Except growth stage and previous crop at flowering stage as well as previous crop at vegetative stage, the other variables association were negative with disease parameters at both stages (Table 4 and 5). Brar, J., T. Bains, S. Shanmugasundaram and S. Singh. Plant Pathology Journal 6(3):235-241. Phytopathology 61:1430-439. However, productivity of mung bean is decreased through biotic and abiotic stresses; including diseases, insect pests, drought stress, water stress, extreme high temperature, salinity stress as well as heavy metals (Waniale et al., 2012; Das et al., 2014). Access scientific knowledge from anywhere. Thus, it is necessary to investigate the geographic distribution of foliar devastating bacterial and disease to know the intensity and characterize the causal agent of the disease. Among districts surveyed, mean maximum severity of bacterial brown spot of mung bean was noticed at Kalu (50.73%) followed by Kewot (42.07%) (Figure 2). Dickey RS, Kelman A (1988). In addition, the disease rapidly spread and emerged in many mung bean planting areas and is causing a series of mung bean yield losses, making the disease a major threat to mung bean production in the areas. The average annual rainfall is 1030 mm. Seed of check cultivars Raven, Midnight, Shiny Crow, and T-39 were compared to Shiny Black Pearl for water uptake after 16 hours soaking for three years of production at Fort Collins, CO. Pakistan Journal of Weed Science Research 18(2):191-200. The annual average rainfall of the district ranges from 750 to 900 mm. Yellow mosaic virus and foliage beetle (Ootheca spp.) 28-45. Considering the proliferation of journals publishing food science and human nutrition related work, especially in the Third World countries, the actual number probably would be much higher. Index … Sample collection was performed immediately after the appearance of the initial symptoms in early August and September in 2018 main growing season. In India and some South Asian countries, the crop plays important dietary protein source in predominantly cereal rich diets. MungBean (Vigna radiata (L.) Wilczek) (Fabaceae) Landrace Diversity in Ethiopia. In addition to this, proposed variety needs no special production technology package and fit in a better way in Rice-Wheat cropping system or between wheat and succeeding crop as catch crop due to short duration. Those mixed bacterial colonies were purified and grown on nutrient agar. Australasian Plant Pathology 35:65-67. Mung bean cultivation technology Pakistan Dr.Ashraf Sahibzada - Duration: 9:40. for 15 min and cooled without slanting. The mean disease incidence of bacterial brown spot on mung bean showed 80.6, 83.3 and 74% at Kewot, Kalu, and Tehuledere districts respectively at flowering stage (Figure 2). African Crop Science Journal 19(4):357-367. As colony morphology on agar surface aids to identify the bacterial isolates, each isolate from colonies of characteristic shape, size and appearance were observed. Mungbean Project for 2002-2004: 61. High mean disease intensity observed in all agro-ecologies might be associated to the poor cultural practices adopted by smallholder farmers in the area including use of poor quality farmer-saved seed sources, lack of crop rotation and poor management practices exacerbated by conducive environment conditions for disease development (Njingulula, 2014; Kijana et al., 2017). Diseases of mung bean in India. copyright of this article. To test for the levan production of the isolates, a nutrient agar plates containing 5% sucrose were streaked by the test isolates and incubated for 3-5 days at 30°C. Methods in Phytobacteriology, Akademiai Kiade, Budapast, Hungary. The association of disease severity and adjacent crop showed negative and significant association at flowering and vegetative stage respectively at significance level (Tables 4 and 5). The authors have not declared any conflict of interests. 2004. The isolates were negative for oxidase reaction, starch hydrolysis (Figure 7), potato soft rot, hydrogen sulfide (H2S) production, lactose tests and were positive for KOH (Figure 10), catalase (Figure 11), Aesculine (Figure 6), iron-deficient   media   (Figure 8),   tween   80   hydrolysis (Figure 9), gelatin liquefaction, nitrate reduction, levan production, sucrose, mannitol, sorbitol, maltose, inositol and dulcitol tests (Table 3). Kombolcha, Ethiopia. vignaradiatae) of Green Gram in DifferentTehsils of Udaipur District, Rajasthan, India International Journal of Current Microbiology and Applied Sciences 7(3):2924-2931. All rights reserved. Klement Z (1990). About (64%) of the adjacent crops observed in accordance with mung bean fields were cereals (Table 1). Improving Income and Nutrition by Incorporating Mungbean in Cereal Fallows in the Indo-Gangetic Plains of South Asia DFID Mungbean Project. South Africa. The epiphytic nature of the pathogen on weeds could result to grow and survive on the main host. It was reported as the most widespread bacterial disease of dry bean in South Africa and yield losses of up to 55% was noticed (Serfontein, 1994). Pedigree, bulk or single seed descent methods are suggested for developing elite populations. Shiny Black Pearl has shiny seed coat luster, similar to the cultivar 'Shiny Crow'. Agro-morphological characterization of exotic and local green gram mung bean (Vigna radiata) for breeding purposes in Uganda, P. 28. (2018). Based on the laboratory diagnosis a newly emerging disease of mung bean named as bacterial brown spot of mung bean (P. syringae pv. International Journal of Pest Management 60(4):314-324,  Archives of Agronomy and Soil Science: Vol. The variety was derived from a single F 4:5 plant selection in 2001 from the pedigree ARA 13/UI 906//H9652-5. in which the pathogen completes Its life cycle without affecting the normal development of the plant, has potential for providing durable resistance to the disease. From the total annual production Amhara region produces 35297.25 tonnes annually. Commons Attribution License 4.0. Thus, the bacterial multiplication and movement within the plant cells could be reduced and lower the inoculum. Variation in disease prevalence and intensity across locations would be attributed to prevailing environmental conditions and crop management practices, which was reported by Scheuermann et al. Mung bean–associated symbionts have been identified from various regions of South Asia through polyphasic studies, but from Pakistan, detailed studies are lacking. Waniale A, Talwana H, Wanyera N (2012). 33-40. There are two possible ways to increase the area under mung bean: Through inter-cropping of mung in seasonal sugarcane crop; Through sowing of mung soon after harvesting of wheat; Seed rate and time of sowing: Use 6-8 kg per acre certified seed of mung bean … The plates were incubated at 30°C for 24 to 48 h; while each plate was examined for culture growth. The factors result from the system itself and include change in microclimate, reduced host density, induced resistance and competition.
