In addition to being applied to fruits like citrus, oxytetracycline and streptomycin are also used to treat plant pathogens in edible vegetables, such as bacterial wilt of tomato 18 and black rot of Brassicaceae vegetables (cauliflower, 19 brassica, 20 cabbage. 21 etc), despite the scale of the latter may not be as large as the former. Taking Brassicaceae vegetables as samples, they are susceptible to black rot, one of the most destructive and yield-limiting diseases worldwide, 22 and is caused by Xanthomonas campestris pv.…”

Antibiotics are used to control certain bacterial diseases in plant agriculture. Understanding antibiotic uptake by edible vegetables after application and associated risks on plant microbiome and human health is critical. In this study, oxytetracycline and streptomycin, the two most commonly used antibiotics in plant agriculture, were applied to cherry radish via continuous soil drenching to study their translocations into plant tissues, influence on radish microbiome, and the potential health risk to mice. The results demonstrated that oxytetracycline induced hormesis in radish plants and both antibiotics were translocated into the leaves, fruits, and roots of radishes from the soil, with significantly higher plant uptake of streptomycin than oxytetracycline. Interestingly, the proportion of culturable oxytetracycline or streptomycin-resistant bacteria in the antibiotic-accumulated radish tissues was significantly higher than that in the antibiotic-free radish tissues, although both bacterial and fungal communities in different radish tissues were not affected by the accumulated antibiotics, demonstrating that antibiotic application could enrich antibiotic resistance in the plant microbiome. Feeding mice with antibiotics-accumulated radish tissues did not show significant effects on the weight and blood glucose levels of mice. Overall, this study provides important insights into the risk of using antibiotics in plant agriculture.
